From Excelsior/Center col, I started the ascent of 2nd peak of the day. Slogging up Center Mountain was easier than I thought. The lower slope was good snow. Boulders didn't come until I was 2/3 of the way up. There were several rock crevasses near the summit. They weren't completely covered by snow though, but this really alerted me. I did make a lot of probing though. If you don't probe, you'll get surprised often, and possibly break your legs or twist your ankles... The traverse from Excelsior to Center took me 1.5 hours.
The summit view was still awesome, but given the fact I had just bagged Excelsior Mountain, the views were a bit repeating.
The connecting ridge to Amber Mountain didn't look inviting though. It's not because of the difficulty, I just didn't want to deal with another 2 hours of boulders.. I knew the Skyline Trail leads up to Amber, so maybe following the trail was a better option, although this way I had to drop down to valley floor. I descended the north ridge for a few hundred meters, and then turned skier's left and got several hundred meters of scree run! Thanks! But the terrain soon changed to boulder field again... It was pretty close to the bottom anyway, and I quickly made my way down.
