Thank you for the links, Jeff
Sadly, Podkrusnohori wasn't the only destroyed region in the former Czechoslovakia. There were other regions there that were heavily damaged either by reckless mining or by chemical pollution from many dirty factories, typically located on the rivers. Before the heavy industrialization, there were many coniferous forests, but they were all annihilated by the industrial pollution.
The photographs taken by Koudelka in early nineties are important documentaries of that destruction and captured at the peak of the industrial exploitation. After 1990, some of the most polluting activities were halted, but it took several years and a lot of confusion after the "velvet revolution" before the government initiated a gradual rehabilition of the "moon landscape" area. Fortunately, the region looks much better and healthier today (see the pictures in the link below). There are many new lakes, forests, and recreational areas, even some vineyards. It seems that the coniferous trees disappeared for good, most forests there today consist of deciduous trees and are home to wide variety of animals, birds, and plants.
