Sideways Snow and Montana Skwalas

As Neil LaRubbio notes in the Montana Kaimen, Montana’s first big bugs of the year worry little about the weather — and create equal abandon in trout.
“A Skwala is a type of stonefly, about the size of a matchbox, that hatches from March through the end of April in rivers of the Northern Rockies. The Yakima River in Washington and the Bitterroot River south of Missoula incubate some of the most significant Skwala hatches in the region.”
