Detailed Description

By Floyd Gray, Geologist

  • Natural systems-water, geology, and wildlife-tend to cross the 1,900- mile-long arbitrary political border between Mexico and the U.S.
  • Rapid population growth on the U.S. side and in Mexican border cities is creating a variety of environmental, ecological, and human health problems
  • The San Pedro River, which flows from Mexico into Arizona, is now the most studied river in the U.S.
  • One goal of joint U.S.-Mexican studies is to combine and complete geologic mapping of the entire border at uniform scale and unit definitions
