Suggested correlation in Simpson seeps region

November 1, 1949

During the 1949 drilling season eight core tests were completed in the Simpson Seeps area up to October 25th„ This program, which is still in progress, was undertaken to provide an explanation for the surface seeps near Caps Simpson. The shallowest of the eight holes reached 800 feet; the deepest was drilled to a depth of 1460 feet.

Geophysical data on the shallow horizons indicate that the Simpson Seeps Core Tests shown on the section have been drilled in an area of nearly north-south strike. The five core tests that most nearly approximate a section normal to the strike were chosen for the accompanying cross Section. An east-west strike, accompanied by strong anomalous dips of fifteen to twenty degrees to the north is indicated by geophysical data about five miles north of the cross section.
