Caches around the mysterious lake (The Long Dark)

Please tell me how many geocaches? Found 6 geocaches, like all guides, I counted only 6, but the quest I have hanging as not completed, then caches any more, or I have a bug with the quest. The caches I've found are 1) hiding place, the passage of a mysterious lake to the lonely marshes, 2) hiding in the cave from the mysterious Alan lake, 3) a cache in the woods at a mysterious lake, and 4) hiding in the gorge near the railroad mysterious lake, 5) a hiding place under the roots of a tree in a lonely swamp, 6) the stash of an old hunting Lodge near the railway mysterious lake. If that is not enough, then tell me why, please. Don't want to leave Locke with hanging quest.
