The most impressive day trip out of El Paso, was the Hueco Tanks State Park. The park is stunning and famous for rock climbing. Even more importantly, the park is known for ancient pictographs depicting the sacred relationship between man and animals. This relationship relied on the rock formed pools (Huecos) that dotted the surface of the mountainous volcanic formations. These Huecos are nurseries for tiny translucent shrimp that provide a food sources for birds and ultimately larger animals through the food chain. This desert oasis was hallowed ground for native peoples who relied on the water and animals for life in the harsh environment. Unfortunately, due to vandalism, the park is now limited to only 70 visitors per day and we felt lucky to have experienced it.
