I have to write the soil section for Glen Canyon. I am not a geologist. I am not a soil biologist. But I can read and interpret maps. Google earth helps too. Some new vocab: Lithic: of or relating to stone Colluvium: soil blown and deposited at the bases of cliffs Allivial: soil transported by fast moving water, and deposited where the water slows down Eolian: transported by wind Intefluves: high area between two drainages Torriorthents: a kind of shallow, sandy soil derived from sandstone. Pagina ( I know, and one of the common bacteria associated with soil crusts is called vaginitus): the state soil of utah. Another shallow, well drained, low organic matter soil. So that's my formation of new neural connections for the day.
