When in Yellowstone one must make photographs of the geothermal features. Here are mine!
The microbial mats around the geothermal features are a source of constant fascination to this retired biochemist.
TAC polymerase which makes the polymerase chain reaction (PCR) possible was isolated from Thermus aquaticus, a bacterium that lives in hot springs. Possibly, this fact is the source of my interest in these mats.

We also spent a very cloudy drab afternoon in Grand Teton NP. The afternoon included a stop at the overlook where Ansel Adams’ well know photograph titled “The Tetons – Snake River” was made; the view has changed much since 1941-1942.

Well, the Yellowstone images brought back fond memories. I enjoyed shooting the very colorful geyser pools, etc.
