About this trail
In Apache-Sitgreaves National Forests, Arizona, Aker Lake (USFS trail 17) covers 4.9 mi of National Forest System trail. The figures here are pulled from the official US Forest Service trail data for Apache-Sitgreaves National Forests, 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. Its grade-based difficulty is Advanced (grade band +12-20%) — a steep steepness profile derived from USFS slope data, not a technical mountain-bike rating. Bike use is designated as allowed year-round. The agency lists no Class 1, 2 or 3 e-bike designation here; absent a local order to the contrary, that means e-bikes are not an allowed use on this trail. The route is mapped as USFS Trail Class 4 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.
