Gold in the United States, exclusive of Alaska and Hawaii

Abstract

The accompanying map shows the distribution of the principal gold mining districts in the United States (excluding Alaska and Hawaii). Only those districts that have produced 10,000 ounces of gold or more are shown. Gold ore reserves were not considered, and the types of deposits are not shown. Based on total output, the gold-producing districts have been classified into three categories on the map: (1) those that have an output of 10,000 to 100,000 ounces, (2) those with an output of 100,000to 1,000,000 ounces, and (3) and those with an output of more than 1,000,000 ounces. Each category is represented by a particular map symbol, and the symbol is placed at the approximate center of the mining district.
