No samples of <br />the processed material were available for evaluation at they time of this <br />investigation. <br />SITE CONDITIO~JS <br />A topographic map of the general area is shown on Fig. 1. The site is <br />located south of Craig, Colorado, adjacent to State Highway No. 13. The <br />highway is located in a cut immediately north of the proposed disposal site. <br />The area of the disposal site is located on a long, gently sloping ridge top. <br />Scuth and west of the site the ground surface becomes quite steep and drops <br />sharply into a stream bottom area. The site is to the west of entry for <br />Mine No. 9, and north of an area p resently used for sedimentation ponds. Ap- <br />parently the area of proposed refuse disposal site was mined far sand and <br />gravel by the County or the State during the construction of roads in this <br />area. The site is essentially irregular along the surface.The surface has <br />:the appearance of an abandoned borrow pit. Apparently, a relatively clean <br />deposit of either sand and gravel, or a slightly cemented conglomerate occurred <br />at the this site in the past. The granular materials have been removed, for <br />the most part. The surface is irregular in some areas and it appears that <br />the method of removal included ripping with some type of heavy equiprent <br />and then loading probably with a large bucket loader. Some piles of gravel <br />and sand still occur on-site and there are evidences that somztime either <br />r <br />
