Thanks to Ralph Taylor for first posting info about the eruption of "Wall Pool" on the evening of July 13, 2006, and then to Kendall Madsen for the further information and photo showing the eruption. I placed the name in quotes because upon consideration, I believe this feature needs some sort of individual designation. >From Whittlesey's _Wonderland Nomenclature..._ is this: "Prior to the 1959 Yellowstone earthquake, geologist George Marler was not sure whether or not Wall Pool (named by Marler before 1959) had a water source of its own or whether it was merely a collecting basin for other springs. Its name was given from the wall-like escarpment which forms it southwestern side." Furthermore, a close look at my copy of the USGS thermal map shows a curved arrow pointing away from the written name toward the northwestern-most part of the spring immediately adjacent to the "wall" that surrounds its west and southwest sides. The July 13 eruption took place from a separate feature that is closer to Black Opal Pool than it is to the map-indicated Wall Pool. I am not proposing a name here, but I think it needs one... as I think the "new thing near the river" also needs a name (some of its bursts today probably reached 6 feet high).
