Jefferson Proving Ground is located in southeastern Indiana, approximately 8 miles north of the Indiana-Kentucky border and about 5 miles north of Madison, Indiana. The installation occupies parts of Jefferson, Jennings and Ripley Counties, and is about 17.2 miles in length and ranges from 4 to 6 miles in width. Lands surrounding JPG are predominantly farmland and woodlands, with some small towns and rural residential land use nearby.
The facility is divided into a Northern Firing Range Area and a
Southern Cantonment Area, separated by a firing line consisting
of 268 former gun positions used for testing ordnance until September
1994. This line runs east-west across the width of the facility
and is separated from the Cantonment Area by an east-west firing
JPG contains 379 buildings, 182 miles of roads, and 48 miles of boundary fence line.
The Southern Area houses support facilities that were used for
administration, ammunition assembly and testing, vehicle maintenance,
and residential housing. Up to September 1994, this area also was
used for ammunition assembly and testing and weapons maintenance.
Most of these buildings are situated along a 1-mile strip just south
of the Firing Line Road on Woodfill Road. An abandoned airport with
four runways and a hanger building are located in the southwest
corner of the facility.
The Northern Area consists of 51,000 acres of undeveloped and heavily wooded land. Numerous discrete areas were cleared and targeted during certain munitions tests.
