The elevation of Granite Peak is 12,807 feet, and the depth of the cave is 60 feet below sea level.
To find the difference between the two, we can subtract the depth of the cave from the elevation of Granite Peak:
12,807 feet - (-60 feet) = 12,807 feet + 60 feet = 12,867 feet
Therefore, the difference between the elevation of Granite Peak and the depth of the cave is 12,867 feet
