Page 110 <br /> 6.4.5 EXHIBIT D — Extraction Plan <br /> Soils found within the entire project area are described more thoroughly <br /> under Exhibit I - Soils Exhibit, and the attending Exhibit I/J - Soils and <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 /> MPILLIONS OF <br /> ERA PERIOD MIN tkKI4 YEARS AGO <br /> FJ Ow <br /> Quaternary -- <br /> �I�r,str�t t ate 1D.1 <br /> EffiFtY <br /> 1.9 <br /> Liucene Late11-2 <br /> NEI Middle 145 4 <br /> Eady <br /> 23.7 <br /> T # x 01iWAM* Laae <br /> Eocene Late 3 3 .7 <br /> Middle 49-0 <br /> Pak- cene Lale 5aJA <br /> CRe�reous 4a 65.0 <br /> Ei #q n <br /> 144 <br /> ��Middle 159 <br /> 1B0 <br /> Early 206 <br /> TrId3fm Lite <br /> M{dd�e �� <br /> IEi -0� <br /> 2419 Ji <br /> Geologic Time- Livescience.com <br /> VARRA COMPANIES, INC.
