About this trail
In Allegheny National Forest, Pennsylvania, Snow Timberline Warmup (USFS trail SNO85026W) covers 3.6 mi of National Forest System trail. The figures here are pulled from the official US Forest Service trail data for Allegheny National Forest, covering the trail's mileage, tread, grade band, and the bike and e-bike uses the agency lists as designated. Underfoot, the trail is recorded as snow. No grade band is recorded, so a steepness-based difficulty isn't available for this trail. Note that mountain-bike use here is not designated in USFS records — confirm with the ranger district before riding. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (Jan–Apr, December) — 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 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. Treat this as a planning reference rather than a live conditions report, and verify any time-sensitive closure or order with the ranger district that manages Allegheny National Forest.

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.
