-b- <br />1 foot + - 3 percent <br />6 to 12 inches - 12 percent <br />2 to 6 inches - 25 percent <br />to 2 inches - 25 percent <br />Sand - 20 percent <br />Silt and below - 15 percent <br />The fragments above 4 inch in diameter are generally subrounded and competent <br />with little obvious weathering. Some fragments of igneous or metamorphic <br />rocks show some weathering or fracturing but consist of less than lY, of the <br />total volume. The majority of the coarse fraction 85% + consists of the <br />Crestone Conglomerate which appears to be extremely well indurated. <br />The abandoned pit to the northwest of the application tract has been re-shaped <br />so a good profile was not visible. It appears to be quite similar to the <br />active pit but contains approximately 10% of a quartzitic material which was <br />not apparent in the active pit. This pit is approximately 20 to 25 feet deep <br />showing the coarse grained gravels extending to approximately 15 feet from the <br />surface. The lower portion of the pit consists of a fine to medium grained <br />sand with approximately 15% + 4 inch material. A similar material exists in <br />the southwest portion of the application tract indicating that portion may not <br />be suitable for the intended purpose. <br />It is obvious from exposures on the subject tract and evidence from <br />immediately adjoining tracts that suitable material exists on most of the <br />tract. It is estimated that material exists in place to an average thickness <br />of 15 feet over the entire area. The tract south of the county road contains <br />approximately 25 acres of suitable material. I estimate approximately 600,000 <br />cubic yards of material exists on this portion of the tract. Assuming 85% of <br />the material is usable, the resources are estimated at 510,000 cubic yards. <br />The tract north of the county road consists of approximately 15 acres of <br />mineable reserves. This is approximately 360,000 cubic yards at an 85% <br />recovery rate. The total recoverable reserves of the subject tract are <br />approximately 818,000 cubic yards. <br />
