Excerpt from Report on the Drake Gold and Copper Field
It is a difficult area to map accurately, t.e., in which to supply a connected sequence of geological events. Instead of containing several strong lines of rock junctions, whose succession in time might thus be readily grasped, it consists of a mass of insignificant and overlapping lava ¿ows, sandwiched in with which are certain fossil beds. Dense jungle growths are common, which still further complicate mapping work.
Several of the lava outcrops in this rough country were mapped in by Mr. Morrison, during my temporary absence in New England.
Drake, at present, is a very neglected field, a fact due, in great measure, to its complicated and minute structures.
