Thalictrum alpinum is primarily a species of Alaska, northwestern Canada, and the high mountains of the western U.S.  In the Four Corners area it occurs only in a few boggy areas of several counties.

Thalictrum alpinum leaves are scalloped, no more than a half inch in diameter and on stems up to several inches long.  Dried flower stems are arched in the foreground in the top two photographs.

Weber places Thalictrum in Thalictraceae, not Ranunculaceae.
