Abstract
  • This report deals with a group of mineralized areas containing Tertiary veins of base metal and gold,· which occur at intervals throughout the Cascade Range in Oregon. Gold was discovered in this region in 1858, only a few years after its discovery in southwestern Oregon, and an output of nearly $1,000,000, almost entirely in gold, has been recorded. The gold was mined largely from the weathered parts of the veins; placer production has been negligible. Other metalliferous deposits include nodules of native copper between lava flows, nodules of manganese oxides, and deposits of quicl{silver along the western margin of the Cascade Range.
