The visitors center at California's Lava Beds National Memorial is two 1974 trailers bolted together. If the center was on private land it would have been condemned five years ago. The safety of visitors and park staff is threatened. The Monocacy Aqueduct in the Chesapeake and Ohio Canal National Historical Park in Maryland is a true icon of early American engineering. It is the largest and most impressive of the eleven aqueducts erected along the canal.
Historians say it is one of our nation's finest canals.
Today the aqueduct sits atop a list of the 11 most endangered historic places. The aging structure may soon become more damaged by frequent floods, and jeopardize the safety of our visitors and the restoration of this magnificent structure. Yosemite National Park, with its high cliffs and waterfalls and marvelous giant sequoias, is also home to an antiquated sewage system - with parts dating back to the 1930s. The system's crumbling clay pipes are causing sewer spills in Yosemite Valley. The failure to prioritize maintenance of our national parks has left them near the breaking point.
