Still a small cluster of Mojave mound cacti, this grey-green species of barrel cactus with their distinctive dusty pink spines normally is found in clumps of 20-40 stems. Also known as a cottontop cactus (you can see what appears to be a ball of cotton at the top of each one), in June or July in the hottest part of the desert summer, a bright yellow blossom will flower. These were found and photographed while I was searching for some shade in the Mojave desert.
