The last easy part of hiking to C2. The camp is just over the serac on the left in the photo. Onwards to C3 it's also quite easy going, but there are some steeper sections, with 65-70 degrees. There's a "black dot" on the slope below the horizon. It's a climber on the last steep part to C3 at 6950m.
Gasherbrum III looming above.
