Over the past 2 million years there have been 3 volcano eruptions in the Yellowstone Park area shaping and creating the geothermal features that the park is noted for. Instead of getting caught up in the rush of people who usually enter the park mid morning, we left our RV at 7 a.m. and headed for the Granddaddy of all geothermal features, Old Faithful. On the way, we just couldn’t resist stopping at Beryl Spring. The early morning cold temperature and heat coming from the cracks in the earth made it look like something out of a horror movie.

We arrived at Old Faithful in plenty of time to get front row seats to have a perfect picture position. We had to wait over an hour, but it was worth it. There were at least four false starts, and then we knew the real thing was coming. Without having something to give you perspective, there is no way to show the size and power of this gushing water spewing into the air.

The next stop in the Caldera (what they call the volcano area) was Midway Geyser Basin. The pictures get progressively more impressive.

The West Thumb off of Yellowstone Lake had more to see.

This Mud Volcano area was really different than any other area we saw today. The last volcanic eruption was 664,000 years ago and had a force 1000 times greater than Mount St. Helen. The entire Caldera area is sitting over the volcano which provides the immense heat.

In 1995 there were 500 earthquakes that increased the temperature in this mud pool from 150 degrees to 170 degrees. This looked like a giant pot of mud boiling on a stove. Pretty impressive photography for a amateur to get the bubble just as it flared.
We only spent a short time at Mammoth Springs. We had started out early and I was beginning to feel my injury so we only drove the upper terrace where we took these pictures.

Tomorrow we have to leave Yellowstone and we are going to Buffalo, Wyoming to an RV Park that can accommodate us for 6 days. Its a small town with a population around 4,400 and nothing to see or do, so we will just be sitting around relaxing with nothing interesting to write, we hope.
