Bulkley soils are on hillsides snd <br />have slopes of 3 to 65 percent slopes. The average annual precipitation <br />is about 17 inches, the average annual air temperature is about 42 <br />degrees F, and the frost-free season is about 75 to 95 days. Eleveitions <br />are 6,300 to 7,000 feet. <br />Bulkl_~ e^soils are similar to Abor, Binco, and Aaberg soils, and <br />are located near Abor, Absher, and Moverson soils. Abor soils have <br />an 40 inches. <br />average summer soil temperature. <br />content, Ptoverson sods have b~ <br />pedon of Bulkley silty clay loam <br />miles south ,st of Hayden, 2,500 <br />Aaberg and Binco <br />A~bshe~ '' h, <br />i~ k at Less than <br />12 to 25 percent <br />feet north and 1, <br />southeast corner of sec. 3, T.
