There are many hills and valleys on this 10 mile hike through the Canyon area. At the beginning of the hike he drops down 1,042 feet to a beautiful water falls. He wants to hike to the bottom of the falls, so he descends another 525 feet. What is the elevation at the bottom of the water falls?

5,314 – 1,042 – 525 = 5,314 – 1,042 – 525 = 5,314 - 1,567 = 5,314 – 1,567 = 3,747 feet
