The wild world of sand dunes

The San Luis Valley’s Great Sand Dunes is one of the more unusual landscapes in the United States. In fact, so unusual that it’s protected by the National Park Service. But how unique are these dunes? Geologist Andrew Valdez will describe how Great Sand Dunes formed and then compare them to other dunes in the U.S., around the world, and throughout the solar system. Sand dunes form in response to a common set of conditions, but the local environment and material give each dune-field a unique character. They can form where you least expect them and often the result is visually stunning. So, come learn about the wild world of sand dunes and find out where other amazing sand dunes are located. The lecture will be held at 7 p.m. on Wednesday, March 29th, 2017, in Porter Hall, Room 130, on the Adams State University Campus, 208 Edgemont, Alamosa, Colorado.

Andrew Valdez is a San Luis Valley native who grew up in the greater Capulin area. He has worked at Great Sand Dunes National Park & Preserve as a geologist since 1995 and is a graduate of Adams State College. His work focuses on collecting hydrology and weather data, and monitoring dune movement. He is the chair of the Colorado Field Institute and a member of the SLV Regional Science Fair Committee.

The Colorado Field Institute is a nonprofit corporation organized in 2005 to promote greater stewardship of the natural and cultural resources within the San Luis Valley.
