Ascent Trip Report

i started out just climbing up the ski hill... which is pretty steep, covered in deep dry grass, and i ended up flicking 4 ticks off my arms as i climbed. there's no good reason to do this, there's a perfectly good road with switchbacks to the north of where i started. i eventually intersected with the road, and followed it a couple switchbacks when i was tempted by an obviously abandoned old road segment. i took that, and unfortunately it ran into a plastic fence, where i headed straight uphill again for a while, before finally giving in and cutting back to the maintained road/switchbacks. about the only good thing about the places i was climbing uphill was the shade of the trees.

when i reached the ski patrol hut at the top i wasn't sure where the trail was, but i went around to the north side and started climbing uphill from there. i would eventually find braided use trails. along these use trails are one or two zip lines (i think it's two, but on the way down it looked different and i didn't double-check if it was the same zip line as i saw on the way up). no idea if they're safe: i wasn't going to take that chance!

basically the crux is between the ski patrol hut and skyline peak: it's just a steep wooded hill. fortunately it's not a bushwhack though, the understory is quite manageable.

skyline peak has good views to the north, easily tagged as a (not prominent) bonus. from there to bonneville is an easy ridge hike, although at this time of the year i ended up with many burrs on my pants.

i couldn't find a register at the summit... i checked both at the cairn, and at the tree covered bump which seems to be slightly higher than the cairn.

great views, and quite pleasant temperature up top, despite the approx. 90F in the valley.

on the way down, while i was still fairly high up on the road, i bumped into what i assume was a wedding party, having photos taken. i assumed they must have permission to drive up... but as i continued down i saw no vehicle. their footwear (and lack of sweat on their dressy clothes) made me skeptical they had climbed the road. i couldn't figure out how they got there until i was almost at the bottom: when the operators started one of the chair lifts. it had been otherwise idle while i was hiking... i don't know if the lifts are available in general, or if it was just a special case.
