<br />Bakeoven
<br />Found on mountains, ridgetops, hillslopes, mesas, and benches. The parent material consists of mixed slope
<br />alluvium, loess, and residuum weathered from basalt. Depth to a root restrictive layer, lithic bedrock, is 10
<br />inches. The natural drainage class is well drained.
<br />Benwy
<br />Found on structural benches, highly dissected fan terraces, hillslopes, backslopes, summits, and footslopes and
<br />toeslopes of plateaus. The parent materials consist of loess, colluviums, and alluvium from loess and basalt.
<br />Depth to a root restrictive layer, duripan, is 40 to >60 inches. The natural drainage class is well drained.
<br />Blint
<br />Found on upland hillslopes. The parent materials consist of loess mixed with volcanic ash in the surface over
<br />basalt colluvium. Depth to a root restrictive layer, bedrock, lithic, is 20 to 40 inches. The natural drainage class
<br />is well drained.
