The Dugway Proving Ground grids range in size from 1800 feet square to 150 square miles. Approximately 30 areas have been selected and instrumented for varying degrees of sampling from:

1) areas which are surveyed and staked for ballistic and functioning trials to

2) areas elaborately instrumented for chemical, biological, and meteorological sampling.  Fortification complexes are available for the determination of the degree of protection afforded against HE, chemical and biological attack and determination of the effectiveness of chemical and biological munitions in the neutralizations of these complexes.

        Test areas are also available for toxic and pathogenic hazard and decontamination studies as well as to provide service tests of the munitions, defensive items or vehicles.

        Examples of these grids are given on the following pages.
