You are designing a hike that starts at the top of a canyon, above sea level. You plan to stop at three locations: A scenic landmark, which is at sea level
A famous boulder, which is below sea level
The bottom of the canyon, which is 600 feet below sea level

Design the hike. Choose the location of each stop. Make a table that shows each location, the change in elevation from the previous location, and the elevation of each location relative to sea level. Show how you found the elevation of each location using integer addition. Graph your locations on a number line. Describe your hike, including the total change in elevation from the start of the hike to the bottom of the canyon.
