Page 11 <br /> 6.4.4 EXHIBIT D — Extraction Plan <br /> Vegetation Map, shown not to scale, above. Additional geologic <br /> considerations are also included under Exhibit S - Stability Analysis. <br /> Area and Site Geology: The area geology is typified by mixed alluvial and <br /> aeolian development, that is commonly alluvial in nature at lower elevations. <br /> As viewed in the Geologic Timeline and shown in Figure 1, below, the <br /> aggregate deposit is found between the Laramie and Fox Hills Sandstone <br /> formations, both formed during the Upper Cretaceous Period nearly 65 <br /> million years ago. The alluvium of the river valleys and aeolian sands that <br /> cap the hills formed of the Laramie formation north of the permit area are <br /> more geologically recent, developing during the Quaternary Period. <br /> +41ILUONS OF <br /> PERIOD V SEARS AGO <br /> NOW <br /> qua ternary <br /> 1 <br /> PlatCPnP l Ap st�, <br /> EffiFtY 0.5 <br /> Nlix-12rke Lake 1.9 <br /> Eally 3.6 <br /> I tkxene Lcae 5.3 <br /> Mdadle 11-2 <br /> EqFiy 16-4 <br /> T-ertia ry 01iWXeq*r Ld1,r � <br /> Eocene Lale 37_7 <br /> Midale__ <br /> earl <br /> Paki3ceow Lale 544 <br /> Cre-LaceoWs Eapim 165-0 <br /> 144 <br /> Jurh1L!L1t Loke <br /> Middle 159 <br /> 1BO <br /> Ear <br /> Tr»-sflc Late 227 <br /> Middle <br /> EdWy 240 <br /> Geologic Time - Livescience.com <br /> VARRA COMPANIES, INC.
