Ever stood in downtown Durango and wondered, “What was *this* building before it was a coffee shop… or a boutique… or a patio?” The fastest way to time-travel—without dragging the family through a museum placard marathon—is a set of Sanborn Fire Insurance Maps from **1910**. They’re packed with little clues that show **exact building shapes (footprints), materials, and what each place was used for**—right down to stores, hotels, sheds, and stables.
Key Takeaways
– Sanborn Fire Insurance Maps are old maps made to help with fire safety, so they show buildings in close detail.
– The 1910 Durango Sanborn maps show each building’s shape, size, material, and what it was used for (like store, hotel, saloon, stable).
– Start by finding the right sheet: open the Durango map set on the Library of Congress site and use the key map/graphic index first.
– Use anchors that do not move to get your bearings: the Animas River, the railroad tracks, bridges, and the street grid.
– Read each building in the same order every time:
– Shape and where it sits (at the sidewalk, set back, or stretching toward an alley)
– Color/material (often yellow = wood, red/pink = brick when color is shown)
– Stories/height marks (like 1 or 2, or 1 sty)
– Extra symbols and notes (like special walls, stairs, or hazards)
– Check the scale printed on the sheet so you can tell if something is a main building or just a small shed or add-on.
– Use labels and abbreviations as hints, then double-check using nearby buildings and the building’s location on the block.
– Common words to know:
– footprint = the building’s outline on the map
– lot = the piece of land a building sits on
– block = the area surrounded by streets
– dwelling (D or Dwg) = a home
– store (S) = a shop
– sty = number of stories (floors)
– Watch out for mistakes:
– Some pages may have later updates pasted on, even if they say 1910
– Black-and-white scans can hide the color clues
– The maps do not show everything, only what mattered for fire insurance
– Easy walking plan:
– Save a few map sheets to your phone before you go
– At each stop: look up at the real building, look down at the map, then look toward the alley/rear area
– Stay on public sidewalks and be respectful around homes and businesses
If you want to use this guide on a real trip, keep it simple and repeatable. Pick one small downtown area, save the sheet to your phone, and let the map do the heavy lifting while you do the walking. When you get stuck, don’t hunt for “the perfect symbol” right away—go back to anchors like the river, the tracks, and a clear intersection, and you’ll usually pop right back into place.
The best part is how quickly your eyes learn the pattern. After you read a few footprints in the same order, you’ll start noticing the “behind the scenes” side of town: rear add-ons, alley access, and buildings that used to have a totally different job. That’s when the map stops being something you stare at and becomes something you use. And that’s what makes the whole “then vs. now” experience feel like a game instead of a lesson.
Now let’s turn those takeaways into a simple downtown game you can actually play.
Here’s the fun part: once you know what to look for, these maps turn a stroll from Junction West Durango Riverside Resort (hello, **Animas River** landmark!) into a real-life “then vs. now” game. **Yellow or red?** That’s your first hint. **A weird L-shaped outline behind a storefront?** That can signal kitchens, storage, or workspaces. **Tiny letters inside a building?** That’s where the stories hide—*and where most people give up.*
Keep reading and you’ll learn a simple, no-jargon way to: **find the right map sheet fast, read a building footprint in the right order, and decode the most common use labels**—so you can spot the old hotels, bakeries, saloons, and shops on purpose (and not just squint and guess).
Before we jump in, one quick reality-check that actually makes this easier: Junction West is about 15 miles north of downtown. So think of this as a short drive into town, then a walk where you compare your phone screen (the 1910 map image) to the buildings right in front of you. The map is the time machine; your feet are the “play” button.
What Sanborn fire insurance maps are (and why they feel like a puzzle at first)
Sanborn maps were made for fire insurance, not sightseeing. That’s why they obsess over building materials, walls, hazards, and access points instead of scenic viewpoints or “best coffee” icons. Once you know that, the busy-looking symbols start to make sense: they’re the map’s way of answering one question over and over, which is “How risky is this building if there’s a fire?” The Library of Congress breaks down how to read them in the Sanborn guide, and it’s worth using that lens as you explore.
That fire-insurance purpose is also why these maps feel like a secret decoder ring for modern visitors. A normal old street map might show roads and a few big landmarks, but a Sanborn sheet zooms in to building-by-building detail. It shows footprint shapes, how close structures sit to one another, and the way alleys and back doors work. In a historic town like Durango, that means you can look at one block and instantly see where lodging clustered, where deliveries likely happened, and where the “work” buildings sat behind the “front” buildings.
If you’re traveling with kids, the trick is to treat the page like a scavenger hunt instead of homework. You’re not trying to memorize a legend. You’re trying to spot clues that answer fun questions like, “Which corner probably sold snacks in 1910?” or “Where would the horses have been kept?” Once you start thinking that way, the map stops being a wall of symbols and turns into a storybook you can walk through.
How to find the 1910 Durango Sanborn maps online (fast, no scrolling forever)
The cleanest starting point is the Library of Congress item page for the Sanborn Fire Insurance Maps of Durango, Colorado. This Durango set was created by the Sanborn Map Company and published in November 1910, and the Library of Congress provides 13 sheets as public domain images you can view or download from the LOC item. It’s built for zooming, which matters because the “tiny letters” are where the real stories live.
Here’s a simple workflow that works on a phone, even if you’re planning your day over breakfast. Search within the Library of Congress Sanborn Maps Collection for “Durango La Plata County Colorado Sanborn,” then open the Durango set and look for the key map or graphic index first. The goal is not to click Sheet 7 because it sounds lucky. The goal is to grab the overview that tells you which sheet covers which part of town, then go straight to the page you actually need.
There’s also a helpful companion portal called Building Colorado Story by Story, which offers high-resolution viewing, metadata, keys, and teaching tools for many Colorado cities and years. It may or may not contain Durango specifically, but it can still be useful for learning Sanborn conventions without pressure. Think of it like practicing the “map-reading moves” so your first downtown comparison feels smooth.
Once you have the Durango sheets open, save a few to your phone before you head out. A screenshot works in a pinch, but downloading the high-res image is even better because you’ll zoom way in. The moment you can pinch-zoom and read a small use label without squinting, you’ll feel the whole system click.
Match a 1910 sheet to today’s Durango using anchors that don’t move
Sanborn maps aren’t modern road maps, so the fastest way to get oriented is to start with features that rarely move. In Durango, two of your strongest anchors are the Animas River corridor and the railroad alignment. Rivers don’t politely relocate between editions, and rail corridors tend to hold their shape even as buildings around them change. So before you hunt for one storefront, look for the big lines: the river curve, the tracks, bridges, and the main street grid.
Now do it in a repeatable order, because the order is the secret weapon. First, find the anchor (river or rails). Second, find the biggest streets near that anchor. Third, lock onto a recognizable intersection and confirm the block shape and the way the lots are cut up. Block geometry is your best friend when street names or address numbers don’t match modern signs, and the Sanborn guide explains why using the graphic index and street index together saves time when you’re hopping across sheets.
Here’s a guest-friendly “base camp” move if you’re staying at Junction West Durango Riverside Resort: start with the river as your mental compass. Even though you’ll drive into downtown for the actual walk, the Animas is easy to recognize on the map sheets, and that gives your brain an instant left-right orientation. Then you trace from the river corridor toward denser downtown blocks, using intersections and block shapes like stepping stones.
Mini-challenge for families: pick one downtown block and give it a nickname before you arrive, like “Hotel Block” or “Snack Corner.” On the map, circle an intersection you can find today with near-zero effort (a major crossing or a spot near the tracks). When you reach that spot, ask the kids to “prove” you’re on the right block by matching the alley position and block shape, not just reading a street sign.
And if something doesn’t line up, don’t assume you’re wrong. Assume Durango changed. When the label or numbering feels off, trust what doesn’t lie: intersections, angles, and the way a river bends.
Scale: the quick trick that turns tiny footprints into real-world sizes
Sanborn maps look like drawings until you remember they’re measured. Most urban Sanborn sheets use a standard scale that’s often 1 inch equals 50 feet (1:600), though some sheets use 1 inch equals 100 feet (1:1,200) or 200 feet (1:2,400). Those common scales and what to check are explained in the University of Virginia’s Sanborn details. The key is to use the scale printed on the exact sheet you’re viewing, because that’s the one that turns the footprints into real distances.
Once you have the scale, you can do a quick reality check that prevents the most common “oops” moment: mixing up a main building with a small shed or rear add-on. If a footprint is a tiny rectangle tucked behind a larger structure, the scale helps you decide if it’s a meaningful outbuilding or just a small support space. That matters because “small outbuilding” and “main business” tell two completely different stories about how the block worked.
Try this without any special tools. Pick a storefront-style footprint that sits tight to the sidewalk and look for any measurements printed along walls or lot lines. Then compare that approximate width to what you see on the street today. You don’t need perfect math; you just need a sense of whether you’re looking at something closer to 20 feet wide or 80 feet wide, because that one habit makes your “then vs. now” matches feel confident instead of hopeful.
For couples and quick-stop travelers, scale also helps you spot the “backstory” details faster. When a rear extension is big enough to matter, you start asking better questions. Was it a kitchen, a workshop, storage, or a loading space connected to an alley? Those questions make even a short downtown stroll feel like a discovery.
Read one building footprint in the right order (so you don’t miss the good clues)
If you only learn one skill, make it this: read a footprint in the same order every time. Start with the outline shape and how it sits on the lot. Is it flush to the sidewalk, set back with space in front, or stretching deep toward an alley? That one observation can instantly change what you look for when you turn your head in real life.
Next, check construction material, especially if you have a color scan. On many Sanborn maps, yellow commonly indicates wood-frame construction, while red or pink commonly indicates brick or masonry, and other colors can signal stone, concrete, or metal as described in the Sanborn details. If you’re viewing black-and-white scans, slow down and rely more on printed notes and the legend than on shading guesses.
Then look for story or height notation. You’ll often see marks like 1 sty, 2, or similar shorthand, and once you notice them, you start seeing downtown differently. A one-story box with a long rear section reads like “business up front, work behind,” while a taller building can hint at rooms or living space above a storefront.
Last, scan for special features and line styles. Sanborn maps use symbols and line types to flag details that mattered for fire risk and access, like fire walls, exterior stairs, and other marked features, which the Sanborn guide helps interpret. You don’t need to learn every symbol; you just need to notice when a footprint has extra information and treat it like a “zoom in here” sign.
Here’s what to look for on the ground as you walk. If the map shows a long rear extension, peek down the side of the building for an alley door, a loading area, or an old service entrance. If the map shows multiple attached shapes, look for rooflines that step up and down, because that can reveal additions even when the front façade looks tidy.
Mini-challenge: pick one building you can see today and guess its footprint shape before you look at the sheet. Then check the map and see how close you were. The best surprises often come from buildings that look small from the front but stretch deep into the block.
Use labels and abbreviations to spot old hotels, shops, bakeries, and stables (without getting stuck)
Sanborn maps label buildings by use, and that’s where the “what used to be here?” magic really lives. You’ll see labels and abbreviations for things like dwelling, store, saloon, and many specialized uses, and the UVA Sanborn details outlines how these conventions work. The trick is to treat each label as a hint, not a final answer, because the map is most powerful when you combine text clues with location and footprint shape.
Here’s a visitor-friendly method for decoding an unfamiliar abbreviation without getting stuck. First, use context clues before you touch a legend: is it on a busy corner surrounded by other commercial labels, or mid-block among mostly dwellings? Second, compare within the same sheet, because Sanborn volumes are usually consistent inside one set. Third, look at adjacency: rail corridors, large yards, tanks, and utility notes often suggest service or industrial uses even if a label is short.
A mini glossary that covers what most people need on a first trip:
– footprint: the drawn outline of the building as it sits on the ground
– lot: the parcel of land a building sits on, often shown within a block
– block: the area surrounded by streets, holding multiple lots
– dwelling (often shown as D or Dwg): a home or residence
– store (often shown as S): a shop
– sty: stories, or how many levels the building had
Now the fun spotting game: hotel versus store versus stable. Hotels and lodging often cluster near transportation and busy streets, and they may have larger footprints with multiple parts. Stores often sit tight to the sidewalk, especially on corners, and they can appear as rows of rectangles facing the street. Stables and service buildings often sit back from the street with access from an alley or yard, and the footprint arrangement can hint at how animals, deliveries, or work moved through the space.
When you find something that feels like a “wow,” capture it in a repeatable note. Write down the sheet number, the block, the label, and one real-life observation about what still exists. That keeps your discoveries from disappearing into the blur of vacation photos.
How to avoid the biggest misreads: revisions, paste-overs, and what the maps don’t try to show
The Durango Sanborn set is dated November 1910, but some copies can include later updates through paste-on correction slips. That means you can have a page that says 1910 at the top while a specific building footprint or label was updated later. The LOC item confirms the Durango set details, and the Sanborn guide explains how corrections and revision practices show up on maps. So when you see a patch or pasted change, treat it as a clue that time is layered right on the paper.
Another easy mistake is assuming the map shows everything that mattered to people in 1910. It shows what mattered for fire insurance, in detail, which is why you’ll see precise footprints, building materials, and access. But social details or “tourist-worthy” notes often aren’t there unless they affected risk, and a blank footprint is not proof of “no use.” Sometimes it simply means the mapmaker didn’t need to specify beyond shape and material.
Finally, be careful with black-and-white scans. Color is a big part of Sanborn material coding, and if the scan hides color, your brain will try to fill it in anyway. When color is unclear, lean harder on printed notes, labels, and the legend guidance in the Sanborn guide rather than guessing materials from shading.
If you want one simple rule that keeps you accurate: don’t make a big claim from one clue. If you think a building was a bakery or a hotel, look for a label, a footprint layout that fits, and nearby buildings that support the idea. It’s always fine to say “the map suggests,” because that keeps the exploring fun and the history respectful.
A simple “then vs. now” walking workflow (safe, respectful, and actually fun)
Do your map prep like you’re packing a day bag: light, practical, and focused. Pick a theme before you go, because themes keep kids engaged and keep adults from trying to read all 13 sheets at once. Easy themes include “hotels and travel,” “shops on corners,” or “river and rail,” and you can use the key map/graphic index to grab just a couple of blocks that match your theme.
When you get downtown, build your walk around safe navigation and simple comparisons. Choose sidewalks and controlled crossings, and remember that traffic patterns today won’t match the 1910 street scene. Then use a three-step rhythm at each stop: look up at the real building, look down at the footprint, then look toward the alley or rear area to see if the “back-of-house” story still shows itself.
Keep the etiquette easy. View buildings from public rights of way, don’t wander into yards or posted alleys, and keep noise low in residential areas. If you’re taking photos, aim for architecture and streetscape, not people, and you’ll keep the experience comfortable for everyone around you.
If you want to turn it into a game, here are three quick wins that work for families, couples, and solo travelers:
– Find a corner store on the map, then stand on that same corner today and compare the footprint shape to the current building line.
– Pick one block and hunt for rear additions, then look for clues like side doors, loading spots, or roofline changes.
– Choose one mystery abbreviation, decode it using “compare within the same sheet,” then write it down in your personal legend so the next one is faster.
Once you get the hang of footprints, colors, and a few simple labels, the 1910 Sanborn sheets stop feeling like “old maps” and start working like story-lenses. Every corner shop, long rear add-on, and alley-facing outbuilding becomes a clue you can spot in real life—and suddenly a quick downtown stroll turns into a memorable “then vs. now” adventure you can share with kids, friends, or your favorite travel partner.
If you want the perfect home base for that kind of Durango time-travel, make Junction West Durango Riverside Resort your landing spot. Spend your mornings riverside along the Animas, head into town with a few saved map sheets and a theme, then come back to clean, comfortable lodging, space to unwind, and an easygoing place to swap your best finds near the community fire pit by the pool.

Frequently Asked Questions
Sanborn maps can look dense at first, but most visitors only need a handful of repeatable moves to enjoy them. Start with the key map/graphic index, pick a small area you’ll actually walk, and give yourself permission to ignore most symbols on day one. The more you compare one block carefully, the faster the “map language” becomes second nature.
These answers are meant to keep your exploring accurate, easy, and fun. When you see something unusual, slow down and use context: nearby labels, the footprint shape, and the block layout usually explain more than a single abbreviation by itself. And if a scan is black-and-white or a page shows pasted updates, lean on printed notes and cross-check patterns on the same sheet before making a confident call.
Q: What is a Sanborn Fire Insurance Map, in plain English?
A: A Sanborn map is a super-detailed city map made for fire insurance companies, so it focuses on what buildings were made of, how big they were, what they were used for, and how close they sat to each other, which is exactly why it’s so useful today for “what used to be here?” exploring.
Q: Where can I find the 1910 Sanborn maps for Durango online?
A: The easiest place is the Library of Congress page for “Sanborn Fire Insurance Maps of Durango, Colorado,” where the November 1910 set is available as public-domain images you can open, zoom, and download by sheet.
Q: Do I need to read all 13 sheets to enjoy this?
A: No, it’s more fun (and less overwhelming) to use the key/index first, pick just one or two downtown blocks you plan to walk past, and zoom in on those sheets so you’re comparing a small area really well instead of skimming everything.
Q: What does “building footprint” mean on these maps?
A: A footprint is simply the outline of the building as it sat on the ground, and the shape matters because it can reveal things you might not notice from the front—like rear add-ons, attached sheds, and L-shapes that hint at back rooms, work areas, or storage.
Q: What do the colors mean (like yellow and red)?
A: On many Sanborn maps, color is a quick material clue—yellow commonly indicates wood-frame buildings and red/pink commonly indicates brick or masonry—so color is often your first “at a glance” hint about construction before you even read the labels.
Q: What if the map I’m viewing is black-and-white and I can’t see the colors?
A: If the colors aren’t clear, rely more on the printed notes, abbreviations, and the map’s legend/keys (plus comparisons to nearby buildings on the same sheet), and avoid making confident claims about materials based only on shading or guesswork.
Q: What does “1 sty” or “2” mean inside a building?
A: Those notes indicate how many stories (levels) the building had, so “1 sty” means one story, and that small detail can change how you imagine the place—like a simple one-level shop versus a two-story building that may have had rooms or living space above.
Q: How do I figure out what a building was used for (store, hotel, saloon, stable)?
A: Start by reading the label inside the footprint if there is one, then sanity-check it with context: buildings tight to the sidewalk in a row often read like storefronts, larger multi-part buildings in busy areas can suggest lodging, and structures set back with access from an alley or yard space often fit service uses like stables or work buildings.
Q: I keep seeing tiny letters—how do I decode abbreviations without getting stuck?
A: Treat abbreviations as hints, not final answers, and use the same-sheet trick: find the same abbreviation elsewhere on the page and compare the neighbors and location, because Sanborn volumes are usually consistent within a set and repeated patterns make the meaning clearer.
Q: How do I match a 1910 Sanborn sheet to what I’m seeing downtown today?
A: Use “anchors that don’t move” first—the Animas River, the railroad tracks, bridges, and the street grid—then confirm intersections and block shapes before you zoom in on a single building footprint.
