It is about four miles (6 km) from here down the valley to the left to the glacier terminus, and more than six miles (10 km) up the valley straight ahead to the ice cap source.

The branch of the glacier to the right is interesting because it blocks a side valley and impounds a small lake known as Summit Lake. Or at least it used to. The shrinking glacier has become thinner and lighter in recent years, and early every summer now it floats up a bit and the lake empties out underneath the glacier to the Salmon River (left) in a sudden flood known by the Icelandic term of jökulhlaup.
