Soil Map

This is a soil map of the area surrounding the soil pit. The pit is marked by the red circle. According to the USDA web soil survey the soil pit is located in Willamette Silt Loam, this is a Silty glaciolacustrine deposit (sediments which have been deposited into lakes by glaciers) which was transported here by the Missoula Floods. The Area along Frasier Creek is a Bashaw Clay which is a clayey alluvium that is derived from Basalt. This soil was deposited over time by the river flowing in that area. It is interesting how different these two soils are and their different histories despite being right next to each other. Also as you travel up the hill into the fields of the farm the soil becomes a Woodburn Silt Loam. Some of the other interesting things we noticed in the soil pit was the presence of a plow layer despite now being in an uncultivated spot, and a large krotovina which is a filled in animal burrow. The soil tells the history!
