Learn about this natural wonder!
We're excited to host this special talk, Desert Varnish: Those Rocks are Alive! Learn more about Desert Varnish, what it is and where it comes from.
Join Colorado National Monument Association (CNMA) for this special talk, which starts at 6pm, by Tim Beagley. It will focus on how desert varnish forms, what it is made of, the controversy surrounding it, and how it fits into the definition of a biofilm.
During the 5pm-7pm time you’ll have time to learn more about CNMA and the work we are doing for our beloved local national monument.
