Pockets of barren land exist in North America similar to those in Australia; however, they are generally small in area and not nearly as prominent in the landscape as deserts on other continents. Barren lands of North America are typically associated with high salinity or alkalinity, such as the Black Rock and Great Salt Lake Deserts of Nevada and Utah, respectively. Sandy deserts also exist, but are not common. For example, the Gran Desierto de Altar (Great Desert of Altar) in the northwest corner of Sonora, Mexico, is the only active erg dune region in North America.
