Kirwin, ghost town in Park County, Wyoming, United States

Kirwin is a ghost town in Park County, Wyoming, at 2,800–3,000 metres in the Wood River Valley below Mount Crosby. A log building with a dirt-weighted roof and two metal chimneys stands near a taller light wooden building with a gabled roof; a log structure with a rust-patched metal roof and a green-panelled tower stands among evergreens.

Kirwin was founded in the 1880s after William Kirwin discovered gold and silver, which quickly drew prospectors to the area. A major avalanche in 1907 killed three miners and accelerated the town's decline as mining operations became less profitable and many residents left.

The town takes its name from William Kirwin, who discovered gold and silver while hunting on Spar Mountain in the 1880s. The abandoned structures and mining equipment speak to the hard work and dreams of the miners who came seeking fortune in these mountains.

Reaching Kirwin requires a four-wheel-drive vehicle since the mountain road is rough and steep, crossing streams and rocky slopes. Summer offers easier access, and visitors should bring sturdy footwear and water while taking care around deteriorating buildings and open mine shafts.

Renowned aviator Amelia Earhart visited the nearby Double Dee Dude Ranch and had a cabin constructed for her before her mysterious disappearance in 1937 during a flight. Remnants of that cabin still stand about one mile from Kirwin, linking the site to one of aviation's greatest mysteries.
