Examined east end of Horst Basal cgl. of Lenox Hills is in contact with Neal Ranch shale at N end of valley in which igneous body exists. The shale occupies an elevation of 1 contour = 50' on west side valley but igneous body is in contact with cgl. at fault. The fault runs down west side of elliptical hill with a zone about 20' wide. A large baked zone is evident and the igneous body is in contact with the shale on the west side but tapers up to the cgl on the east. The elliptical hill is composed mostly of Hess limestone tipped up 50 - 60Â°. On the NE slope 80' above the road is a patch of biohermal limestone with Institella, probably overlying the Hess uncomformably as it does at King loc 104. No Institella was seen in the middle part of the elliptical hill but it appears on the south side (loc 724t) and extends some distance to the south
