Here, in the valley of Kaldalon, in NW Iceland, which I have visited many times, we have a text book example of knob and kettle topography. When we were working there, we referred to this as the Trout Pools area, since there were small trout in some of the little lakes in the depressions or "kettles".
Some authors use the phrase "kame and kettle topography" -- presumably in fear of getting into trouble with the guardians of public morality..........
Compared with the abandoned outwash fan on its SW flank, the Trout Pools area is extremely complex, with sinious esker ridges, mounds of sand and gravel, dry channels cut by flowing meltwater, and abundant hollows -- some containing pools or lakes, and some dry. Some researchers who have worked here refer to this area -- mistakenly -- as "pitted outwash". Especially on the eastern part of the discussed terrain there is much till (in patches or hummocks) resting on top of the fluviogloacial materials, and there are some distinct mounds of reddish "rhyolite till". It is clear therefore that at least some of the topographic features were formed sub-glacially -- and that some spreads of fluvioglacial sands and gravels were deposited on top of melting dead ice.
At the time of formation the ice edge must have been melting catastrophically from its maximum at the Trimbilsstadir moraine -- widely assumed nowadays as having been formed at the peak of the 1740 glacier surge.
I shall do another post on the surges and glacier snout oscillations .........
