I hiked part of the of the Sweetwater Trail on March 26, and it was beautiful with a wide variety of wildflowers. I observed Monoptilon bellioides (Mojave Desertstar), Penstemon subulatus (Hackberry Beardtongue), Calochortus kennedyi (Desert Mariposa Lily), and Mirabilis bigelovii (Wishbone-bush) here.

Behind the rock outcropping in the above photograph, the sprawling city of Tucson can be seen in the distance.
