Andrew Valdez is a Physical Scientist and is the first, and only, geologist at Great Sand Dunes National Park and Preserve. He is a native of Alamosa, Colorado - which is the gateway city to the Great Sand Dunes. Valdez was hired full-time with the NPS in 1994 and his work as a geologist helped lead the Great Sand Dunes to national park status.
In this conversation, Andrew and I chatted all about the geology and hydrology of this magnificent landscape.
It was such an honor to have Andrew join the podcast. He is filled with incredible passion and knowledge for the Great Sand Dunes.
