H4 Localities 103-104. Composite-starting in lower silt unit at W.end 103, where shaly silt shows jaspersite locally - can measure up to at least four. layer Z here, then carry to 104 and take it on up. The thickest exposure of banded unit is on ridge N. of 104. Here the banded is much more shaly & thin-bedded than to west. The phosphatic nodule layer is well marked throughout this area and serves as datum for making composite of several partial sections. #5 Locality 107. Control section, plus a better exposure of some 200t of banded beds in gulley at N end of exposure.
