Frequently Asked Questions
🚇 🗺️ Getting There
The Slumgullion Earthflow is located along Colorado State Highway 149 (CO-149) between Lake City and Creede, Colorado. It's easily accessible by car, with numerous pull-offs and overlooks directly off the highway. The drive itself is scenic, part of the Silver Thread Scenic Byway.
CO-149 is generally open year-round, but winter conditions can lead to temporary closures or require 4WD/chains. It's always best to check road conditions with CDOT before your trip, especially outside of the summer months.
The closest towns are Lake City to the north and Creede to the south. Both offer lodging, dining, and other visitor services. Lake City is about 15 miles north, and Creede is about 25 miles south of the main earthflow area.
Yes, RVs can access the Slumgullion Earthflow via CO-149. The highway is paved and well-maintained. However, be mindful of the numerous pull-offs and ensure you have adequate space to maneuver if you plan to stop.
No, there is no public transportation that directly serves the Slumgullion Earthflow. A personal vehicle is necessary to visit this natural attraction.
🎫 🎫 Tickets & Entry
No, there are no entrance fees or tickets required to visit the Slumgullion Earthflow. It is a roadside natural attraction managed by the U.S. Forest Service, and access to the overlooks is free.
The Slumgullion Earthflow is accessible 24/7, as it is an outdoor natural feature along a public highway. However, daylight hours are recommended for the best viewing experience and safety.
Facilities are very limited. You'll find basic informational signage at some overlooks and vault toilets at a few designated rest areas. There are no visitor centers, gift shops, or restaurants directly at the earthflow.
While you can walk around the immediate areas near the overlooks, extensive hiking directly on the unstable earthflow is not recommended for safety reasons. Stick to designated paths and viewing areas.
Some of the main overlooks have paved paths and are relatively accessible. However, the terrain is inherently uneven, and exploring further afield may be challenging for those with mobility issues.
📸 📸 Photography
The numerous pull-offs along CO-149 offer excellent vantage points. The main overlook provides a sweeping panorama. For unique shots, explore the edges of the earthflow (safely!) to capture the texture and scale. Early morning and late afternoon light create dramatic shadows and highlight the terrain's features.
A wide-angle lens is great for capturing the vastness of the earthflow. A telephoto lens can be useful for isolating interesting rock formations or distant mountain peaks. A tripod can help with low-light photography during sunrise or sunset. Don't forget extra batteries, as cold weather can drain them faster.
Drone usage is subject to U.S. Forest Service regulations. Generally, drones are permitted for recreational use in many areas, but you must follow FAA guidelines and avoid flying over people or sensitive wildlife areas. Check with the nearest Forest Service office for specific restrictions.
The 'golden hours' – shortly after sunrise and before sunset – offer the most dramatic lighting. The low-angle sun casts long shadows, accentuating the earthflow's contours and textures. Midday sun can be harsh and wash out details.
Yes, the Pioneer Cabin is a popular subject for photographers. It offers a glimpse into the past against the backdrop of the immense earthflow. Be respectful of the historical structure.

Understanding the Slumgullion Earthflow
Geologists study the earthflow to understand the processes of mass wasting and the stability of volcanic slopes. The varied textures and sizes of the rocks and soil within the flow provide clues about the forces involved in its creation. The landscape is a chaotic jumble of hummocks, depressions, and channels, a testament to the immense power of nature. The earthflow has significantly altered the local topography, damming drainages and creating unique microhabitats.
Visitors can best appreciate the scale of the Slumgullion Earthflow from the numerous overlooks along CO-149. These viewpoints allow you to grasp the immense breadth and depth of the ancient slide. It's a powerful reminder of the dynamic geological forces that shape our planet.
Exploring the Silver Thread Scenic Byway
Driving the Silver Thread is an experience in itself. The road climbs to over 11,000 feet at Slumgullion Pass, providing breathtaking vistas. Along the route, you'll encounter opportunities for hiking, fishing, and exploring the rich mining history of the region. The contrast between the rugged, raw beauty of the earthflow and the charming, historic towns makes for a memorable road trip.
When planning your visit to the Slumgullion Earthflow, consider dedicating time to explore the entire Silver Thread Scenic Byway. This will allow you to fully appreciate the natural and historical wonders of southwestern Colorado. The byway is particularly stunning in the fall when the aspen trees turn vibrant shades of gold and orange.
