A brutal winter’s worth of snow and ice is washing up on the beaches of Cape Cod in the form of enormous, iceberg-like boulders.

The giant, human-sized boulders of ice ran aground in Wellfleet, Mass., over the weekend. WBZ meteorologist Eric Fisher says it might be a “once-in-a-generation” event. We imagine Boston is hoping the same.

Fortunately temperatures have been on a slow increase over the past week in New England, and the boulders are already shrinking. But for a while there, Cape Cod Bay was looking more like the Arctic than the East Coast.
