About this trail
Calaveras Dm Ohv 4x4 Rt4c (USFS trail 17EV151) runs 2.5 mi through Stanislaus National Forest in California. 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. The tread is mapped 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. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (Apr–Dec) — Class 1 being pedal-assist only, Classes 2 and 3 adding a throttle and higher assisted 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.
