4 . <br />as prominent interstream divides, shows that the p=_diments uere <br />formed prior to the development of rscant drainage patterns, and <br />the gravels are therefore regarded a=_ P1=_istocene in ao=_" (Hail, <br />idem., P. 87). These gravels do not crop out on the 6cur^, property. <br /> <br />Alluvium <br />A veneer of alluvium covers Hann Draw and its tributary gu_ches <br />on the 6ourg property. This material is G to about 2G Feet thick <br />and is quite fine-grained, consisting of loam, silt, =_nd sand, in <br />that order. Its fineness is mainly due to the cutcro~ of Pi=_rre <br />Shale in almost all of the Plann Craw drainage. <br />Landslid=_s <br />A landslide, about 7G feet vide and i3C feet long is present <br />~~ near the northern boundary of the Douro property (Plate C). This <br />is evidently sliding of surficial malarial due to local overst=_aping <br />_ of the slope caused by weathering and erosion of the Sudduth Seam, <br />~ immediately downslope from the original site of this materi=_i. <br />Stratigraphic Section <br />The following stratioraphic section extends from the upper <br />part of the '-ierre Shale to 52 3/4 feet above the Sudduth co=_1 soon. <br />As the Bourg pit op=_ns up, three det_il.=_c stra~ieraphic ..=cticns <br />will be made of the entir= overburden section on the ccuro cro=- <br />erty.
