🔍 Key Concepts

• Lateral buoyage system on the Western Rivers and how green vs red aids are shaped and numbered • How daymarks on fixed structures match the color/shape system used on buoys in that same waterway • Meaning of "AHP (Above Head of Passes)" and how that confirms you are on the Western Rivers system

💭 Think About

• Ask yourself: On the Western Rivers, when you are proceeding upstream, which side are the green aids on, and what is their typical shape (square or triangle)? • Think about fixed lights along the bank: their dayboards/daymarks follow the same color/shape rules as the nearby channel markers—what color and shape would you expect on the side you are on at mile 522.5 AHP? • Eliminate any options that don’t match the standard IALA-B shape convention for lateral marks in U.S. inland waters (green vs red and square vs triangle)

✅ Before You Answer

• Verify which side of the channel Walnut Point Light is on and whether that side is marked by green (port) or red (starboard) when going upstream on Western Rivers • Confirm in your notes which shapes (square vs triangle) are used for green vs red lateral marks in U.S. inland waters • Double‑check that diamonds are or are not standard shapes for normal lateral daymarks in the U.S. system; if they are unusual, consider crossing those options off first
