Grand Mesa

Early in August we headed to Grand Mesa to see what we could find. Our timing was a little late, of course, and Western Colorado has been in a prolonged drought, but some recent rains seemed to help. And we found three new species for this site.

Please contact us with comments and if you see errors in identification.
