At sometime around 20:00 today (Thursday 13 July) Wall Pool in Biscuit Basin had an eruption. Kendall Madsen saw the eruption from the parking lot while returning from the Artemisia trailhead, and managed to get a photo from the parking lot. By the time other gazers arrived the activity was over. The eruption was on the northwest side of the large pool (the one past the small pool adjacent to the walk with the "Wall Pool" sign. Some rather large chunks of what looked in the evening light to be mud were scattered around the far (north) side of the pool, and muddy water was making its way through the pools down to the Firehole river. -------------- next part -------------- A non-text attachment was scrubbed...
