Why do the slopes above Highway 550 look as if a giant took a paint roller to the snow—leaving raw, russet streaks that refuse to hide even in summer green? Those dramatic stripes are avalanche slide scars, and they tell a story as wild as the San Juan peaks themselves.
Key Takeaways
– Highway 550’s brown stripes are avalanche scars on Red Mountain Pass, about 45 minutes north of Junction West.
– Snow slides scrape away trees and soil again and again, so the stripes stay bare all year.
– Safe pullouts: milepost 79.5 and 80.1 (southbound) and milepost 90 (northbound) give room for photos without blocking traffic.
– Altitude jumps 5,000 feet; bring water, layers, and watch for quick weather changes.
– CDOT uses remote “snow cannons” to blast small avalanches early; respect road closures and red-and-white avalanche signs.
– Best photo light: morning for east-facing slopes like Mother Cline, after 4 p.m. for west-facing slopes like Blue Willow; a polarizer helps colors pop.
– Traction Law may require winter tires or chains; carry an emergency kit with shovel, blanket, snacks, and power bank.
– Back-country travel needs beacon, shovel, probe, partners, and a filed plan—low danger is not no danger.
– Fuel up in Durango, leave before 8 a.m., and plan a half-day loop so you’re back at Junction West for evening campfire fun.
Whether you’re buckling kids into the minivan, easing a 30-footer up the Million Dollar Highway, scouting sunrise shots for Instagram, or timing a back-country skin track, understanding those scars turns a white-knuckle drive into an eye-opening adventure. From “Mother Cline” to “Blue Willow,” we’ll show you where to pull over safely, why the slopes keep shedding trees, and how to photograph the scars without holding up traffic.
Stick with us—by the time you zip (or cruise) back to your riverside campfire at Junction West, you’ll see every brown ribbon on Red Mountain Pass as a moving postcard, not a mystery.
Quick-Glance: Why You’ll Love—and Respect—This Drive
The pass sits only forty-five minutes north of Junction West, so even casual travelers can turn the outing into a half-day loop that leaves room for riverside play or a hot-spring soak later. Elevation jumps more than 5,000 feet, so your dashboard thermometer and your sense of wonder both spike quickly. You’ll get hair-raising corners, alpine vistas, and the chance to see avalanche power without ever stepping off the pavement.
No matter your rig—a family minivan, a 30-foot motorhome, or a compact SUV hungry for Instagram gold—designated highway pull-outs make the stop easy. Each overlook was built to keep tourists out of traffic lanes and right in the viewfinder sweet spot. From those safe shoulders you can count the “tiger stripes,” snap mid-morning photos that glow with side light, and still have room to set up a picnic blanket for restless kids or pups.
Meet Red Mountain Pass
Red Mountain Pass tops out at about 11,200 feet (3,414 m) on U.S. 550 between Silverton and Ouray. The route’s better-known nickname, the Million Dollar Highway, hints at both its costly construction and its priceless views. With 8 percent grades, tight switchbacks, and stretches without guardrails, the road commands respect while rewarding drivers with panoramas of the San Juan Mountains, San Juan National Forest, and the famous Idarado Mine tailings.
Because the pass sits in a subalpine snow factory, winter storms dump huge loads that often arrive on fierce winds. Those winds pack slabs onto 35- to 45-degree starting zones—the ideal angle for a snow slab to rip loose. Over decades the slides have carved signature paths like Mother Cline, Blue Point, and Blue Willow, leaving scars that stay visible through every season.
Why Those Brown Stripes Stay Bare
When snow finally gives way, it behaves like liquid concrete—shearing off trees, topsoil, and even boulders. Each new slide scrapes the surface clean again, so seedlings never get the decades they need to mature. Even summer monsoons can’t hide the damage; the exposed earth dries into a rust-colored ribbon you can spot from miles away.
Since 2023, CDOT avalanche systems have used remote-controlled Gazex and O’Bellx cannons to knock loose smaller slabs before they grow big enough to threaten motorists. Picture giant steel horns and egg-shaped “blasters” tucked high on the ridges, rumbling the snowpack during dawn closures so you can drive later in the day. The repeated scouring keeps vegetation in a constant restart mode, an ecological time-loop that makes the landscape a living science lab.
How to See the Scars Safely
Southbound from Silverton, pull-outs at mileposts 79.5 and 80.1 are your best bets. The first has ample space for RV slide-outs and a wide angle on Blue Point. The second sports a kid-high guardrail and a direct line on Mother Cline—perfect during mid-morning when east-facing slopes glow.
Northbound from Ouray, the Idarado Mine turnout at milepost 90 adds summer toilets and room to stretch your legs while Blue Willow’s west-facing strip turns golden after 4 p.m. In winter, Commodore Gulch’s gate sometimes opens for controlled viewings of debris piles—obey every closure sign, because the red-and-white “Avalanche Area” placards mean the slope above you can still fire. Early summer is the photographer’s jackpot: lingering snow outlines each lane, and a simple polarizer cuts glare so the stripes pop.
Door-to-Door Logistics From Your Junction West Basecamp
Plan for about two hours each way if you love photo stops or traffic-control pauses. Roll out before 8 a.m. to find open parking and to stay ahead of mid-day RV convoys. The resort desk can pack a “grab-and-go” breakfast and hand you a printed CDOT update so you’re not scrambling for cell service in the canyon.
Fuel is your lifeline; top off in Durango because there’s nothing but scenery and the faint smell of brake pads between town and Silverton after 5 p.m. The altitude leap from 5,700 feet at the resort to 11,200 feet at the summit can trigger headaches, so hydrate the night before, eat a light breakfast, and pace that first walk to the guardrail.
Road-Safety Basics for Casual Motorists
Colorado’s Traction Law often pops up without warning between October and April, so mount winter-rated tires or carry chains even if the sun is shining. Stash an emergency kit with a shovel, blanket, headlamp, snacks, and a phone power bank; crews may close gates for hours while they blast hang-fire.
Never park inside zones marked by red-and-white avalanche signs. Slide 100 yards past the sign before you pull over, then set the brake and flip on hazards if visibility drops. Check cotrip.org at the resort before you lose Wi-Fi—cell gaps begin ten miles north of Durango and last well into the high country.
Avalanche Ecology That Kids and Camera Lenses Love
Slide scars are textbook examples of early ecological succession. Because slides wipe the slate clean so often, fireweed and Colorado columbine rush in like nimble first responders, splashing purple and white along the margins by late June. Send kids on a “purple-flower count” and they’ll learn botany without realizing it.
Meltwater funnels down these open lanes, scooping up fine sediment that splatters onto the highway each spring. Now you know why snowplow berms hide wet mud patches until July. Fallen logs in the runout zones become condo complexes for weasels and snowshoe hares—great to watch, terrible to climb on, so keep feet on durable surfaces and fingers off the wildflowers.
Stepping Off the Road? Read This First
Backcountry curiosity demands its own rulebook. Every member of your party needs a beacon, shovel, and probe, plus enough practice to use them without Google or guesswork. Travel in groups of three or more so one person can stay with an injured friend while another hikes out for help.
Incidents such as the CAIC incident report at “Bollywood” prove that a LOW danger rating never equals NO danger. Stick to slopes under thirty degrees, avoid fresh cracks or hollow “whumphs,” and file your plan with the resort office before you lose service. Returning for check-in keeps search-and-rescue teams free for real emergencies—and earns you bragging rights around the firepit.
Segment Snapshots: Tailored Tips in 60 Seconds
When time is tight, quick-reference advice keeps everyone moving safely while still snagging postcard-worthy photos. Think of these snapshots as cheat codes for the Million Dollar Highway: they highlight which pullouts pair best with lighting, traffic lulls, and the vibe of your crew. Read through once, then match the bullet that fits your day so you spend less time scrolling and more time staring at peaks.
Each tip distills local wisdom collected from rangers, photographers, and shuttle drivers who roll this road daily. By following their timing tricks—like aiming for Tuesday mornings or slipping behind a guided tour van—you stack the odds of a smooth ride. Small moves such as downloading audiobooks early or picking the one-car turnout at mile 87.3 turn a popular byway into your personal playground.
• Families: Overlook #2 offers guardrails, picnic space, and mid-morning light—download audiobooks first because cell service fades.
• Retired scenic-byway explorers: Tuesday–Thursday mornings have light traffic; skip driving altogether with a San Juan Backcountry Tours shuttle.
• Instagram couples: Milepost 78 glows at sunrise; wrap up with craft pints in Silverton.
• Dawn-patrol adventurers: Park neatly at Gate 3, leave a plan, and respect CAIC advisories.
• Budget backpackers: Ride Bustang to Silverton, walk to Overlook #1, and score million-dollar shots for free.
• Romantic duos: Sneak off to the tiny turnout at milepost 87.3 for sunset before soaking in Ouray’s hot springs.
Pack-and-Go Checklist
Packing smart means you’ll spend less time worrying about forgotten gear and more time gawking at avalanche strips. The San Juans swing between sunburn and sleet in a single hour, so layers and backups are your best friends. Treat this checklist as your insurance policy against altitude headaches, dead batteries, and roadside delays.
Run through the items the night before, stashing them where you can reach them fast—your driver-side door pocket, the lid of your backpack, or an under-seat bin for larger rigs. On the road, you’ll thank yourself when the traction law lights flash or an impromptu photo op appears around a blind curve. A little prep equals a lot of peace of mind.
Full fuel tank • 2 L water per person • Layered clothing for a 20 °F swing • Sunglasses & sunscreen • Polarizing filter • Printed road status • Emergency kit (shovel, blanket, snacks, power bank) • Extra curiosity

Frequently Asked Questions
Q: Is Red Mountain Pass a safe summer drive for families with young kids?
A: Yes, summer is the calm season on the pass: the pavement is clear, avalanche risk is low, and CDOT patrols daily, so children can enjoy the ride as long as an adult stays buckled in, obeys the 25–35 mph curves, and uses the signed pull-outs for stretch breaks.
Q: What causes those huge brown stripes on the mountainsides?
A: The stripes are avalanche slide scars—lanes where recurring winter snow slides scrape away trees and soil; because a new slide resets the slope every few years, vegetation never grows tall enough to hide the raw, rust-colored earth.
Q: How far is the pass from Junction West and when should we head out?
A: Plan on about 45 minutes to Silverton and another 15 minutes to the summit, so leaving the resort before 8 a.m. gets you bright light on the east-facing scars, easy parking, and plenty of time to be back for an afternoon river dip.
Q: Are there kid- and RV-friendly pull-outs for quick photos?
A: Mileposts 79.5, 80.1, and 90 each have wide paved shoulders, room for a 30-foot motorhome or minivan doors to swing, and guardrails or flat ground where kids can safely snap pictures without stepping into traffic.
Q: When is traffic lightest so nervous or retired drivers can take it slow?
A: Mid-week mornings—Tuesday through Thursday before 10 a.m.—see the fewest vehicles, letting you coast in low gear, pause at every overlook, and glide through the switchbacks without feeling pushed by faster cars.
Q: Can we book a guided shuttle instead of driving our own rig?
A: Yes, San Juan Backcountry in Silverton runs half-day van tours that handle the steering while you handle the camera, and they’ll pick up at the Silverton train depot, which has free parking for larger RVs.
Q: Where is the most photogenic sunrise spot for Instagram shots of the scars?
A: Pull-out 78.0 southbound catches first light on Mother Cline, turning the slide path orange-pink as the sun clears the ridge, and the turnout faces east so you don’t shoot directly into glare.
Q: May I fly a drone over the avalanche paths?
A: Only if you follow FAA Part 107 rules, stay below 122 m (400 ft), keep the drone out of designated wilderness to the west, and avoid takeoffs from highway pavement; Rangers do ticket unpermitted flights, so check San Juan National Forest regulations first.
Q: Are the scars visible year-round?
A: Yes, even when snow melts the bare earth remains exposed, so you’ll see the brown ribbons in midsummer greenery, in autumn gold, and outlined in fresh snow come early winter.
Q: Why do people call Highway 550 the “Million Dollar Highway”?
A: Legends clash—some say the fill dirt held a million dollars in gold ore; others claim the original 1920s rebuild cost a million dollars per mile; everyone agrees the views feel priceless, hence the catchy name.
Q: What’s the cheapest way to reach the pass without a car?
A: Hop the Bustang Outrider bus from Durango to Silverton for about USD 20, then walk the sidewalk loop to Overlook #1 or book a USD 45 afternoon shuttle tour that climbs the remaining nine miles to the summit.
Q: Which avalanche paths actually hit the road in winter and how is safety managed?
A: Mother Cline, Blue Point, and Blue Willow can run full length to the pavement, so CDOT closes gates at dawn and fires remote Gazex or O’Bellx cannons to release smaller, controlled slides before reopening the highway.
Q: Where can experienced backcountry skiers start a safe skin track without trespassing?
A: Gate 3 north of the summit offers legal parking and access to tree-gladed slopes under 30 degrees; always carry beacon, shovel, and probe, and check the Colorado Avalanche Information Center forecast before leaving the lot.
Q: Is there avalanche education available in Durango?
A: Yes, the Friends of the San Juans host evening AIARE awareness talks and weekend Level 1 courses, and Junction West guests get a small tuition discount when they show a current reservation.
Q: Can we loop the pass, soak in Ouray’s hot springs, and still be back for a riverside campfire?
A: Absolutely—drive north over the pass, spend two relaxed hours in the Ouray Pool, grab an early dinner, and you’ll still make the 2-hour scenic return to Junction West before the stars and s’mores appear.
Q: Will my phone or hotspot work on the pass?
A: Expect strong 4G in Silverton and Ouray, spotty bars on the summit, and long dead zones along the cliffs, so download maps and upload photos before you leave town or wait until you’re back at the resort’s reliable Wi-Fi.
Q: Where’s a quiet picnic spot with a romantic view of the scars?
A: The unsigned turnout at milepost 87.3 has room for one or two cars, a flat ledge overlooking Irving Gulch, and just enough shoulder to unroll a blanket, making it perfect for a peaceful toast at golden hour.
