The terrain elevation in the area between Minot and Audubon Lake varies from what range in feet MSL?

• A. 1,500 to 2,000
• B. 2,000 to 2,500
• C. 2,500 to 3,000
• D. 1,800 to 2,200

Answer: (B)

Terrain elevation is the height of the ground above mean sea level, and reading it helps you gauge how much clearance you’ll need over hills and ridges. In the area between Minot and Audubon Lake, the map shows elevations roughly from 2,000 ft up to 2,500 ft MSL. That means the lowest terrain you’d encounter there is about 2,000 ft MSL, with higher ground near 2,500 ft MSL. The range 2,000 to 2,500 ft MSL fits the chart data, while the other options either imply terrain lower than what actually exists or omit the higher elevations shown. Always compare your planned altitude to the highest terrain in the area using MSL to ensure safe clearance.
