About this trail
Kawishiwi Triangle Iron Birch (USFS trail 51195 SNOW) runs 2.7 mi through Superior National Forest in Minnesota. 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. The tread is mapped as snow. Its grade-based difficulty is Easy (grade band +0-5%) — a gentle steepness profile derived from USFS slope data, not a technical mountain-bike rating. Bike use is designated as allowed, typically Jan–Mar, December. 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 Superior 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.
