Slough Creek's East Creek den is a territory located just south of the words "Slough Creek" on the map. The territory resides within range of elk hunting grounds and is distanced from stranger wolf pack territory, and is one of two den sites that have a den set beneath the roots of a large tree, the other being Bison Peak Cutoff. It has a fair distance from elk hunting grounds and is the closest territory to the cattle ranch. It is under no threat from the nearby wolf pack territory; this means hunting elk will take longer, but you're not likely to be bothered by intruding wolves.
|“||Congratulations! Due to your great experience as a wolf, you have found this den site on East Creek. It lies far from both elk grounds and other wolf pack territories. It is a safe location, but you would spend more time traveling to elk hunts.||”|

- East Creek is known as the 'secret den' or Slough Creek by most players who do not know the den's actual name. This is likely because of its close proximity to the creek.
