Pickett CCC Memorial State Park in Tennessee’s upper Cumberland Mountains encompasses a larger protected landscape of about 19,200 acres, including roughly 1,000 acres of state park and the remainder as state forest. The area began forming as public land after a 1933 donation from the Stearns Coal and Lumber Company, and Civilian Conservation Corps crews developed key facilities there between 1934 and 1942 using locally quarried sandstone. Later expansion added more land and amenities. The park is valued for recreation, exceptionally dark skies recognized in 2015, and Hazard Cave, where rare blue-glowing fungus gnat larvae appear on cave walls and nearby vegetation.
