Fort Ritchie at Cascade, Maryland was a military installation southwest of Blue Ridge Summit, Pennsylvania and southeast of Waynesboro, Pennsylvania in the area of South Mountain. Following the 1995 Base Realignment and Closure Commission, it closed in 1998: "Out the Gate, by '98".
In 1815, the Buena Vista Ice Company constructed two lakes at the site. It was controlled by the Maryland National Guard from 1926–1942; the US Army activated the Military Intelligence Training Center (MITC) on June 19, 1942  and trained 19,600 intelligence troops, including the Ritchie Boys. Support for Raven Rock Mountain Complex transferred to Fort Detrick on October 1, 1997.
Historic Preservation at Fort Ritchie
The Corporate Office Properties Trust intended to redevelopment---preserving historic buildings, finding new uses for them, and maintaining the natural beauty of the land and its lakes. Unfortunately, COPT walked away from the deal two years ago and now no redevelopment is going on at the fort. 
Fort Ritchie is a new mixed-use development. Corporate Office Properties Trust (COPT), developer of the project, is creating a "live-work-play" community designed to be an environment that inspires success. The plan intends the new community of Fort Ritchie to become a regional economic engine by attracting Fortune 500 companies, government tenants, small businesses, and residents.
