• • Soils Information <br />The typical structure of this soil has a dark gray cobbly loam surface layer about 6 inches thick. <br />Beneath this is a lighter gray, extremely cobbly sandy loam soil containing clay seams. This second layer <br />is typically about 25 inches thick. The subsoil is an extremely cobbly clay loam about 12 inches thick. <br />Bedrock typically occurs at about 43 inches. The soil is generally acid. For further informt.tion on the soil <br />properties and characteristics see the tables and diagrams later in this exhibit. <br />Tolman Series <br />U marked contrast to the Coldcreek series, the Tolman soil series is shallow, poorly developed, and <br />far less productive. It occurs on south facing slopes. The top four inches is a dark grayish brown gravelly <br />sandy loam. This lies on top of the subsoil which is a very cobbly sandy clay loam about !a inches thick. <br />Bedrock is usually found at about 13 inches. <br />This tremendous difference in soil properties limits tree growth and encourages a sparse grass growth <br />that would be suitable for grazing except that slopes are usually too steep. The typical veg~:tation is <br />composed of mountain muhly, big and little bluestems, side-oats grama, and western wheatgrass. Mixed <br />with the grasses are mountain mahogany, skunkbush sumac, and Rocky Mountain juniper, with some <br />ponderosa pine. Occasionally piiion pine and one-seed juniper are also found. <br />Other Soils <br />As noted previously, the Kutler-Broadmoor complex can also be found on this site. Although difficult <br />to distinguish from the other soils, often these can be found by looking for Gambel Oak. P,Ithough the oak <br />can occur on the other soils, it characteristically occurs on the Kutler series. The Broadmo~>r is similaz <br />although considerably less so. <br />Soils in the bottoms of the canyons can be several feet deep where the slope gradient is fairly gradual. <br />This is probably the Nederland series, but can be a blend of several types. It is typically produced by <br />erosion from the slopes and deposition along the intermittent stream beds. <br />Ridge lines generally have thin soils exhibiting highly variable properties. Many rock outcrop areas are <br />on ridge lines, but rock outcrops can also be found on the slopes. <br />Soil Salvage <br />Soil salvage recommendations are difficult to define precisely because on this site the :>oils vary so <br />much and the slopes are often very steep, making salvage difficult. Furthermore, the abunc.ance of rocks in <br />the soil further complicates the process. Soils in the bottoms of the canyons can be salvaged where the <br />stream channel will be disrupted. <br />Soils on north facing slopes can be salvaged where it is accessible by equipment and safety does not <br />prevent its salvage. On south facing slopes a similar recommendation can be followed. Ho,vever, because <br />most soils on south facing slopes are the Tolman series there is not a great deal of sense in salvaging it. <br />The quality is very low and therefore would not provide much benefit. On the other hand, as poor as it <br />might be, it is probably better than using rock rubble as a growth medium. At least it contains some <br />Menzer Quarry Amendment Exhibit 1 Page 2 <br />
