Jeff Diener (EPOBio’92) photographed this hiker exploring “The Wave,” a stunning rock formation on the border of Utah and Arizona. Large sand dunes covered this area 190 million years ago. Over time, the dunes were compacted into sandstone hills and erosion exposed the fins and ribbons of spectacular layering visible today. As a natural world and adventure photographer, Jeff explores and captures beautiful areas across the western U.S. More of his work, along with fine art prints, are available at www.jacksonholegallery.com.
