No-key chests, Any links to maps or locations?

All of the chests there were recently reset that don't take keys. I know where about 4 of the supposed 12 are, and while I'm sure I have run across some others while playing through, I didn't really think about the significance at the time enough to mark down or remember where they are. Does anyone have a link to any maps or something that tells where they are?

They are nice and easy to jump on and run one or two when I don't have a lot of time to play, so I would like to figure out where they all are if possible.

Thanks for any help.
