    Parks For The People

    Public works projects are necessary to support public parks. Restrooms, amphitheaters, and visitor center facilities are some examples of amenities one can expect to find at a national park in the 21st Century. This episode examines the role workers from the Civilian Conservation Corps, Mission 66, and Parkscape USA had in creating this specialized infrastructure. Carlsbad Caverns National Park is known for a unique natural landscape, but its human history is as as abundant as the cave’s speleothems.
