I'd always wanted to ski out to Fairy Falls, but we'd never done that. So we did. We got a ski drop to the trail head along the Firehole River.
Fairy Falls was a mix of frozen ice features and flowing water. Really nice. I took out my camera to take a snapshot and it didn't work - the battery needed to be recharged. I forgot that I had my GoPro in my pack. If I'd remembered the GoPro, I'd have a photo. Oh well.
On the way back we walked up to the overlook at Grand Prismatic Spring. Last time we were on the trail the overlook was closed. At the overlook I remembered I had my GoPro and I got a couple of wide angle snapshots of the view.
On the way back Mary spotted some fresh coyote tracks. The coyotes often follow the ski trails and it was fun to see how the coyote used the ski trail. Then after we crossed the river, we spotted the coyote that had just left those tracks.
The trail back to the geyser basin follows a power line. Along that trail we encountered a large bison. We made sure the bison saw us to see if that would encourage him to move. It didn't. We waited a while. The bison didn't move, just stood on the trail and kept eating. Eventually, we decided to get down to the road. That meant cutting off trail through deep snow. We reached the road, went a bit to get by the bison, and then cut back to the trail at a point where it was relatively near the road. That meant more deep snow - a tiring chore.
On the way back we stopped at Black Sand Pool. One of my two or three favorite thermal features. We hung out a little bit, but it was a bit chilly with the wind.
