Botryoidal Spring is off in the field to the right as you walk towards Octopus Spring from the parking lot. The eruptions are short (less than a minute) but frequent (every few minutes), so it’s easy to capture if you know to look for it.
Attendance must be up at the park, because this backcountry pool now has a little fence on the ground in front of it. Not a bad idea, but now you can’t get a picture without it. I have to admit that there’s not a lot of space between the pool and the hillside. I have some photos where it looks like people are way too close to this feature. That isn’t the case, but if the pool is between you and the person and you zoom in, it looks like the person is standing right on the edge.
A nice pool in West Thumb.
