This is the topsoil locus for WSC3. Dark brown silty topsoil, with not very many materials so far. Bottom elevation below south datum, in the approximate center of the trench. Top elevs are as follows, clockwise from N corner, 2142.141, 2143.498, 2143.242, 2142.460 in the W. The top elev listed above is an average because I was absent the day the topsoil was removed and am not sure what the elev was in the approx center of the trench.
