Out in the desert of western Texas, N.E. of El Paso, are remnants of volcanic activity. Rocks warn by age but standing tall in contrast to the flat desert floor, were known by Native Americans for thousands of years, to hold water. Rain had hard pockets that created pools of water for plants and animals so these little oasis's attracted early humans.
Hueco tanks, is only one, but the best known cluster of these rock formations.
