Active Drumlin Field Revealed at the Margin of Múlajökull, Iceland: A Surge-Type Glacier
Recent marginal retreat of Múlajökull, a surge-type, outlet glacier of the Hofsjökull ice cap, central Iceland, has revealed a drumlin field consisting of over 50 drumlins. The drumlins are 90-320 m long, 30-105 m wide, 5-10 m in relief, and composed of multiple beds of till deposited by lodgement a...
