There is something I cannot understand here. OSM shows a cliff around a glacier, but if I try to edit with iD I see only the glacier. If I try with JOSM I only see the cliff, but not the glacier.

There are a bunch of ways with the same problem around here. I don't know this area personally, but cliffs made this way don't seem to make a lot of sense.

The whole city area has been tagged as railway station. I could just change it to landuse=residential but I see there is other data attached. I suppose it has been set to railway station by mistake, so it would probably be better to restore a previous state but that's really beyond my reach. If someone knowledgeable is willing to do that it's probably better.

There is a mismatch in contour lines
