Last weekend I went on my first multiday backpack, 3 nights near Green Lakes in the Three Sisters Wilderness. Also my first time in the area, it was quite nice! Broken top is about 300,000 years old, but the Three Sisters are all about 50,000 years old, plus there's lots of little old lava flows spilling out all over the place. The USGS says there are 466 distinct volcanoes of age under about 3 million years in the area.

The first day, we went #hiking up Broken Top. The views of a huge line of Cascade Volcanoes were quite nice! Also lots of butterflies, including a swarm of California Tortoiseshell butterflies near the top, and several Ceanothus Silkmoths lying still on the trail. Apparently these only live a week or two once emerging from their cocoon, because they do not emerge with functional mouths! Seems like a raw deal.
