About this trail
In Superior National Forest, Minnesota, Kawishiwi Triangle Birch Lake (USFS trail 51195B SNOW) covers 0.8 mi of National Forest System trail. The figures here are pulled from the official US Forest Service trail data for Superior 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. USFS slope data puts it in the Easy band (grade band +0-5%), meaning a gentle climb — keep in mind this measures steepness, not trail technicality. Bike use is designated as allowed, typically Jan–Mar, December. 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 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.
