The Byrd Glacier in Antarctica creates a 100-mile-long, rock-floored ice stream. Pressure from glaciers and the ice shelf can force Antarctic water to flow uphill. (Photo: NASA)

This is not a riddle: Why would water run uphill in Antarctica?

According to researcher Robin Bell from Columbia’s Lamont-Doherty Earth Observatory, some Antarctic ice sheets sit two miles above rivers, squishing everything below them and squeezing water up the side of mountains — against gravity — for 60 to 70 miles. When the water gets to the top it freezes, joining the ice sheet on its slide down to the ocean.
