Mammoth Cave, Idaho

Yesterday our good friends Linda and Dale took Barbara and I for a drive to visit the Mammoth Cave in Idaho. This actually isn’t a cave at all. It’s actually a lava tube. Well me being a geologist I’m always interested in caves, lava tubes, anything thing that is geology related. Now most people believe that lava tubes are pretty much devoid of life, but as I will show you in my photos below there is a lot of life inside. Most caves and lava tubes make good homes for bats and this lava tube is no exception. This lava tube is home to a bat that weighs approximately one once and had a wing span of 6-inches. They are great for controlling insects inside.

Also here is a bird sanctuary and museum. The museum is especially interesting. I’ve never seen so many things; bones, stuffed animals, rifles, etc. packed inside such a small space. It is an interesting place, so if you are ever in southern Idaho, near the town of Shoshone stop, by for a visit.

Dissolved solids in the water precipitate out on the cave walls.
Here water, the minerals in the rock and the dissolved solids; CaCO3, CaOH2, etc. react with each other.
Water enters the cave through cracks in the ceiling and oxidizes the iron in the rock (rust).
Enough indirect sunlight gets into the cave, near the entrance, that this algae can grow on the rock.
