The upper three photos of Sierran peavine on this page were photographed at a DNR rock quarry at about 4100' abreast a ridge dividing the Dairy Creek and Cougar Creek drainages at the southeastern corner of Mt. Adams.........May 29, 2005. Note that the tip of the keel is as long as the wings. The similar american vetch (Vicia americana) has a keel which is much shorter than the wings.
