The East Wig Grid is located fourteen miles north west of Dog Area. The grid area consists of 2900 square feet and contains thirty sampling rows spaced 100 feet apart with a sampling station located every 100 feet on each row. No power or vacuum facilities exist on the grid and sampling is accomplished through the use of remotely controlled portable sampling devices.

The facility is utilized primarily for testing of chemical munitions and dissemination devices.
