Straight-line distances. Driving routes are longer; many refuge roads are gravel and may close seasonally.

The navigation point is a point inside the unit polygon, not necessarily a parking area or legal access point. Use satellite view to find roads, gates and designated parking, and respect closed areas and private inholdings.
