Skyway was also desciibatl at tour additional sites (Sites 99. 100, 103, <br />and 1041. All parameters except the rock fragment content of the C horizon, color of the A end C hprizons, antl clay content of Iha control section are within the ollicial range of characteristics. flock Iragment content, <br />consisting of channers antl flagstones, ranges from 15 to 40 percent. Some Skyway proliles have a line loamy cpntrol section with a mean clay content of 18 to 22 percent. The A horizon has a value of 3 to 5 dry and <br />chrome of 1 to 3. The C horizon value is 3 or 4 moist. Dominant vegetation et the description sites include aspen, serviceberry, snowberry, sagebrush, wildrye,and various other grasses. <br />Spicerton Variant Ifrigitl summer soil temperaturasl Mll: 5A; SN: 33 Fine, montmorillonitic, Borollic Natrargids <br />Ap 0-8 C 10YRfi/3 10YR4/3 M M SBK/ H FI S/P Com M O NE, Mild Alk CS <br /> M M GR Few F IpH = 7.71 <br />m ~ u-z» v ~..Yfl4~» ~.. ~wuro ... ... ..DK n FI S!P Faw F,M O irE, Mud Aik GS Aryiiiic iwrizon <br /> IpH = 8.01 <br />Bt2ny 24-40 C 10YR5/3 10VR3/3 S C ABK VH VFI VS/VP None O NE, Milk AIk GS Natric and Gypsic <br /> IDH = 7.61 horizon <br />Bt3ny 40-SB C lOYR5/3 10Yfl4/3 5 C ABK VM VFI VS/VP Nona O NE, Mild AIk GS Natric and Gypsic <br /> IpH = 7.81 hprizon <br />Cny 56-60 C 2.5Y6/4 tOYR4/fi/ Massive H FI VSNP None O NE, Mild Alk - Gypsic horizon <br /> 2.5 V4/2 IoH = 7.81 <br />SDiCerton Versant (frigid summer soil tempereturasl SN: 34 <br /> <br />E 0-2 C 10YR6/3 10YR4/3 5 F,M SBK H FI S/P Com F O NE.
