Clarence King, Geologist
May 2004 by Edgar B. Heylmun, PhD
Clarence King was born in Rhode Island in 1842, the son of a businessman. His father died when he was 6, so he was raised by his mother. She wanted to have Clarence attend the very best schools, and even moved in order to have him in the best district. She gave him a magnifying glass on his 7th birthday, and this led to his discovery of fossil ferns in neighborhood rocks.MMAC Update
We will be bringing the first of several bills that were requested by Congress during a previous MMAC trip and presenting maps depicting all the MMAC-assisted Mining Districts.

Gold in Panama
Panama is a long, narrow isthmus, 30,200 square miles in area, that separates Costa Rica from Colombia. It is best noted for the Panama Canal, which is now under the control of the Panamanian government, aided by the United States. The canal bisects the country and is an engineering marvel that was opened in 1914.
Nevada Looks to Tourism to Fill Mining's Gap
Lt. Gov. Lorraine Hunt and the Nevada Commission on Tourism have agreed to seek an unspecified amount of marketing funds to boost tourism in the Ely, Nevada area in the wake of a mine closing.
Residual Placers: An Often Overlooked Gold Source
Because the forces of erosion and gravity tend to carry lighter materials like quartz away more easily, the heavy minerals like gold or silver will tend to be concentrated in the general area around the vein outcrop. These concentrations are what make residual placers so attractive.
Multiple Use Lands, Symbiotic Relations and Conflict Resolution
The automatic discrimination and exclusion of man from nature, like his access and use of the land, presupposes man as a destructive force for change, absent a relative hard look at the natural forces of change. Setting aside lands for non-use does not encourage wise use symbiotic tenets, which man has traditionally formed in his coexistence with nature.
Placer Sampling for the Small-Scale Miner
I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.
