It may be hard to believe, but these sand dunes, the largest in North America…
… were formed by millions and millions of years of erosion of the San Juan mountains, more than 65 miles west of here. The rocks are broken down by countless centuries of erosion water, freezing, and wind. They are then light enough to be blown by the wind until they pile up against the Sangre de Cristo Mountains. Try to imagine the length of time it might take for that to happen on this scale.
In my younger days, when I lived in Denver, I climbed the peaks and ridges of the Sangre de Cristo range hunting for big mule deer bucks. While I had some exciting adventures in my attempt, I never did get one. While I no longer have any interest in killing one, I did get a few earlier this evening with my camera.
