Gypsum Sand Dunes
At the western end of Guadalupe Mountains National Park, down from the Mountains but with an impressive view of El Capitan, are the Gypsum Sand Dunes which will no doubt remind the explorer of the white gypsum dunes of the nearby White Sand Dunes National Park. There’s no real trail. You just park your car at Williams Road and start exploring.
You’ll be walking through ancient dried playas and near the Butterfield Stage Route. This was the first transcontinental mail route and was only able to be used after the Mescalero Apaches were finally driven from the area after 30 years of war. An intense and insightful history podcast episode is coming over the Apache so stay tuned. I also talked at length about these dunes and the Buffalo Soldiers who got stuck in them in my history podcast series over the Buffalo Soldiers.
This area was underwater 260-270 million years ago when a tropical inland sea covered the area. The Guadalupe Mountains are actually an ancient Coral Reef known as the Capitan Reef.
