Description Date | Jul 21 2014 |
Describer | D. Kohake, J. Hellerich, A. Baldwin, C. Remley, J. Anderson |
Site ID | S2014KS045001 |
Site Note | Sampled the shale residual component of a 7550 Rosendale-Bendena map unit. |
Pedon ID | S2014KS045001 |
Pedon Note | This profile is a taxadjunct to the Rosendale series. It is similar to Rosendale being a residual soil in the lower half of the profile, but it has a thicker dark mollic surface and an argillic horizon that Rosendale doesn't have. |
