Lab sample # MU053697. 10YR branching mottles are preferential flow paths between prisms. The 7.5YR 4/6 mottles are oxidized zones around the perimeter of the vertical streaks. Water was perching on top of this horizon when it was described, seeping laterally into the pit quite freely. Ken Vogt was in eminent danger of permanent entrapment (like a mastadon in a tar pit) before completion of the description. Brittleness is in the brown portion of the matrix.; discontinuous - phpvsfiid 145198; discontinuous - phpvsfiid 145198
