Blue Lake Rhino
One of the most unusual fossils ever found in the Columbia Plateau is a mold and a few bones of a small rhinoceros. In 1935, a group of hikers found it in a cavity in the vicinity of Blue Lake a few miles south of Dry Falls. This fossil is commonly known as the "Blue Lake Rhino". The mold is preserved in pillow basalt overlying a thin sand bed. Probably the rhino, which was dead at the time, was lying in a small pond and as molten lava flowed into the lake and became chilled somewhat so that the lava did not burn the rhino up. A mold was formed around the dead body. Professional paleontologists have made a coast from the mold and have reconstructed the rhino. Above see a model showing how the animal may have appeared prior to burial. The actual rhinoceros measured about eight feet from snout to tail.
