• GEOLOGIC APPRAISAL REPORT <br /> RAPID CREEK RIPRAP QUARRY <br /> CONDITIONAL USE PERMIT APPLICATION <br /> MESA COUNTY, COLORADO <br /> FEBRUARY, 1995 <br /> INTRODUCTION <br /> An application has been made to Mesa County by Mr. Rudy Fontanari <br /> of Clifton, Colorado, for approval of a conditional use permit <br /> for a quarry operation near Rapid Creek. The site is located <br /> on about 9 acres of private land owned by Mr. Fontanari and <br /> is located about 4 miles northeast of Palisade, Colorado. <br /> The purpose of the proposed quarry would be to excavate and <br /> process a deposit of soil, gravel, cobbles, and boulders for <br /> commercial uses such as riprap, road surfacing, landscaping <br /> stone, or other general construction uses. The deposit consists <br /> of a wide range of sizes from clay to large boulders and would <br /> require processing to meet each particular need. <br /> The purpose of this report is to describe and verify the site <br /> as having economic viability as a mineral resource. A field <br /> • reconnaissance of the quarry site was conducted by Mr. Rudy <br /> Fontanari, the landowner, and I on February 7, 1995. In <br /> preparing this report, reference was made to a publication by <br /> the - Colorado Geological Survey titled "Mineral Resources Survey <br /> of Mesa County - A Model Study", by S. D. Schwochow dated 1978. <br /> GENERAL GEOLOGY <br /> The subject area lies between the 10, 000 foot-high, lava capped <br /> Grand Mesa to the southeast and the Bookcliffs, an east-west <br /> trending ridge. These two features are separated- by a narrow, <br /> deep canyon, known as DeBeque Canyon, eroded into sedimentary <br /> rocks of the Mesaverde Formation by the Colorado River. <br /> SITE GEOLOGY <br /> The proposed riprap quarry site is located at the mouth of Rapid <br /> Creek on a complex and deeply dissected alluvial-fan sequence <br /> which involves several hundred acres. The present Rapid Creek <br /> is incised about 160 feet in elevation lower than the- surface <br /> of the alluvial fan at the quarry location. <br /> The quarry is within a larger area mapped by the Colorado <br /> • Geological Survey as "A-4" on Plate 2 in the report "Mineral <br /> Resources Survey of Mesa County". The symbol A-4 is described <br /> as "alluvial fan, probable sand/gravel resource. " A drawing <br /> adapted from this Survey map is attached to this report. <br /> 1 <br />
