About this trail
Pioneer (USFS trail 1149.1B) is a 2 mi trail in Medicine Bow-Routt National Forest, Colorado. This profile summarizes what the official US Forest Service trail record says about riding it: how long the trail is, what it's built on, how steep the route grades out, and which forms of bike use the agency has designated. USFS records list its surface as native material. USFS slope data puts it in the Advanced band (grade band 12-20%), meaning a steep climb — keep in mind this measures steepness, not trail technicality. For traditional mountain bikes, use is discouraged according to USFS data. The record additionally permits Class 1, Class 2, Class 3 e-bike use, Jun–Dec; recall that Class 1 is pedal-assist, while Class 2 adds a throttle and Class 3 a higher cutoff speed. 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. For day-of certainty on closures or seasonal orders, check directly with the ranger district, since this reflects the USFS data as of the latest refresh.

How we read this data
Grade-based difficulty above is the USFS grade (route steepness), not a technical mountain-bike rating — a gentle-grade trail can still be rocky or technical, and vice versa. Bike and e-bike status come verbatim from the USFS managed-use fields for this trail; we never infer access we can't cite. See our methodology for how the dataset is built and what each field means.
