Hoover Dam Turned Colorado River
In addition to the Wheeler Survey Group’s discovering the Rocky Mountains and southwestern states, and the New Mexico Old Mission Church, there are lots of other significant, still-standing landmarks that frontiersmen discovered over a century ago. However, environmental changes happen over time, and this picture is a perfect example of that.

This photo-documented a waterfront along the Hoover Dam back in 1871. Believe it or not, this area is now part of the Black Canyon along the Colorado River. How crazy is that? It has been over a century, so it’s only natural for landmarks to adapt and change over time.
