More cracks
Longitudinal crevasses on the Castner Glacier. These cracks often form where the glacier valley widens, increasing the tensile stress on the ice and run parallel to the flow direction. These are less common than transverse crevasses that run perpendicular to the flow direction and often occur where the glacier steepens (you can see a few transverse crevasses on the upper right side of this image).
