Question 32 Deck General

The correct answer is B) statute miles. Distances on the Great Lakes System are generally expressed in statute miles, which are the standard unit of measurement used on land in the United States. This is because the Great Lakes are considered an extension of the land-based transportation network, rather than a purely maritime system. The use of statute miles, rather than nautical miles, is the standard practice for reporting distances on the Great Lakes. The other options are incorrect because: A) miles above the entrance to the St. Lawrence Seaway (MASLW) is not a standard unit of measurement for the Great Lakes; C) nautical miles are used for maritime navigation, but not for the Great Lakes; and D) miles above the head of the passes (AHP) is not a commonly used unit of measurement for the Great Lakes.
