<br />ass,! <br /> <br />. <br /> <br />. <br /> <br />embedded in a matrix of gypsum and mudstone. <br /> <br />Regardless of its origin this deep breccia does not appear <br /> <br />alarming to the writer after examining the cores and in <br /> <br />view of the ultimate water levels and the results of ad- <br /> <br />jacent drilling. <br />4. The stream water turned into the "glory hole" sink carne <br /> <br />out on the surface a short distance away. This fact and <br /> <br />visual study of other sink holes, quarries and the tunnel <br /> <br />present good evidence that the solution features of evaporite <br /> <br />are shallow and short in length. <br /> <br />5. The evaporite cannot maintain openings at depth due to its <br /> <br />plastic flowage characteristics under high superincumbent <br /> <br />rock loads. <br /> <br />6. Final water level measurements made in the reservoir area <br /> <br />exploratory holes showed static levels at, or above, present <br /> <br />stream elevation. <br /> <br />In addition to the above investigation and at the request of <br /> <br />the Board of Consultants, a study was made to determine the most likely <br /> <br />path that leakage would take, provided the evaporite did contain voids <br /> <br />through which the reservoir water could pass. This study pointed out <br /> <br />three possible paths; one, southwestward from the reservoir to an out- <br /> <br />crop of evaporite along Red Canyon Creek, approximately 6~ miles dis- <br /> <br />tant and approximately 360 feet lower in elevation; a second northward <br /> <br />to Gypsum Creek and Brush Creek, a distance of 12 miles and to elevations <br /> <br />- l2 - <br />
