The Homestake Airway Beacon sits on the boundary line between Jefferson and Silver Bow counties, Montana about six miles southeast of the City of Butte, the Silver Bow County seat. Erected in 1935, the beacon was part of an historic system of lighted beacons that provided guidance to aircraft pilots as they flew both north-south and east-west across Montana during nighttime. The beacon is at the junction of the National Parks Airway route between Salt Lake City and Great Falls, Montana, and the Northern Transcontinental Airway cutoff between Three Forks and Gold Creek, Montana. The Homestake Airway Beacon functioned as a critical component of both airway routes in Montana. A metal platform surmounts the 15-foot steel tower and provides access to the revolving beacon at the top. Formerly powered by a gasoline-fueled generator, the beacon now derives power from a Northwestern Energy power line. The generator and fuel tank were removed from the generator shed sometime after 1960. The generator shed is accessed via a Forest Service road branching off Homestake Road. The road is accessed off the Interstate 90 Homestake Pass Interchange (#233) and is only accessible by foot. The Homestake Airway Beacon sits within the Section 7 page 4 United States Department of the Interior National Park Service / National Register of Historic Places Registration Form NPS Form 10-900 OMB No. 1024-0018 Homestake Airway Beacon Jefferson & Silver Bow, MT Name of Property County and State Beaverhead-Deerlodge National Forest and is maintained and operated by the Montana Department of Transportation’s Aeronautics Division. The Homestake Airway Beacon retains a very-high level of all aspects of integrity including the virtually unchanged setting since the beacon’s construction in 1935. ______________________________________________________________________________ Narrative Description The Homestake Airway Beacon sits atop a granite outcrop of the southern Boulder Range at an elevation of 7,200 ft., literally on the crest of the Continental Divide at Homestake Pass. The outcrop rises nearly 700 ft. above the surrounding terrain. Interstate 90 crosses Homestake Pass east-west about one mile to the north, and Butte, Montana lies six air miles to the northwest and is visible from the tower’s platform. The beacon straddles the Silver Bow-Jefferson county line and the Continental Divide. A dirt road approaches the beacon’s generator house from the north and west, providing vehicular access to that feature; the tower is accessible by foot from the generator house. The vantage of the Homestake Airway Beacon features spectacular views of the Silver Bow Valley and Butte to the west and the Jefferson Valley to the east. The Continental Divide stretches to the north and south and functions as the boundary between Silver Bow and Jefferson counties. The property occupies about three acres of Beaverhead-Deerlodge National Forest land on which the MDT has held a Special Use Permit since 1935.1 The Homestake Airway Beacon consists of three features: the beacon tower (F-1), the generator house (F-2), and power line. Homestake Airway Beacon Tower (one contributing structure) The beacon tower is comprised of steel angle sections, bolted at the connections. The tower stands 15 feet in height. It is 4½ feet square at the base with each corner resting on a buried concrete footing. The tower tapers to 16 x 16 inches at its top and partially supports a platform. Additional pieces of angle iron bolted to the upper tower legs also support the platform (this configuration is unique to shorter towers). The tower’s structural elements were fabricated by the Jones & McLaughlin
