I did the alternate route starting on Clamshell Truck Trail, then up the firebreak. I underestimated the effort and water required for this hike. 2450' gain in the last two miles. Trail degenerates to animal trails about half way, went a little ways down the wrong ridge on the way back and ran out of water. Tough little peak.

Up and OMG UP
Pink metal marker after the first steep section, no benchmark, no signs
Thanks for the report. I was wandering around up there a couple years ago and couldn't find the register. Maybe I should pay more attention to forums like this.
