There were so many incredible attractions to see and not very much time to see them. On our last day we decided to stop at Upper Geyser Basin. While driving along the Madison River we saw a grazing buffalo very close to the road and also a family of buffaloes with two red dogs trotting alongside the road. The buffaloes surrounded their calves, as they usually do, to protect them.
The view of the basin was somewhat surreal. White steamy smoke was rising from the surface in many places, accentuated by the dark woods in the background. We started hiking to the famous Morning Glory Pool, but the trail went through a thick wooded area. We did not have bear spray with us and decided to turn back. A wooden bridge across the swift flowing Firehole River had a great view of the river banks covered with tiny yellow spring flowers and fir trees. White steam was rising from the barren spots created by hot runoff water from hot springs.
Biscuit Basin has a boardwalk loop trail, which is less than a mile. However, there were many jewels of nature to see. The first one was Black Opal Spring. Its azure surface was covered with a milky cloud of steam. Next to it was Wall Pool and a few other pools all exuding thick cloudy cover.
Then, we approached Sapphire Pool, the crown jewel of Biscuit Basin. The color of its water is true to the color of the gem stone it was named after. The temperature of the pool is about 200 degrees Fahrenheit and its size is about 18 to 30 feet, the largest in the basin. Biscuit Basin got its name from the peculiar deposits which used to be around Sapphire pool, which looked like biscuits. In 1959, after an earthquake in Yellowstone, Sapphire Pool erupted and blew away the deposits. So, you won’t see biscuits of any kind in the basin.
We followed the boardwalk clockwise and passed Jewel Geyser, which was dormant at that time except for its steaming breath. Shell Geyser was boiling and looked very lively. Avoca Spring was not active at the time but steam was rising from its crater. Mustard Spring got its name because of the mustard colored deposits around the crater.
It was our last day in Yellowstone. We saw so many wonders of nature and wildlife during our visit to Yellowstone that we will never forget Yellowstone’s beauty, wilderness and inexplicable geothermal depth from the heart of the Earth. There are many interesting things that we missed in the park. It entices us to come back. Until next time, good buy Yellowstone!
