Here is a table Pete and VersatileFred created in another location: Note: This trail-video-documenting was done a few years ago at the end of October (just before the first arrival of snow), and under most favorable weather conditions without any wind and no snow or ice on the trail, except for some ice at the cables. The video makes it look easy, but high altitude and inclement weather could make it a tough and very long 22 mile (round-trip) hike.
