So, this is how the conversation went:
Superman: “I want to go to the calanques!”
Nancy: “What are the calanques?”
Superman: “ Fjords.”
Nancy: “What’s a fjord?”
Superman: “Fingers in a bay.”
calanques: a steep-walled inlet, cove, or bay that is developed in limestone, dolomite, or other carbonate strata and found along the Mediterranean coast. This calanque is Port Miou. Located in Cassis, 30 km southeast of Marseille.
