With Hand Written Notes Relating to the Bullock Group and McIntyre Group
The map, titled The Mother Lode in Amador County, California, was compiled from official and private surveys by R.F. Morton in 1910.
The map shows the location of key mining claims and operations across Amador County. The map highlights the positions of major mining groups such as the Kennedy Mine, South Eureka, and Argonaut, among others, along the famous "Mother Lode," a rich vein of gold that runs through California.
The scale of the map, as noted, is 1 inch to 4000 feet, and it provides detailed information on the geographical distribution of mines, townships, and key geographical features like creeks and roads. It spans from Eldorado County to the west, through Amador County, and touches on Calaveras County in the east, offering a comprehensive view of this vital mining region during the height of its activity.
Color-coded sections delineate different mining claims and companies, with each company or group clearly labeled. These include well-known mines like Keystone, Wildman & Mahoney, and Zeile, providing a clear illustration of their respective locations in relation to natural landmarks such as creeks and roads. The map also indicates the depth of mine shafts, marked by small black squares, showing the extent of underground operations.
