Iron Mountain is included in the Marquette television market, NBC affiliate WLUC operates a local news bureau covering the city and neighboring areas. Due to distance from the transmitters and topography in the region terrestrial television signals are very limited in the area with the strongest signal coming from Wisconsin Public Television translator station W30DZ originating from Fence, WI.
Historically Iron Mountain was served by full power station WDHS which intermittently carried a religious format between long periods of silence, translators of various stations originating from Green Bay, and a handful of encrypted cable channels broadcast over the air.
Iron Mountain's abandoned Millie Hill mine is home to one of the largest bat hibernacula in the Midwest. Roughly 25,000–50,000 bats make their winter home there.
Menominee Range
Geologic map of the Iron Mountain area
Iron Mountain is located within the Menominee Iron-Bearing District, which covers southern Dickinson County and extends westward into Iron County. Iron ore was discovered in Dickinson County in 1849 and Iron County in 1851. Ore is produced from the middle Precambrian Vulcan Iron-Formation around Iron Mountain, and the Riverton Iron-Formation between Iron River, Michigan and Crystal Falls, Michigan. Both formations belong to the Marquette Range Supergroup. The Vulcan is between 300 and 800 feet thick and consists of hematite and magnetite with quartz, while the Riverton is 100–600 feet thick and consists of siderite and chert.[15]

Train
Soon after this area was settled the news of mineral riches brought the railroads. First was Milwaukee Road, then Chicago & Northwestern and Wisconsin and Michigan. The W&M Railroad, after its abandonment was approved ended all service in 1938.[20]
The thriving of automobile usage in the 1950s caused the rail passenger usage to wain, and the Milwaukee Road discontinued the Chippewa passenger train altogether on February 2, 1960.[21][22][23] With few riders remaining, the Copper Country Limited made its last runs on March 7, 1968.[24] The C&NW also discontinued its service to Iron Mountain in the early 1960s.
Although there is currently no direct rail passenger service to Iron Mountain, Amtrak Thruway Bus Service connects to Marinette, Wisconsin.[25]
This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Iron Mountain has a humid continental climate, abbreviated "Dfb" on climate maps.[27]
