Liam is hiking up a steep mountain and reaches an elevation of 1,000 feet above sea level. After taking in the breathtaking view, he decides to climb down 1,100 feet to explore a hidden waterfall in a valley. During his descent, he realizes that he has gone below sea level in the valley where the waterfall is located. Although he has moved down 100 feet, his elevation is now at -100 feet compared to sea level.
