Leaving directly south from the Thompson Lookout, the Thompson rim trail undulates along the Skimmerhorn ridgeline. Gnarly Balsam Fir and Whitebark Pine dot sub-alpine meadows home to Mariposa Lily, Mountain Harebell, Spike-like Goldenrod and Sub-alpine Daisy. Eastward Views over Russell Creek are visible from a natural rocky gateway and continue to the first short climb through a bit of scree and dense Balsam. Reaching height of land, expect to see down over Thompsons alpine rockfall and over the city of Creston. The ridgeline descends and then climbs, following cairns over a short scree section before reaching the trails end at a repeater station. Panoramic views abound, from here you can see West over the Selkirks, North into the Purcells, East to Yahk and Moyie and South into Northern Idaho.
