- The contour interval is 100 feet.
- Point X is located at an elevation between 1600 and 1700 feet.
- Point A is at 900 feet, point B is at 800 feet, point C is at 1500 feet, and point D is at 1000 feet.
- The elevation change from A to B is a decrease of 100 feet.
- The distance from A to B is approximately 4.5 miles.
- The gradient from A to B is approximately 22.2 feet per mile (100 feet / 4.5 miles).
- Fish Creek flows from northeast to southwest.
- The steepest slope is found on the southeast side of Rock Mountain, indicated by the closely spaced contour lines between points C and D.
- The highest possible elevation of Rock Mountain is just under 1700 feet.
