CU-Boulder environmental studies doctoral candidate Ethan Welty captured this formation of sand ripples amid sparse grassy vegetation in the Erg Zehar dune field, a two-day trek via camel from the road’s end at M’ Hamid, Morocco. Welty and his mother journeyed across the Atlas Mountains in 2007, hired a guide and continued south into the beginnings of the Sahara Desert.
