Backpacked into Lower Ice Lake Basin at 11,400 feet, hiked Vermilion the next day, then hiked out that same day.
The hike from camp to Vermilion took me a little over 4 hours. The last couple hundred feet to Vermilion was a bit hairy, with a couple of steep, loose gullies. The last 20-foot walk to the summit was a narrow and exposed ridge.
Backpacked into lower Bilk Basin at 11,000 feet, hiked Gladstone the next day, camped another night, and hiked out the 3rd day.
The hike from camp to Gladstone and back to camp took 10 hours. The ridge to Gladstone took 2 hours up, and almost 2 hours down. It was a steady Class 4 ridge scramble.
I made a number of route-finding errors, but none significant.
Missed reaching the summit by about 700'. My little dog Jax was simply wore out by the technically challenging trail. Also, we were off-trail on the ascent to Rock of Ages saddle, mistakenly making a much steeper, more demanding hike to this point.
Anyone using this route should note that the trailhead is different from Roach's. Mine is correct. Roach's trailhead no longer exists.
