Sunny day in Mammoth today. Sightings along the Beaver Ponds Trail were bison, elk, a skunk, bluebirds, flickers, killdeer, juncos, chickadees, and WILDFLOWERS! The signs of spring are starting to show.
While bears and marmots are fast asleep during the winter, martens (and other members of the weasel family) are busy hunting every day for enough calories to stay warm. Seeing one is a rare treat. Getting one to stay still long enough to take a photo, that's a different story!
Love the stunning colors of John Day Fossil Beds National Monument. Reminds us of peering into the Grand Canyon of the Yellowstone.
The sunset is getting close to 8pm these days. Anyone else besides us enjoying the extra daylight?

This week in 1894, scout Felix Burgess captured notorious poacher Ed Howell skinning bison hides inside Yellowstone. Stories about Howell’s arrest were picked up by the national press. The public outcry that followed led to the Lacey Act of 1894, which formally protected the wildlife in Yellowstone from hunting. Today a healthy population of bison live in the park: the largest on public land...
