First Word limestone: 3) Limestone, medium-gray, finely laminated, very silty with bands of brown siliceous replacement, lenses of fossiliferous calcarenite, (Collection 10' from top) --------- 84'. 4) Dolostone, "dirty" gray, 5' beds, a yellow weathering limestone 6" about 20' up - -----40'. Second Word limestone: 5) Shale, red-brown weathering ------ 10'. 6) like 4 below - ----about 30'. PG. 68 Blank PG. 69 7/27/59 Dugout Mt. Section Section 7 - dip 14°WNW.
