Thanks, Randy, and thanks for your email about slides to digital conversion. It was very helpful. I have a lot of old kodachrome slides of my parents and grandparents from the 50s-70s. Probably more sentimental than artistic value, but important nonetheless. I appreciate your hints and thoughts.
The white water in the foreground is a "low head" dam about 10 feet high. Most Pennsylvania rivers big and small have several of them along their length ranging from 3 - 12 feet. Most were for irrigation or creating a little extra height to run a water powered grain mill. Most were built in the 18-19 century and, of course, are no longer used. Even small ones are very dangerous because they create an undercurrent at their base that is very difficult to escape. Unfortunately, every year there is a report somewhere in PA of a drowning. For that and other reasons the state is working to remove them. A long, slow, and expensive process.
