Summary[edit] Description: Wavyleaf thistle (Cirsium undulatum), Aster family (Asteraceae). Slopes of the Uinta Canyon along the road FR117 to the Chepeta Lake, Uintah, Utah; elevation 2347 m (7700 ft). Cirsium undulatum looks the most close fit, although the leaf pattern and the branching character is different from ones I see around Salt Lake City. Date: 27 June 2015, 15:34.
