Immediately west of the towering escarpment of the Guadalupe Mountains lies an other-worldly landscape. The Salt Basin Dunes rise modestly above the surrounding salt flats, the remnants of an ancient sea. These dunes of snow-white gypsum are formed by the collaborative artistry of the winds and the white sands of the salt flats.
The process is not entirely complicated. When the winds whip across the salt flats they pick up tiny crystals of gypsum. When these airborne grains slam against the western wall of the Guadalupe Mountains they are deflected upward and then fall back to earth to form the undulating landscape of the Salt Basin Dunes.
From the top of Guadalupe Peak, the highest point in Texas, the salt flats seem strangely out-of-place in the otherwise desert-looking landscape. They have the appearance of snow blanketing the floor of the Chihuahuan Desert. The sight of the salt flats from Guadalupe Peak is quite spectacular and beckons exploring.
The Salt Basin Dunes are a part of Guadalupe Mountains National Park and are accessible by ranch roads not far from Dell City. This day use area offers access to the salt dunes by way of a two-plus mile hike. Because this is a delicate ecosystem, visitors should stay on the trail and not break the fragile cryptobiotic crust beyond the trail. This thin crusty topsoil is essential for preventing erosion, producing soil nitrogen, and stabilizing the soil for vegetation to take hold. So, don’t bust the crust!
The dunes themselves are pretty spectacular. Although this seems to be the most inhospitable of environments, animal tracks in the sand indicate the presence of nocturnal animal activity. Various desert plants also accentuate the stark white dunes. Yucca, cholla, cactus, and various grasses have staked their claim to life on these shifting dunes.
While the view of the dunes is beautiful from atop Guadalupe Peak, the view of Guadalupe Peak is awe-inspiring from the dunes. You can, in fact, see five of the seven named peaks in Texas that rise over 8,000 feet. From north to south you can see Bush Mountain, Bartlett Peak, Shumard Mountain, Guadalupe Peak, and El Capitan keeping vigil over the dunes.
Regardless of when you visit the Salt Basin Dunes be sure to carry more water than you think you’ll need, a snack or two, and sunscreen in your day-hike bag. Stay on the trail. Have fun exploring the dunes. Take lots of pics. Take a moment to stop and enjoy the silence of the desert. Look toward the east and breathe in the beauty of the Guadalupe Mountains. And, leave no trace but your footprints in the sand.
