Don Barrett (aka DBs travels)'s photos with the keyword: Great Sand Dunes National Park

People on the dunes… I find the smoothness and shadows of dunes entrancing, but have lost just about all interest in struggling through deep sand – particularly when getting to the dunes means dealing with very dense swarms of very aggressive mosquitoes.

There's actuall several humans in this picture, along the crest of the dunes.

Great Sand Dunes National Park, about 19,000 acres of sand dunes and reaching a height of 750 feet. AND, when I was there, zillions of mosquitoes.

The Conservancy manages the ranch: “to protect their significant natural values and to demonstrate how cattle and bison operations can co-exist with conservation efforts.” Source: www.nature.org/ourinitiatives/regions/northamerica/unitedstates/colorado/placesweprotect/zapata-ranch.xml
