This is not the best angle to photograph this rock, but I liked the Moon rising above the Granite Range near Gerlach, Nevada. This glob of basalt squeezed up through a small fissure on the southern end of the Modoc Plateau ~25million/yrs ago. Then during the Pleistocene, Lake Lahontan filled the Smoke Creek Desert & underwater springs coated this rock with calcite (CaCO3) forming tufa. Today, the tufa has partially sloughed off.

A black and white landscape photo of a large geologic feature. Filling the left side of the frame is a large block of lava rock. The lava rock is very dark but there is a lighter colored rock in places around the top that is like a thin crust. A tiny Moon is seen over a distant mountain range on the right.
