The frozen world at the edge of the Horseshoe Falls, Niagara Falls. I always enjoy the view of the frozen trees at the very edge of Niagara Falls. Talk about being hardy. Here, I arrived just in time to catch the last light of the setting sun trying to pierce through the dense mist rising from the waterfall and wrapping everything in ice, including trees, railing, people, and cameras!

The Horseshoe Falls, frequently referred to as the Canadian Falls, located partially in the United States and partially in Canada, is where most of the Niagara River flows and falls down. In its center, water rushes at 20 miles per hour and a depth of almost 10 feet. The tallest point is 174 feet, and the depth of the river at the base is 184 feet. This wonder of nature is a good example of how much impact people can have - the volume of water is highly regulated by the two hydroelectric power plants, with the most volume going over in daytime during the peak of the tourist season.
75,750 gallons (286,744 liters) of water per second flow over the American and Bridal Veil Falls and 681,750 gallons (2,580,704 liters) per second over the Horseshoe Falls.
