Which type of ice is the most difficult to combat and presents the greatest hazard to shipping on the Great Lakes during the winter months?

🔍 Key Concepts

• Fast ice vs. pack/slush ice: how each behaves around a vessel and in narrow channels • Great Lakes winter conditions: where the worst ice problems usually occur (open waters vs. shorelines vs. harbors) • Ship handling in ice: which ice type is hardest to break, avoid, or maneuver through

💭 Think About

• Think about which ice type can trap a vessel by closing around it, rather than just floating past. • Consider which of these ice types is actually common and dangerous on the Great Lakes in winter, not in polar oceans. • Ask yourself which type of ice would give an icebreaker or commercial ship the most trouble in confined or shallow waters.

✅ Before You Answer

• Verify which option describes ice that is attached or relatively immobile versus freely drifting. • Eliminate any option that is not normally found on the Great Lakes in winter. • Consider which type can block harbors, channels, and restrict maneuverability the most.
