Yellow circles are gold mines, hexagonal markers are PLSS sections that contain active placer mining claims, and blue markers with pick axes are district locations. Townships that contain both active placer claims and historical gold mine records are shaded in one of the following colors based on how many active placer claims are in the township: 1 – 10 claims: blue 10 – 50 claims: yellow 50 – 100 claims: orange More than 100 claims: redĪdditional images in this article will contain more data points. The California Gold Map will be used in this article to analyze regions of high gold potential by looking at PLSS townships that contain both historical gold mines and active placer mining claims, indicators that gold is being actively mined in these areas in modern times. WMH Gold Maps for Google Earth Pro are designed to locate areas with high potential for finding placer gold. This view was created by importing WMH Gold Map data to Google My Maps The map is rare on the market, this being the third example we have seen in the past 20 years.Shaded rectangles are PLSS townships in California that contain historical gold mine locations and active placer mining claims. Putting the best face on the situation, he wrote: `Towns have sprung up at all the principal mining centres, and trading establishments in them furnish all needed supplies of provisions, clothing, tools, and other necessities, at reasonable rates.'

This interesting map shows Santa Cruz County as `Branciforte' and contains numerous place names in the mining region. An important feature of the Gibbes map is that it is one of the first, if not the first, map of California to show county boundaries. Compiled in the Bureau of the Corps of Topographical Engineers. between the Mississippi River and the Pacific Ocean. For the northern part of the state it follows closely the large scale Map of the United States. This map is before the discoveries on the Klamath River and, except for the Feather River and its tributaries, has few place names north of 39 degrees n. It shows the state before Klamath County in the north, and Nevada and Placer Counties in the center, had been set apart and thus gives an earlier representation than the Butler map published the same year which shows these new counties. to a little above 42 degrees is, because of its large scale and clear markings in colors of the different counties, one of the most satisfactory of the early California maps. This map extending from 34 degrees 20 minutes n. Streeter (whose copy sold for $500 in 1968), noted as follows: Many mining camps are pictured, including Toualamne City, Empire City, Jacksonville, Downingville, Coloma, Buck's and Illinoistown. Gold production reached its peak in 1852, the year after the map was published. Gibbes' map was published within a year of California being admitted into the Union as a part of the Compromise of 1850. Gibbe's map of the Gold Regions was one of most fascinating early maps of the Gold Region and is also of particular note as perhaps the earliest printed maps to identify County Boundaries in the state of California.
