Rock snot, formed by didymo algae, is invading North Shore streams.

Mats of golden-brown goo, called rock snot, are showing up on rocks in North Shore streams. Formed by didymo, an invasive algae, researchers think rock snot has lived in the Great Lakes for thousands of years. But the first discovery in a Minnesota stream was in 2018 in the Poplar River.
