The advocacy organization includes several of the "crown jewels" of the U.S. park system on its annual list of "America's 10 Most Endangered Parks." This year's list, released Monday, includes Big Bend National Park in Texas, which is threatened by water diversion from the Rio Grande and trans-border air pollution from Mexico, NPCA says. The NPCA report says domestic power plants have lowered air quality in the Great Smoky Mountains National Park on the North Carolina-Tennessee border. And Everglades National Park -- hemmed in by growth on Florida's coastlines -- faces an oil-drilling proposal at its northern border in the Big Cypress National Preserve. History on the line The NPCA's information indicates that Federal Hall -- the historic site of the first Continental Congress, a few blocks from the World Trade Center site in Manhattan -- is underfunded. Another Revolutionary War site, Pennsylvania's Valley Forge National Historical Park, is surrounded by suburban growth and also faces funding problems, the group's data shows. Encroaching development and poor funding also threaten Montana's Glacier National Park and the Mojave National Preserve in the southern California desert, according to the group. The NPCA cites three different types of vehicle traffic which pose risks to federal parks: Proposed highway construction in Georgia's Ocmulgee National Monument, which endangers wildlife. Increased cruise ship traffic in Alaska's Glacier Bay National Monument. And winter snowmobile traffic in Yellowstone National Park, the first and oldest national park in the world.
