06LenoreCave
The Lake Lenore Caves were a bit of a disappointment for their lack of depth and/or cool stuff like bones or petroglyphs. Supposedly they were formed by sideways vortices in the Missoula floods, kind of like a tornado in the water. A number of us were skeptical of this idea, one reason being that the large talus piles now sitting below the caves would have been washed away if indeed the caves had been carved during the flood. (It looked like the volume of rock in the talus pile was roughly comparable to the size of the cave). Note the colorful lichens on the rocks on the left.
