We are back from a weeklong hiking vacation to Yellowstone to celebrate Doc’s 15th anniversary (and congratulatory sabbatical month) with REI. We took a guided REI Adventures trip and got a thorough view of the park, ate at all the different lodges, saw lots of wildlife (not shown: moose, marmot, elk, pronghorn, and fresh bear scat!), and hiked at least 5 miles a day. Hang on, there are lots of pictures:

Abyss Pool

Grand Canyon of the Yellowstone

Grand Prismatic Spring

Forest at the base of Avalanche Peak

Sagebrush highlands on the way to Trout Lake

Yellowstone Lake from Lake Lodge

Jackson Lake from Signal Mountain Lodge and a new word (?)

Bison doing their thing. The rut was already on and it felt like fall up there.

Trout Lake

Wolf sighting! We saw three from maybe 50 yards away! Definitely the highlight of the trip.
