The Tobyhanna Artillery Range Formerly Used Defense Site (FUDS) is 25,000 acres and is comprised of the Tobyhanna and Gouldsboro State Parks and State Game Lands #127. Visitors need to be aware that past military use of the property and the actions they should take to remain safe if they encounter or suspect they have encountered unexploded ordnance (UXO) from that training.

The Tobyhanna Artillery Range was acquired in 1912 and between then and 1949 the U.S. Army and the Pennsylvania National Guard conducted artillery training on the property. Much of the property served as an artillery range and impact area during World War I (1914 - 1918) and again at the beginning of World War II (1937 - 1941). Training at the site included firing of 37mm, 75mm, and 155mm conventional munitions. In 1952, 1,418 acres of property became the Tobyhanna Army Depot which is not part of the Tobyhanna Artillery Range FUDS. The state parks and game lands provide numerous recreational areas where the
potential to find UXO from past military activity exists.

Since the late 1990s, the U.S. Army Corps of Engineers and Pennsylvania Department of Environmental Protection have conducted activities to locate, remove, and destroy UXO.

A Decision Document was approved by USACE HQ in 2010. Past live-fire training conducted at artillery ranges located on TOAR FUDS resulted in the presence of MEC, specifically UXO, on portions of TOAR FUDS. The role of the remedial action selected for TOAR FUDS is to reduce the potential risk associated with any MEC to human health and the environment based on the current and reasonably anticipated future land use of TOAR FUDS for outdoor recreational activities in both the Park and Game Lands.
