Do we Flats Quarry Soils and Geology Report <br /> fine limestone pebbles and sand-sized fragments which results in equivalent readings of the <br /> whole soil (3/4 inch and smaller) of 40 to 50 percent. <br /> COMPETING SERIES: There are currently no competing series in this family. <br /> GEOGRAPHIC SETTING: <br /> The Laporte soils are on upland hills and ridges. <br /> Slope gradients range from 2 to 60 percent. <br /> The soils formed in material that weathered from or is strongly influenced by the underlying <br /> limestone bedrock. <br /> At the type location the average annual precipitation is 15 to 18 inches, most of which falls <br /> during the spring and early summer. The frost-free season is about 135 to 150 days. In central <br /> New Mexico, the mean annual precipitation is 12 to 15 inches and the mean annual temperature <br /> is 48 to 52 degrees F. The frost free period is 110 to 135 days. Elevations are 6,800 to 7,500 feet. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Pinon, Penrose, and Kin) soils. <br /> These soils lack mollic epipedons. <br /> DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; moderate <br /> permeability above the bedrock. <br /> USE AND VEGETATION: These soils are used mostly as rangeland, however, they are tilled <br /> locally. Principal native vegetation is blue grama, western wheatgrass, needle-and-thread grass, <br /> Russian-thistle, yucca, and cactus. <br /> DISTRIBUTION AND EXTENT: Colorado, Montana, New Mexico, and Wyoming. The series <br /> is of large extent. <br /> MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana <br /> SERIES ESTABLISHED: The Fort Collins Area, Colorado, 1927. <br /> REMARKS: This revision changes the classification from mixed to carbonatic minerology. <br /> National Cooperative Soil Survey <br /> U.S.A. <br /> 14 May 2, 2022 <br />
