About this trail
Boss Lake/Cdnst (USFS trail 1419) is a 1.2 mi trail in Pike and San Isabel National Forests, Colorado. The figures here are pulled from the official US Forest Service trail data for Pike and San Isabel National Forests, 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 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. Bike use is designated as allowed year-round. No e-bike class (1, 2 or 3) is designated on this trail in the USFS data, so treat it as a non-motorized route unless a posted order says otherwise. 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. 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 Pike and San Isabel National Forests.

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.
