It seems that something went wrong with the elevation model of Greenland. Since a few days I have some caches of Greenland with anormal elevation values (like GC1Y8EH or GC2AGQQ or GC20EV9 - all in the same area of middle west Greenland)

Maybe this free elevation model of Greenland will be a better major source:

As far as I know PGC uses OpenTopoData.

The underlying data is an overview of manageable services. It is an existing dataset summary and seems to be the best for each area. Kartverket for Norway, LINZ for protection and EUDEM for Europe.

ArcticDEM strips of 5 meter mosaics across all of the land north of 60° latitude, including Alaska, Canada, Greenland, Iceland, Norway, Russia, and Sweden

So not PGC is responsible for the elevation data. It only uses the ArcticDEM for Greenland.
