🔍 Key Concepts

• How distances are measured on most inland waters and rivers in the U.S. • The difference between a statute mile and a nautical mile. • Where the term Miles Above Head of Passes (AHP) is commonly used.

💭 Think About

• Think about whether Great Lakes distances are treated more like ocean/coastal waters or inland river systems. • Ask yourself where you have seen AHP used before—what geographic area does that usually refer to? • Consider which unit (statute vs. nautical) is more common for charts and regulations on the Great Lakes.

✅ Before You Answer

• Identify which choice clearly applies to the Mississippi River system, not the Great Lakes. • Decide whether Great Lakes charts you’ve seen use statute miles or nautical miles for distance scales. • Confirm which answer choice refers specifically to the St. Lawrence Seaway, and whether that matches “generally expressed” for the entire Great Lakes System.
