The Point

The Point, Pittsburgh, PALock 4, Monongahela River, Charleroi, PAWondering what the background in the banner at the top of the page is?  Well, it's a collage of the "Point" in Pittsburgh, Pennsylvania where the Allegheny and Monongahela Rivers meet to form the Ohio River.  It shows the Point circa 1920.  The picture on the left is a contemporary view of the Point.  The picture to the right is of the US Army Corps of Engineers Lock and Dam #4 on the Monongahela River about 30 miles south of Pittsburgh near a town called Charleroi.

In addition to Charleroi, there is another town close to Lock 4 named Monessen.  Charleroi was home to a glass factory and takes its name from Charleroi, Belgium, which was a major producer of glass products...and a lot of the original glassworkers were indeed Belgian immigrants.  Monessen had steel mills and a cast iron foundry.  It is named after the Monongahela (i.e., Mon) River and Essen, Germany, which was at the time a major steel production center.  One of the major reasons for locating the factories along the rivers was the need for a low-cost, dependable way to transport the primary energy source needed to run the factories, which was coal.  Southwestern Pennsylvania also had large deposits of soft, or bituminous, coal, much of which was transported from the coal mines to the factories by river barge.  Hence the need for the locks and dams to make sure the river was navigable year-round!
