Summit:
W7O/NE-223
If you find yourself on US-26 at Dixie Summit (the pass), just east of Prairie City, you could activate Dixie Butte, http://www.pnwsota.org/blog/k7atn/2018-november-25/dixie-butte-or-june-2017, with your high clearance vehicle, or you could park your Prius and bushwhack 1.5 miles RT and 550 ft. of elevation gain to 5784.
