Nizina Glacier, Alaska Range
Nizina Glacier is a 36 kilometre long valley glacier in the eastern Wrangell Mountains. It has two major flow units: Regal Glacier descends from Regal Mountain (4220m), Rohn Glacier from a Mountain called President's Chair. Below their confluence, the glacier tongue is locally known as Nizina Glacier. In recent years it has formed, due to recession from a terminal moraine, a large proglacial lake into which it calves may large icebergs.
Confluence of Regal Glacier (left) and Rohn Glacier. The glacier terminus and proglacial lake are visible on the top.
Folding on Rohn Glacier due to longitudinal compression. Note turquoise meltwater pond on the far right.
Meltwater lakes and deeply incised meltwater channels on stagnant ice on the true left side of lower Rohn Glacier.
A meltwater stream from Frederiks Glacier flows towards the tongue of Nizima Glacier. Note older meltwater channels on the green hill in the left foreground.
The meltwater from Frederiks Glacier erodes the true left margin of Nizima Glacier.
Glacial lakes on the left side of Nizima Glaciers tongue. Note terraced alluvial deposits.
Prominent sand cone on the edge of one of the glacial lakes (slightly right of centre).
The disintegrating tongue of Nizima Glacier has calved many large icebergs into the proglacial lake.
