SUBSURFACE INVESTIGATION SECTION A006B, ROCKVILLE ROUTE

Results are presented of two slant borings made from the inbound running tunnel mined through the location of Zoological Park Station in Section A006b of Rockville Route of the Washington Metropolitan Area Metro System, north of Rock Creek in northwest Washington, D.C. The purpose of the work was to provide information on the probable extent and orientation of shear zones which were expected to pass through the position of the station entrance excavation on the west side of Zoological Park Station. The report contains geological sections illustrating conditions along the line of these borings, logs of the borings and a discussion of general subsurface conditions.
