This time with video (hopefully)... I found a 5 meter resolution digital elevation model of a part of the Austrian Alps (Tyrol[1]) and quickly visualized the region around the aforementioned Hintereisferner glacier using my https://shadergraph.thi.ng/ editor. The glacier itself is visible in the bottom left corner of the cropped terrain. The picture I posted earlier[2] was taken just north-east of the valley confluence nearest to the glacier tongue. Neighboring Kesselwandferner and Gepatschferner (the largest of the remaining glaciers in the Eastern Alps) are visible too...
If you want to try it with your own DEMs, just drag the image (as PNG) into the browser window, then create shader nodes: Normal map, Ambient Occlusion, Bump and Multiply (and set respective inputs for each node/pass)
