I would have certainly imagined the weather would be so extreme it wouldn't be friendly to anyone!
Just found this link, have scanned the material very briefly and already learned there is a vast bunch of material ahead for anyone who's got the time to start the search! I saw this title:
'Surprise' find on Highland loch rewrites timeline of ancient water dwellers
Analysis of a loch in Assynt in Sutherland has transformed the understanding of how people lived in the far north-west of the Highlands following a surprise discovery.
The crannog at Loch na Claise has long thought to date to the Iron Age, from around 450BC, but analysis of sediments from the loch has rewritten the timeline of the site, with it now known there was human activity there during the Neolithic era, sometime around 3200BC.

Unfortunately, you must buy a subscription to read this "premium article."
It was so exciting for a moment, as I've run across other articles concerning communities of people who lived on the water, repeatedly, throughout the world, and they are always fascinating. Had no idea that happened in Scotland, or whatever it was called at the time!
Looking forward to the idea someday information will be published which will throw a lot of light on these cultures which became lost in time. Technology is making a lot possible now which was inconceivable in the past, with ground-penetrating radar, "LIDAR" and structures are coming into view in the desert, and under heavy vegitation, everywhere. We just might get lucky.
