Continental Drift
November 2003
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.

Gold Deposition and Gradients of Placer Streams—Part I
June 2012
When placer miners from the gold rush era began experimenting with the slope of their sluices, they must have pondered the ideal slope for trapping gold in a creek bed too. Logic suggests the same is true for streams...
