About this trail
In Grand Mesa, Uncompahgre and Gunnison National Forests, Colorado, Elk Run Loop Snow (USFS trail 6S128.E) covers 2.8 mi of National Forest System trail. Everything below comes straight from the US Forest Service National Forest System Trails dataset — length, surface, slope-derived difficulty, and the specific bike and e-bike designations on record — so you can check legality before you load up. USFS records list its surface as snow. Based on slope, this is a Easy trail (grade band 0-5%); that reflects gentle gradient and is not the same as a technical MTB difficulty rating. Bike use is designated as allowed, typically Jan–May, December. The agency lists no Class 1, 2 or 3 e-bike designation here; absent a local order to the contrary, that means e-bikes are not an allowed use on this trail. The route is mapped as USFS Trail Class 3 on the agency's 1-to-5 development scale, where 1 is the most primitive, minimally maintained tread and 5 is the most developed. Because conditions, closures, and local orders change between data refreshes, confirm the current status with the managing ranger district before you ride.
