Today we put on all the layers that we had and we went for a three hour walk around the Upper Geyser basin in 3 degree weather. It did warm up to 10 by the time we were finished and we were actually a bit warm by then – we had both forgotten that you actually can dress for cold weather and enjoy the outdoors. The view is amazing with all of the steam rising everywhere you look. It is also cool to see the “ghost trees” which is what they call the trees that are all frosted because of the steam that comes from the geysers (2nd picture).
The loop that we took had 12 geysers and many, many hot spring pools. To be honest with you we cannot remember which ones are which, but we do know that the 9th picture is Morning Glory pool and the 10th picture is Grotto Geyser (which was very cool because it constantly erupts – small eruptions, but eruptions none the less).
The highlight of the day was seeing Castle Geyser erupt (last 5 pictures). It was supposed to erupt at 3:00, +/- 45 minutes. So, we went out there at 2:10. It erupted at 3:42. It was well worth the wait though. It shoots water up in the air for 20 minutes and then shoots steam up in the air for 20 more. The sun was just right during the steam phase and it made a beautiful rainbow. It actually puts Old Faithful to shame as far as the show is concerned, but it erupts far less often.
