![]() ![]() Esquatzel and Warden soils are coarse-silty. Cencove soils are coarse-loamy in the upper part and are on alluvial fans and terraces. Burbank soils are sandy-skeletal and are on terraces and terrace escarpments. GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing The frost-free season is 130 to 200 days in Washington and north-central Oregon, and 100 to 150 days elsewhere. The mean annual air temperature is 47 to 53 degrees F. The mean annual precipitation is 6 to 12 inches. The climate is arid or semiarid and summers are dry. Elevations are 150 to 2,800 feet in Washington and north-central Oregon, and 2,500 to 4,500 feet elsewhere. These soils formed in sands from mixed sources, but contains significant amounts of dark colored basaltic sand. Many of the low rounded ridges are narrow and long. GEOGRAPHIC SETTING: Quincy soils are on uplands, fan piedmonts and terraces, some having a ridged, hummocky, or dune microrelief. Zorravista soils calcareous throughout contain lacustrine lake sediments below 44 inches in some pedons Winchester soils have more than 75 percent of the sand fraction in the very coarse, coarse, and medium size classes Walco soils 20 to 40 inches to a lithic contact (basalt) Toll soils particle-size control section dominated by sand of mixed alluvial origin noncalcareous throughout Rinquin soils 20 to 40 inches to a paralithic contact (siltstone) Quinton soils 20 to 40 inches to a lithic contact (basalt) Painter soils 20 to 30 inches to a paralithic contact (granodiorite) 24 to 40 inches to a lithic contact (granodiorite) Lachim soils 20 to 40 inches to a paralithic contact (granite) Incy soils particle-size control section dominated by sand of granitic origin noncalcareous throughout Hotsprings soils particle-size control section with 20 to 35 percent fine gravel Goldrun soils particle-size control section dominated by sand of mixed origin with moist value greater than 4 0 to 15 percent durinodes Some pedons have unconforming materials, including coarse sand, fine sandy loam, very fine sandy loam, silt loam, very gravelly sand, very gravelly loamy fine sand, at depths below 40 inches. Reaction in the upper 20 inches is slightly acid to moderately alkaline, and below 20 inches it is neutral to moderately alkaline. ![]() The matrix below 15 inches is noncalcareous in some pedons. The upper 15 inches of these soils is free of lime, except for small particles brought up by insects and animals. If the clay content exceeds 5 percent, more than 75 percent of the sand fraction can be in the very coarse, coarse and medium size classes. Less than 75 percent of the sand is very coarse, coarse, and medium if the clay content is less than 5 percent. The 10 to 40 inch particle-size control section ranges from sand to loamy fine sand. Organic matter in the surface horizon when mixed is less than 1 percent. ![]() Value is 4 to 7 dry, 3 to 5 moist and chroma is 1 to 4 moist or dry. These soils are dry in all parts between depths of 7 and 20 inches. These soils are moist in the winter and spring but are dry more than one half of the time the soil temperature exceeds 40 degrees F., about 105 to 130 consecutive days. RANGE IN CHARACTERISTICS: The mean annual soil temperature is 50 to 57 degrees F, and the mean summer temperature is 66 to 78 degrees F.

TYPICAL PEDON: Quincy fine sand-grassland. TAXONOMIC CLASS: Mixed, mesic Xeric Torripsamments The mean annual precipitation is about 10 inches and the mean annual temperature is about 52 degrees F. The Quincy series consists of very deep, excessively drained soils formed in sands on dunes and terraces. Official Series Description - QUINCY Series LOCATION QUINCY WA+CA+ID+OR
