High Quality Content by WIKIPEDIA articles! A pack station is the base of operations for transporting freight via pack animals in the Sierra Nevada mountains. The station facilitates the transition from mechanized transportation to pack animals, and necessarily includes a corral for the animals and sometimes a stock loading ramp. In some places there may also be a barn or other structure to house feed and tack, and a loading dock or shelter for the items to be transported. In locations on private land, there may be a business office on site.
