1 <br /> ' June 19, 1987 <br /> The report prepared by AAI, was titled "Stability Assessment Final Cut <br /> ' Outline, Mr. And Mrs. J. Schmahl, Parcel A, Unaweep Canyon". An nalysis of <br /> the stability of highwall was made for the interim and proposed final c figuration <br /> ' conditions. We did not identify highwall stability concerns on revi w of this <br /> ' document. <br /> 1 <br /> tSITE CONDITIONS <br /> ' A Geotechnical Engineering Group, Inc, representative visited the <br /> ' Unaweep Quarry site on November 8 and December 13, 2000. We obc erved the <br /> highwall area and embankment area. Observation of the highwall indicated <br /> ' areas of active talus and fractured rock. The top of the highwall was ot served to <br /> ' be near vertical and about 110 feet in height (measured using tape easure). <br /> ' Several benches (10 to 25 feet horizontal) were noted below the face ith near <br /> vertical drops and 1 or talus piles in between. A 3 foot tall berm wa located <br /> ' approximately 150 down slope of the highwall. The highwall area was c mposed <br /> ' of igneous rock. The majority of the wall was massive granite with rr icaceous <br /> intrusions. The rock face was generally rubblized. <br /> 1 <br /> Rhino Engineering,Inc. <br /> ' Unaweep Quarry <br /> GEG Job No.593 4 <br />
