This vibrant, blue meltwater pool appeared several miles up the Colony Glacier in May 2021. From the air, I noticed an interesting feature in the middle of the pond, but could not make out what it was. I really wanted to land and investigate. After a half hour of aerial scouting, I identified a landing zone with a possible route to the pool across the otherwise impassible glacier. After an hour’s slog, I made it to the edge of the pool. It looked so different from the ground. I discovered that the feature was a 10-foot-deep ice bubble that had risen up and ruptured just under the water’s surface.
