Black Pool of West Thumb Geyser Basin
|Colors and Textures of Black Pool|
My favorite feature from this area is Black Pool. The orange-red bacterial mattes are outstanding and so close to the lovely blue depths of the pool. You really can get up-close and personal with this feature. The colors are similar to Grand Prismatic Spring but on a smaller scale. I tried to capture the fine detail and contrasting colors in this photograph.
Black Pool is no longer black. A couple decades ago the temperature changed, colors changed but the name remains the same.
