A Search for Tantalum
July 2005 by Leonard MelmanIt is likely that few tourists passing through the crowning glory of the Canadian Rocky Mountains in northeastern British Columbia would be aware that this spectacular region is the focal point of the search for one of earth’s most intriguing metals—tantalum.
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
The remote desert of southwestern Arizona was an attraction only because of the gold and other minerals that were found there. Certainly the weather was not a draw! The early mining days were tough—the mines were a long way from supplies, and hostile Indians made travel in the area extremely dangerous.
America has lost another ex-president with the passing last month of Gerald Ford, the only non-elected president in history. It is worth remembering, however, that he came into the office under incredibly difficult circumstances and acquitted himself well. He will be fondly remembered.

As soon as reasonably accurate maps were made, 200 years ago, one could not help but note the parallelism of some coastlines with those on other continents. The coastlines of Africa and South America, in particular, are strikingly similar. The first scientist to write on the subject was an Austrian, Edward Suess, who put India, Africa, and South America into a supercontinent he named “Gondwanaland.” But, it was not until Alfred Wegener, a German, came out with his “Theory of Continental Drift” in 1912, that scientists took note.
A US Geological Survey (USGS) assessment of undiscovered oil and gas resources of the central part of the Alaska North Slope and the adjacent state offshore area finds that there is a significant amount of oil and a large amount of gas that remains to be discovered.
