🔍 Key Concepts

• U.S. Coast Guard Light List entries for the Mississippi River (Western Rivers system) • How light characteristics are written (color + flashing pattern + period in seconds) • Difference between flashing and group flashing lights

💭 Think About

• Which choices describe a single flashing light versus a group of flashes? Match that to what a terminal/wharf light usually uses for identification. • Think about standard patterns for private aids to navigation on rivers: what colors and periods are most often used to mark structures along the bank? • Ask yourself which option looks like it would most clearly distinguish this terminal from nearby lights on a busy river reach.

✅ Before You Answer

• Verify in the current U.S. Coast Guard Light List for the Mississippi River the exact line for: "Bunge Corporation Terminal Lights (2) mile 570.6 AHP". • Confirm both the color (red, green, or white) and the period (4, 5, or 6 seconds) listed there. • Make sure you are not confusing a group flashing characteristic (like Fl(2)) with a simple single-flash characteristic (Fl 4s, Fl 6s, etc.).
