LEGEND: <br />• <br />• <br />TOPSOIL AND ORGANICS. <br />a CLAY: Slightly sandy to very sandy, low to highly plastic, very stiff to medium stiff, <br />~ slightly moist to wet and brown to gray in color with. calcareous deposits.. <br />.SANDS AND CLAYS: Fine grained, low to moderately plastic, stiff to dense, slightly <br />''--_ moist to very moist and brown in color. <br />^ CLAYSTONE-SHALE BEDROCK: Slightly sandy, fine grained, moderately to highly <br />plastic, hard to very hard, slightly moist to moist and gray in color. <br />Large Disturbed Sample. <br />Small .Disturbed Sample. <br />Drive Sample, California Liner Sampler. <br />~ Indicates depth at which perforated PVC was set for future groundwater level measurements. <br />18/12 Drive Sample Blow Count, indicates that 1$ blows of a •140-1b. hammer falling 30 <br />inches were required to drive the sampler 12 inches. <br />0_i Indicates depth to groundwater at the time of drilling/excavation, and 1 day after. <br />NOTES: <br />1) The test holes were drilled on May 29 and 30, 2007 with an all terrain drill rig using 4-inch diameter <br />augers and the test pits were excavated with a Bobeat 337 trackhoe on May 30, 2007. <br />2) Locations of the test holes and test pits were determined in the field by a representative of N1PCC and <br />Twentymile Coal by pacing from existing stakes and topographic features at the site. <br />3) Elevations of the test holes & pits were not determined and the logs are drawn to the depths investigated. <br />4) The lines between materials shown on the loge represent the approximate boundaries between material types <br />and transitions may be gradual. <br />5) The water level readings shown on the logs were made at the time of excavatioa/drilling. <br />Fluctuations in the water levels will probably occur with time. <br />GEND AND N(JTES <br />Job Name: 6MN Pond 2 <br />zo°at~°n: Foidel Creek Mine, Routt County, Colorado <br />Date: <br />7/18/07 <br />~~, <br />~ 07 " ~~ (6TOf8T¢7988•Fnc(970}47¢1891 <br />Fl ure ~~7'JBT~2e Div, FA.BxT757I6 <br />g # 5 57eamJOM Sam, CaNratlG 80077 <br />
