The boundaries of Grasslands National Park appear wrong. Both the park website <https://www.pc.gc.ca/en/pn-np/sk/grasslands/visit/visit9/d> and Google Streetview indicate the road enters the park here, right where OSM has the surface worsen, but OSM shows the east unit as being smaller and further north, covering the Rock Creek entrance but not the Badlands Viewpoint entrance

This is wrong. There is no trail here. I tried to delete it in the editor, but it won't let me because not the entire trail is visible in the window, but when I zoom out far enough to see it it fails. It considers the full route of E1 through Børgefjell.
