Boneyard

A boneyard is a storage space for obsolete items.  Similar to the term's original meaning, a cemetery, boneyard refers to the storage or cannibalization of retired items and machinery with no utility.  Any useful parts are typically removed before being stored.  "Boneyard" and "graveyard" are often used interchangeably.

Commonly, boneyard is used to describe a scrap yard for heavy equipment, such as vehicles, aircraft, and trains.  In business, it is used to describe storage rooms for functionally obsolete computers, printers, and other business hardware.

Boneyards exist in many different environments. Items, either in whole or in part, may be stored there permanently or until transported for disposal. An example of a whole item stored in a boneyard is the antiquated pay phone.  An example of part of a system stored in a boneyard is the heavy, bulky computer monitor capable of displaying only limited information at low-resolutions.

The automotive and industrial industries saturate boneyards with obsolete items. These storage sites feature vehicles and other equipment that are no longer in working order but may have value as a source of spare parts.  Boneyards can also include parts stripped from the original equipment that may be useful to repair equipment in better condition.  Scrap metal boneyards may have items whose only value is in the material in which they were made, such as the aluminum in vehicle frames.

Some of the most notable boneyards include those used to store decommissioned aircraft. One of the largest within the United States is located at Davis-Monthan Air Force Base in Tucson, Arizona. The 2,600-acre property holds an estimated inventory of over 4,400 decommissioned aircraft.

In Las Vegas, Nevada, the Neon Boneyard houses a variety of neon signage that local casinos have decommissioned. While the facility functions as a storage site, it also functions as a museum. This allows the items to be shared with the public for their historical value despite their low functional value.
