I took my annual fall trip to Yellowstone. I was gone 2 weeks. Lori was with me for the first week, and when she left Fran joined me along with Greg Chandler for 3 days. I spent the remainder there by myself. Weather was great and wildlife watching was the best ever.
Next, Lori and I went to the Midway Geyser Basin. Excelsior Geyser and Grand Prismatic Spring were as beautiful as ever. On the way back to the parking lot I took a few shots of the bacterial mats around the outflow from Excelsior Geyser.
