About this trail
Mapleton-Sawmill Hollow (USFS trail 8013) is a 12.7 mi trail in Uinta-Wasatch-Cache National Forest, Utah. The figures here are pulled from the official US Forest Service trail data for Uinta-Wasatch-Cache National Forest, covering the trail's mileage, tread, grade band, and the bike and e-bike uses the agency lists as designated. The tread is mapped as native material. Based on slope, this is a Intermediate trail (grade band +10-12%); that reflects moderate gradient and is not the same as a technical MTB difficulty rating. Mountain bikes are allowed, with a Jun–Oct season in the data. The record additionally permits Class 1, Class 2, Class 3 e-bike use; 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 2 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.
