Deposition of caliche in the soils of southwestern Idaho probably results from soil‐forming processes. Caliche occurring on the lower, intermediate, and upper terraces of the Boise and Snake Rivers is described. Close correlation of the present ground surfaces with the top surfaces of the caliche layers is found. The pedogenic development of the soils is related to the ages of the terraces on which the soils occur, and also to the thickness and induration of the caliche layers. The thickness of the C ca horizon decreases or disappears entirely as the age of the soil and terrace increases. Calcium carbonate and silicates increase in the caliche horizons as the soils and terraces increase in age.
