The male gopher was found dead from eating the poison in the tunnel. There was no nest or storage chambers of any kind found in this tunnel system. Either he didn't have one or else we missed them. Above was in an alfalfa field and 45 crowns were found that were cut off (and thereby killed) about five inches below the surface of the ground The depth of the tunnel varied twenty-four inches up to four inches in depth, however, eight inches is a fair average. The normal gopher tunnel system at this time is 200 feet of tunnel / 5 mounds, one nest 10 inches in diameter located to 1 1/2 or 2 feet underground, and on a more storage chamber.
