I've gone thru Swindler's Den at least half a dozen times, and each time I find an annoyance that no one else in this forum seems to have found. Which means stating this here is probably going to make me look pretty stupid when the answer comes out, but by this time I'm willing to look stupid to know the answer. Anyway, in Swindler's Den at the very east end, in the the side of the passageway that leads out of the kitchen/sleeping room, there is one of those rocks that are used in the game to block passages and such. I can see on the map there is a short passage behind it.
I've searched the entire cave for a lever, pressure plate, pull chain, or any other activation mechanism to make that rock drop into the floor, with obviously, no luck. Would some kind soul please tell me how to make that rock drop so I can see what's in the passage? Thanks.

I haven't seen this rock of which you speak, but I'm going to check right now.

It could be:

Is http://i678.photobucket.com/albums/vv146/gmosko/Skyrim/SwindlersDen.jpg the place you are referring to? I don't think that's a passage. It just looks like blind rock to me.

Is that screenshot (cute chick BTW ) standing where the pointer on the map is? I think I found it in my game.

I'm thinking he's looking at http://i1209.photobucket.com/albums/cc398/buckomccane/Skyrim/Swindlers_Den_01.jpg before that thing in my spoiler tag which is http://i1209.photobucket.com/albums/cc398/buckomccane/Skyrim/Swindlers_Den_Map_01.jpg.

IDK for sure because I've never been there before the thing.

Yes, she's facing a different way (was standing facing the rock when I took the shot of the map) but that is the spot.

You just like the corset cuirass.
That's just the entranceway to that little hallway my Nord lass is standing in, right? I didn't see any closed doorways in Swindler's Den at all.

OK, I found that spot.

I can make that armor (and worse or better depending upon your perspective. ) and improve it past the cap all day long on my Assassin Chick and, yes, it's 'nice', but I meant that the character has a pretty face.

I'm assuming when he/she refers to the "kitchen/sleeping room" he/she means the room with the rabbits, salmon, and pheasants hanging about. I don't have the game on now, but I think you were a room away. It does like kinda' obstructed hallway-ish though.

I've never been into Swindler's Den before that thing so IDK if the flooded area is ever closed off. I know that pic I posted is horrible, but you might be able to tell that at the top of the entrance it almost looks like a rock has been swung upwards, but is still partially visible. In that pic I'm actually in the room with the hanging rabbits et al. With all the frickin' views of this thread I can't believe no one else has offered any suggestions.

Edited for spelling.

Um. I was never in there. Sorry.
