Interval (ft.) Description 



2110 — 25 Coarse, gray, unconsolidated sand. 



2125 — 35 Red, slightly mottled claystone. 



Top Cramer formation (Oligocene) 



2135 — 90 Medium-grained friable sandstone with 10 percent red claystone. 



2190 — 2210 (Core 1) (15 feet recovered). Dark-gray shale with thin streaks of 

 fine-grained, slightly oil-stained sandstone (medium acetone cut, strong 

 fluorescence) ; shows few high-angled fracture planes with faint striations 

 at 60° to the axis of core; average dip about 16°; locally 12° and 22°; 

 hole deviation 2° off vertical.
