I'm not even sure they are amphibian.
This slow moving stream appeared to be without fish, but there were wandering gartersnakes nearby, they eat something.
I heard a few plops that sounded Rana in nature, and Columbia Spotted Frogs were visually seen in other streams and ponds.

Are these amphibian eggs? If so, which might they be?
