Q

On an Army Corps of Engineers navigation map, how is each mile A.H.P. on the Lower Mississippi River marked?

🔍 Key Concepts

• Army Corps of Engineers navigation charts symbology for inland rivers • Meaning of A.H.P. (Above Head of Passes) on the Lower Mississippi River • How river miles are typically labeled on U.S. inland river charts

💭 Think About

• Look at how distances are usually shown on river charts—are they displayed as symbols, as lines, or as text? • Think about what would be the simplest way for a pilot to quickly read river miles while underway. • Ask yourself: would a light or prominent structure be used to show each mile, or is it more likely a printed chart feature?

✅ Before You Answer

• Verify what A.H.P. stands for and that it refers to mileage along the river, not a buoy or light system. • Check an example of a Corps inland navigation chart legend to see how river miles are depicted. • Confirm whether mile markings are shown as symbols plus numbers or just a simple printed indication of mileage.
