Transformers check-in location: Hoover Dam, a self-drive trip to celebrate the New Year

According to tradition, the whole month of January is the New Year. Hoover Dam, named after a president and a filming location for Transformers, is a place where every detail and screw of the dam is meticulously crafted, and most importantly, it's free to visit. Parking lots are set up along the road for everyone to enjoy the scenery, making it feel like a park. Hoover Dam is one of the most famous arch-gravity concrete dams in human history and also a world-renowned hydraulic engineering project. Many people actually learned about its existence through 'Transformers'. The Colorado River below Hoover Dam was once the deepest and most turbulent river in the United States. After the dam was built and the river was cut off, the water became slow and wide. The 5th photo is from a self-drive trip, providing some information for self-driving tours. Hoover Dam is located in the northwest of Arizona, on Interstate 93, about 40 kilometers southeast of Las Vegas. The dam site is at the border between Nevada and Arizona. Due to the one-hour time difference between Arizona and Nevada, there is a clock on each side of the dam to facilitate timekeeping for passersby. Hoover Dam is taller than the Three Gorges Dam (185 meters) and has a larger submerged area than the Three Gorges Reservoir, but its power generation capacity is only 1/20th of that of the Three Gorges. This is because the flow of the Colorado River is very small, only 1/50th of that of the Yangtze River.
