I first took this work shop in 2009, then called "Urban Disturbance". Tonight and tomorrow night we'll be out and about Denver in the Dark.......Below a reprise posting of one of photos from the previous workshop:
Here you see a view of the new molybdenum mine (underground, buildings in the lower left corner), and the original open pit mine cut into the mountains above. For more on the mining history click here:
You may have heard about the extensive flooding in my area. I obeyed the law enforcement request to stay home and out of the way of first responders, so no dramatic images here..........but if you want to see more about what's going on check the photo gallery here, and videos here.
So why does the Zambesi River 'Fall' into such a deep, narrow crack in the Earth?
Well it literally IS falling into a crack in the 180 million year old basalts that cover the area. Part of the East Africa Rift System. As these basalts cooled they formed cracks or fissures. These weak zones are preferentially eroded to form the Falls. This is the most recent of perhaps 5 earlier water falls that have formed in the area, having an estimated age of about 100,000 years.
