🔍 Key Concepts

• River miles (AHP) and how they are labeled along the river on the chart/map • The symbol for a U.S. Coast Guard facility on an inland river chart (usually a specific icon near a shoreline or landing) • How numbered grid/square references on your exam training chart relate to geographic features

💭 Think About

• First, find mile 362 AHP on the river. What nearby towns, bends, or landmarks are labeled there that can help you confirm the exact spot? • Once you locate mile 362 AHP, can you identify the Coast Guard facility symbol near that mile mark along the bank? Which numbered white square covers that exact symbol? • Check whether the numbered squares are aligned to latitude/longitude lines or simple grid lines. How does that help you be precise about which white square contains the facility?

✅ Before You Answer

• Verify you have correctly located mile 362 AHP on the chart before worrying about the grid numbers. • Confirm you are using the correct symbol for a U.S. Coast Guard station/facility, not another federal or local facility. • Double‑check the edges of the number squares to ensure the Coast Guard facility icon is fully inside one specific white square, not just near a boundary.
