This area will not be directly impacted by mining. Hunchhack is very deep and the sampled depth <br />extendetl to 110 inches. The mollic epipedon ranges in thickness Irom 16 Io about 25 inches. Content of rack fragments in the 10 to 40 inch control section averages 0 iD 15 percent. Clay content in the control section <br />averages 35 to 50 percent. Hunchback is poorly drained end depth to a fluctuating Iseesonall high water table is 0 to 12 inches.
