Last thing was I entered a large dwemer room and was thinking, "Okay, wheres the trap". I continue into the large room and see no enemies, a small of light appears in the middle and I go to it ( I really don't know why it got me so easily ). I proceed to touch it then a car alarm like sound popped up then I am hurled down deep into the side of a mountain. Needless to say every time I get the chance, I get friends to go there and do what I did. You fall the longest fall in Skyrim I think, thing takes forever for you to land.
After reading the hint on page 3 that it is a ruin you can see on your compass from that barrow, I just had to go try and find this (it is Kagrenzel by the way). I did it off a save I didn't overwrite, expecting to die from the fall, but wanted to see it anyway. I found it, heard the alarm sound and after a short wait, the trap springs. I was reminded of Bill and Ted falling to hell and after a while of screaming, one of them says, "Dude, this is a seriously deep hole." Here's the kicker though, I lived. I maneuvered side to side to dodge some ledges along the fall (you know how you can do that without a jet pack) and fell all the way into some water. Right in front of me is this underwater chest with an expert lock. After the moment it took me to realize that the fall had ended without my untimely death, I naturally decide, "Ooh, treasure," and proceed to pick it because nothing gets your blood a boilin' for loot like an unending plummet through a shaft in a mountain. Thanks.
For myself, it will likely never be topped by the ancient dragon biting me in half ala Lui Kang fatality style. I was plucking at a grounded ancient dragon with my bow from behind the cover of one of those mound/stalagmite rock things as tall as a person out on the plains. I would sidestep to one side, fire off two shots until it inhaled, step back for cover at it's blast of cold breath, then rinse and repeat out the other side as it scrabbled across the ground towards me. Well, I neglected to notice just how close up to the rock I was and how my health had slid down into death animation range. It made it right up on the opposite side of the mound and all of the sudden out of nowhere, it snaked it's head up on it's neck over the top of the rock, reaching down to bite me in half. It made me, my cousin, and a buddy watching all jump in startlement it was so sudden. I couldn't stop laughing. It was death, but it was the coolest thing I'd done in the game to that point. It got tired of being pegged with arrows and recalled suddenly that it was three stories tall and didn't have to put up with that crap.
