Keyholed Ice Block

We passed this ice block keyholed in a crevasse on Svinafellsjökull, one of the glacier tongues on Vatnajökull in Iceland. I didn't get this shot right the first time, but we luckily passed it again a short while later. I stopped and took 2 HDR series of it, and the second one was right on. This is it, assembled with HDR Pro in Photoshop CS5.
