Borah Peak in Idaho sounds like quite a challenging trip for a day hike even though it is only Six miles round trip.. It can be done without technical equipment but
Quote:
I offer the following as recommendations for minimal preparation beyond adequate snacks, water and clothing: (a) good physical condition, (b)acclimation to high altitude, (c) absolutely no tendency for vertigo, (d)experience and confidence in scramble-climbing while wearing a backpack,(e) ice ax, with experience in arresting a glissade on extremely steep slopes, and (f) a very early start, to avoid lightning on the exposed slopes. If there is snow besides the permanent snowbank in the high altitude notch, climbers should have (g) crampons, and (by Zumwalt's recommendation) be (h) roped, with experience in arresting the fall of a companion. (i) Zumwalt also notes that "the final assault involves ascending finely-balanced loose rock, and the hazard of falling rock makes a hard hat advisable."
Here's a report.
