Sample Site Description--Road to New Refuse Pile <br /> Thirteen soil samples were taken from 11 different locations approximately <br /> 100' apart for subsequent chemical and physical analyses. The samples repre- <br /> sent composites of the total depths shown in the tables. <br /> Site 1 has been disturbed as a result of previous road construction, and <br /> the profile is quite deep since it appears that the material was pushed into <br /> the new road site. In general, the rest of the soil at the sites is represent- <br /> ed be very similar soil systems. All are a typic cryoboralf. <br /> Horizon Description <br /> Site 1: Site 1 is composed of a blocky alluvium from the road site above it. <br /> It is deep and well-drained. <br /> Site 2-11: The soils from these sites differ only with respect to depth in <br /> their characteristics. The upper 1"-2" are partially decomposed <br /> organic material, very dark grey in color (10YR 3/1) . There is an <br /> abrupt boundary to sandy loamy A2 type of horizon with a moderately <br /> blocky type of structure. It is friable and slightly acid. This <br /> horizon is generally 1"-11" to 2"-26" in depth. The variability <br /> is due to different degrees of alluvial deposit. It is medium brown <br /> in color (10YR 5/2) . The A2 grades into a B horizon which extends <br /> to as much as 40" in depth. It is also slightly acid in nature and <br /> is brown in color (10YR 6/3) . Its structure is slightly blocky <br /> and friable. Below this B horizon is a C horizon of shale fragments <br /> and sandstone gravels. The shale is presumably from the Mancos shale <br /> which underlies the entire area. It is light brown in color (10YR 5/4) . <br /> This C horizon contains varying degrees of soil from the B horizon. <br /> All of the soils as tested are slightly acid, low in soluble salts and <br />
