turtleback
Domed protective covering
A turtleback is a curved, convex surface resembling the shell of a turtle.
In architecture and shipbuilding, it describes a rounded deck or roof designed to shed water: The forward turtleback kept waves from swamping the vessel.
The term also applies to geological formations with similar domed shapes.
