The precipitation didn't start until we passed West Thumb, but before that it was gusty head-winds. The notification sign at the junction sound of Lander had "South Pass 50+mph winds".
But it wasn't wet when we went out for the first One Burst Grand of the year. The sun was actually trying to come out. The first geyser I saw was the end of a Tilt eruption. But the interesting thing was that Crystal Spring and Belgian Pool were down about 3cm, and that was higher than earlier. At the same time Slurp was having a wet steam phase eruption-- lots of wet droplets with a hint of the slurping sound.
On the way back, we did get to see the mule deer and bison who have been hanging around together. They were in the trees over by Oval Spring.
