'Field Notes': The Tale Of Montana's Strangest Frog

Ascaphus montanus tadpole.
(PD)

Several decades back while working as a biologist in Oregon, I was picking rocks off the bottom of a rushing stream. While investigating the underlying aquatic insects, I encountered an odd animal. It was what appeared to be a tadpole stuck to the bottom of the rock! Assuming all frogs and tadpoles occur in swamps, not in high elevation rushing streams, I wondered what it was doing there.
