<br />MAN -MADE FILLS FOR CONSTRUCTION OF ROADS AND BENCHES. FILLS CONTAIN MIX OF LOCAL
<br />COLLUVIAL SOILS AND EXCAVATED BEDROCK. THIN VENEER OF FILL MAY
<br />LOCALLY COVER BEDROCK OR COLLUVIAL SOIL.
<br />COLLUVIAL SOILS UNDERLAIN BY MESA VERDE FORMATION OR MANCOS SHALE. CLAYEY
<br />SOILS CONTAINING SIGNIFICANT PERCENTAGE OF PARTLY SUBANGULAR COBBLES
<br />AND BOULDERS OF BASALTIC ROCK.

<br />OF MESA VERDE FORMATION.
<br />BOREHOLE DRILLED AS PART OF ROCK SLOPE ENTRY PORTALS INVESTIGATION (1986 AND 1987).
<br />BO EHOL S AND (19BI)ST PITS COMPLETED DURING PHASE II GEOTECHNICAL
<br />ESTIMATED FILL THICKNESS AT SELECTED LOCATIONS.
<br />NOTES. 1) GEOTECHNICAL CONDITIONS DOCUMENTED BY FIELD MAPPING FOR RECLAMATION
<br />PLAN, JANUARY, 1983.
<br />2) FILL THICKNESS CONTOURS ESTIMATED BY COMPARISON OF ORIGINAL AND
<br />CURRENT TOPOGRAPHY.
<br />3) SIGNIFICANT QUANTITIES OF BASALT COBBLES AND BOULDERS MAY BE PRESENT
<br />THROUGHOUT COLLUVIAL SOILS.
<br />4) BEDROCK CONTACTS ESTIMATED IN ROTARY BORINGS (RS -5 AND RS -6) MAY
<br />NOT BE ACCURATE.
<br />5) NO GROUND WATER ENCOUNTERED IN ANY BOREHOLES WITHIN COLLUVIAL SOILS.
