Pit and Trenches at 52nd Court

POIs 13 and 14 were the northern circular trenches and a side pit. On January 5, 1993, laboratory glassware and munitions were found buried 

The 1918 and 1927 aerial photographs show the trenches and the pit. Several documents in December 1918 give directions for disposal operations and the filling in of the trenches before the ground freezes. It appears that the burial in the pit occurred as a result of these directives.
