Morset soils are on alluvial fans, high terraces, plateaus, and outwash plains. Slopes range from about 2 to 25 percent. These soils formed in thick calcareous medium to moderately fine textured transported materials derived from sedimentary, igneous, and metamorphic rocks. The mean annual precipitation is about 14 to 18 inches with peak periods of precipitation in the spring and summer. These are the Forelle and Leavitt soils.
Forelle soils have an ochric epipedon and lack a calcic horizon.
Leavitt soils lack a calcic horizon. These soils are used for grazing or for irrigated hay meadow. Native vegetation is sagebrush, needlegrass, bluebunch wheatgrass, and junegrass. The series is of moderate extent. Jackson County, Colorado, 1973.
