Trail Information

Highlights

Topaz Mountain and Wallace Gulch 4x4 trails wind their way up through the forested hillsides of North Tarryall Peak and Topaz Mountain on the south side of Lost Park near Jefferson, Colorado from Lost Creek to an altitude just over 11,300 feet and back down again. As you pass through the pine, fur and spruce forests punctuated by gorgeous green meadows, you are treated to occasional glimpses of the peaks of the Lost Creek Wilderness Area north and east, across the valley. On the way down Wallace Gulch, back toward Lost Creek, you encounter a relic of a bygone era as you come across the rusting carcass of an old pickup truck. Wildflowers are abundant in the spring and early summer while changing aspen grace the view in the fall. There are many opportunities for camping making this a great place for a peaceful weekend get-a-way.

Calvary 4-Wheelers ran Topaz Mountain-Wallace Gulch as part of our End of the Season trip on Saturday, November 4. Along for the trip were me in my mildly modified Wrangler Unlimited (LJ), and Ali in his stock Chevy Silverado ZR2. The day was bright and sunny with mild temperatures in the upper 40s to low 50s and only a light breeze. After a small mud puddle and a clear patch around the corner, we entered the trees where we found 4-6 inches of snow with a few places here and there that were drifted deeper and a few that were windswept or melted. The snow added just enough difficulty to make it interesting but not enough that we struggled. The forest was beautiful and peaceful in the snow and the sunlight made it sparkle like a million diamonds. We followed tracks to a spot between Waypoints 4 and 5 where whoever made the tracks turned around. From there until Waypoint 8 the only tracks were some old side-by-side tracks that were drifted over so we were essentially breaking trail. After the intersection with Bonis Creek, there were tracks again the rest of the way. We did notice that the old truck at Waypoint 10 is gone.

My new favorite mellow trail close to home! Can’t believe I waited so long to come here… virtually no one up on the trail. Scenic, peaceful and a true joy to ride on.

Great run. Had one person that we had to pass on the narrowest section. Great to have met these folks, we worked together to pass with about an inch to spare.
