Both ice and water sculpt the landscape surrounding Columbia Glacier.  Since USGS studies began in the early 1970s the glacier has lost 140 cubic km of ice, thinning by over 500 meters in the neighborhood of this image, and exposing 100 square km of new ocean.

This photo is of the Bass Harbor Head Lighthouse in Acadia National Park, Maine at the southern tip of Mount Desert Island. Heres, waves from the open ocean, beating against the rock walls with full force, have eroded a wave-cut platform of considerable size at the base of the sea cliff which is more visible during low-tides.

More than 110 sinkholes formed in the Dover area of Florida during a freeze event in January 2010. Ground water levels dropped to record-setting lows as farmers pumped water to irrigate their plants for protection from the cold temperatures. The sinkholes destroyed homes, roads and sections of cultivated areas.
