The cabin can be found in a small clearing in the middle of a forest of sequoia trees, on the slope of the mountain. In the mission Badlands, the cabin is used as a Witness Protection safehouse by the FBI. After that mission, however, the cabin remains completely abandoned. The cabin easily captures player's imaginations due to the cabin's isolation on the slopes of Mount Chiliad.
This is one of the top places to find the mythical Piggsy as the creature has been reported here numerous times. Note that the Yeti and Bigfoot are located on the summit of Mount Chiliad rather than on the slopes. This triad of creatures are dangerous and are said to attack players unprovoked. There are rumors about screaming sounds in the area well.
