More pics from Red Rock Canyon, which is right outside of Summerlin, in Las Vegas. When we visit LV, we always stay in Summerlin. We went a couple of weekends ago so that I could attend a mustang training clinic in Sandy Valley. I see why it is called Sandy Valley! There is a huge sand dune or dry lake there. On our way home, after we left Red Rock Canyon, we both glanced over toward Sandy Valley (it was windy that day) and saw sand swirling up into the sky! Outdoor Wednesday for May 12, 2010.
