Yellowstone National Park, which straddles the borders of Idaho and Montana but is mostly in Wyoming, is famously on top of an underground “supervolcano.” The volcanism in the area leads to the phenomenon that Yellowstone might be most famous for, namely Old Faithful geyser and many smaller and less faithful geysers.
Yellowstone also boasts these surreal-looking mineral pools. The edges are white, crusty mineral deposits similar to Tolkien’s descriptions of Mordor. The colors within the water come from heat-loving bacteria. Different microbes thrive at different temperatures, and they are responsible for the range of reds, oranges, and yellows before the water becomes clear and hence blue.
These pools are dangerous. They look appealing, but the heat will quickly kill any human or dog foolish enough to jump into one. There have been tragic cases at the park. Some people have survived their burns and others haven’t. To make matters worse, the ground around the pools can be fragile although it appears solid. The park has put up boardwalks studded with signs imploring people to stay on the paths and keep control of their children. Even the bison sometimes break through.
The landscape around these pools is not particularly beautiful, but it is interesting, even alien. I happen to have at least one pleasant association with the Mammoth Hot Springs area of Yellowstone. It was there that my now-husband first blurted out that he loved me.
However, in my book The Strange Land, my characters’ encounter with these pools did not go so well.
The strange land of the title is not Yellowstone National Park. It is another volcanic region, the area now known as Kamchatka. Kamchatka also has sulfurous pools. Behold:
For my second draft for a cover of The Strange Land, I thought about featuring one of these pools, with the volcano in the background:
I’m not sure how I feel about this cover painting. For one thing, there’s a lot going on in it. I’m not sure it has enough focus. For another, it’s kind of hard to believe. The colorful pool, the colorful vegetation, the white mineral deposits: all of them are well attested, but they look kind of … made up? I’m not even sure it would be clear what the pool is, to a viewer who wasn’t already familiar with Yellowstone.
I’m thinking perhaps I need to re-do this picture with a darker sky and with slightly more muted colors in the pool. You know, tone it down from real life to make it more believable.
For reference, the previous cover draft for the same book was this:
