Shoshone Geyser Basin, Yellow Crater Group

By leaving the North Group to the north you also leave the area of significant geyser activity behind you. The Yellow Crater Group comprises mainly small features which are no more than wet holes in the ground. However, there are a few exceptions. One of the first to come across is Blowout Pool, the only clear blue pool of size within the group. Even more interesting than the pool is the feature east of it. Similar to Five Crater Spring it consists of a pool covered by a sinter ledge. The sinter is perforated at three spots, where the boiling spring squeezes out small water jets. Further splashes can be seen near the east and west edges of the sinter ledge. The whole setting reminds a pressure cooker with a leaking lid. Obviously, the activity is intermittent, just as known from Five Crater Spring.
