Ptarmigan Peak位在Silverthorne附近,橫跨Summit County和Grand County兩郡,海拔12,490呎/3,807公尺,山頂有360度的展望,舉凡Dillon Ranger District範圍內的每一座山頭都一覽無遺。
上週六登山隊前往Silverthorne經由Ptarmigan Peak Trail攀登該山,該山前幾年曾跟登山隊去過三次,一次由Angler Mountain Trailhead起登後併入Ptarmigan Peak Trail,兩次由Ptarmigan Peak Trailhead起登,其中兩次均僅登抵海拔約11,500呎/3,505公尺後下撤未登上Ptarmigan Peak,僅2019年10月05日才登上Ptarmigan Peak山頂,此次登頂算是第二次登頂。
