Preliminary Report for Data Recovery at Sites MK -1-082317 and MK -2-082317 Colowyo Coal Company <br />Figure 21. Site MK -2-082317, Feature 5, Full Excavation, facing west. <br />3.2.3.5 Feature 6 <br />Feature 6 is semi -circular dark stained sediment with sparse charcoal flecking and HAIR <br />measuring approximately 44 cm north to south by 45 cm east to west (Figures 22 and 23). Actual <br />top of the feature is unknown. However, the feature appears to be approximately 15 cm below <br />ground surface. The size and location of the feature within the site grid system necessitated one <br />1 by 1 m unit being established to investigate it. <br />The feature's depth below the mechanically exposed surface is 15 cm below the 152N 186E unit <br />datum. Overall feature shape appears to be roughly circular in planview with a deep basin profile. <br />A prior ground disturbance cuts into the northern part of the feature. Burrowing insects have <br />caused minor distortion of the feature boundaries. Feature fill consisted of dark stained sediment <br />(10YR3/1, Very Dark Gray) with moderate dense charcoal flecking. Several unaltered rocks are <br />also included in the feature fill. Of the HAR, one piece is 10 cm diameter size class (1.0 kg); four <br />pieces in the 10 to 5 cm diameter size class (0.20 kg); and four pieces in the 5 to 3 cm (0.8 kg). <br />The sandstone HAIR is angular, reddened, fractured pieces. <br />Tetra Tech September 29, 2017 <br />
