Today I had to conduct several environmental trainings around the park, so I drove most of what's referred to as the Grand Loop (except for the Beartooth Pass which is still closed). I welcome long drives in Yellowstone as there is always something interesting to see. Baby bison greeted me in the morning, and a few minutes later I watched a grizzly bear--his paw hurt from an encounter with a porcupine--foraging in a meadow.

As I drove into the park's interior, I also moved into winter. A blanket of snow still covers Hayden Valley and Yellowstone Lake's smooth, frozen surface shows not even a hint of blue water. I also made sure to catch an eruption of Old Faithful--it never fails to elicit a child-like delight in me even though I've seen it erupt dozens of times. Visit the live streaming webcam of Old Faithful to watch it remotely. I waved hello and said happy Mother's Day to my mom in Massachusetts on the webcam today.

I've posted a selection of photographs and videos below from my Yellowstone field trip.
