I've never ever seen anyone ever mention the mammoth stuck in a glacier. I forget where exactly it is. But I know there is also a Dwemer ruin that has also been swallowed by the glacier. The mammoth has arrows and axes stuck in it. And if you climb on top of it there are all kinds of bones is it.
Totally and completely this. It's been pinned to the wall of the ice valley; what in the bejaysus could do that? The first time I came across it I was expecting some terrifying über-boss to appear and mess me up, but nothing happened. Is there any lore on what went on with that mammoth?
Weird stuff: struggling up that huge steep river gorge from the coast all the way to Ivarstead, there is a point where a fallen tree lies across the river as a bridge. One archer was crouching in the middle of it, waiting. A baddie? I dug out my long neglected Detect Life spell, and he was indeed up to no good. I skirted round, got up to the same level as the tree-bridge, and let him make his move. One arrow dodged, I hit back with a Thunderbolt, and blasted him clean off the log into the gaping valley below. EASILY 100ft down, onto jagged rocks. OK, forget him....wait, why is there a red dot on my compass? He survived that fall?! Beyond weird, and heading for ridiculous.
