Goss soils are on uplands and formed in colluvium and the underyling residuum weathered from cherty limestone or cherty dolomite and some interbedded shale. Slope ranges from 1 to 70 percent. The mean annual temperature ranges from 47 to 57 degrees F, and mean annual precipitation ranges from 32 to 44 inches. These are the Gasconade , Gatewood , Peridge and Wilderness soils in the southern part of the series extent and Keswick and Lindley soils in the northern part. Gasconade soils are very shallow or shallow.
Gatewood soils are moderately deep.
The Gasconade and Gatewood soils are in similar positions where depth to rock is less than 40 inches. Peridge soils are fine-silty and are on higher positions in the landscape. Wilderness soils have a fragipan and are on higher positions in the landscape. Keswick and Lindley soils are fine and fine-loamy respectively and formed in glacial till on higher positions in the landscape. Runoff is medium to very high.
