An oblique photo of a portion of the new rift on Petermann Glacier's floating ice shelf (straight feature near bottom center), and an older curved rift from the flank of the shelf near top center. The shaded feature near bottom center is a medial flowline, whose presence may exert a stagnating effect on the propagation of the new rift toward the older one. | NASA/Kelly Brunt
