I just came across a great link from a very interesting site. It covers so many topics that I didn't know how to best catagorize it, so I just started a new thread for it.

The Great Mirror - Great Mirror Photos, Captioned Pictures, Travel Gallery Images - is (according to the site) "a collection of over 10,000 photographs of cultural or humanized landscapes. Arranged geographically and captioned, all the photos and captions are by Bret Wallach, a geography professor at the University of Oklahoma."

Of particular interest is a page dedicated to the downtown section of OKC which focuses on the history and development of the Oklahoma River, the railway system and depots, and the I-40 re-alignment.

U.S.: Oklahoma: Oklahoma City: Water, Rail, Road

Tons and tons of great pics there, along with a good helping of history and historical context. Some of the pics are clearly pre-Devon, but as you go along, especially near the end, you hit some more recent pics including the Skydance Bridge, etc.

Really neat site.
