Presidents Obama and Calderon are trying to create an international park at the U.S./Mexico border modeled after the Waterton-Glacier Peace Park that we share with our northern neighbors. The new park would be an extension of BEAUTIFUL Big Bend National Park in Texas and would mean securing an extremely rugged area in Mexico that's the size of Rhode Island and Delaware combined. The Mexico side boasts douglas firs and ponderosa pines at 10,000 feet, crystal mountain streams, black bears and bighorn sheep. It's far from paved roads, mostly untouched and is visited by the occasional sheepherder and biologist. And drug smugglers. Lots of them.When Big Bend National Park was established in 1944 in far West Texas, President Franklin Roosevelt wrote to President Manuel Avila Camacho of Mexico, "I do not believe this undertaking in the Big Bend will be complete until the entire park area ... on both sides of the Rio Grande, forms one great international park."More info at NPR.
