Megapit Pedon Description

Print Date Jul 22 2015
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.
