Abstract:
Hypogenic processes are well-developed throughout the lower Pecos region of southeastern New Mexico, where they are represented by strong artesian flow of groundwater from karst springs and sinkhole lakes that line the Pecos River over a distance of more than three degrees of latitude. Artesian flow from these natural features makes a substantial contribution to the stream flow in surface drainages such as the Pecos River and its tributaries. In addition, groundwater stored in karstic artesian aquifer systems in the lower Pecos region supports a robust agricultural community essential to the economy of the region. Human settlement in this part of the arid southwest would be much more limited without the benefit of hypogenic groundwater flow systems on a regional scale.
