Hoover Dam

Today I only had a leisure recovery ride to do. So my parents and I went cruisin' around Lake Mead, over a little hill, through several tunnels, then down another hill to pay the Hoover Dam a visit. This thing is just simply huge, 726.4 feet tall, the base is 660 feet thick and tapers to 45 feet thick at the top. In 1931 5,000 men started working on building up this structure to tame the Colorado river (which also runs through the Grand Canyon) and turn it into a lake. It took them 5 years to complete.
