The Mighty Colorado River

Just past the western border of the park, oddly enough we hit the Colorado River. Mighty enough to have carved the Grand Canyon, it is now tamed and shuttled hundreds of miles into a concrete canal on the outskirts of Tucson. From its headwaters in the Rockies the river once flowed clear to the Gulf of California. Now it is diverted at such volume that it runs dry before ever reaching the sea.
