Kaldalon -- the 1820 surge?

 

Traces of the 1820 (?) morainic loop on the floor of the Kaldalon Valley.  These are in the form of low elongated ridges and hummocks, quite subtle but nonetheless noticeable when one walks along on the valley floor towards the glacier.  The kame terrace remnants on the valley side above must be unrelated.  They may be related to the 1780 surge for which no terminal moraine is known (it may have been buried beneath the accumulating sandur).

The photo below (taken from high on the valley side) shows the degraded terminal morainic ridge with a couple of small "inliers" in the sandur, surrounded by gravel and water, further out.
