From 2004 to 2008, the former Mt. Whitney Power Company Substation was renovated into what is now the Exeter Historical Museum. It was a million dollar project, and would not have come to fruition were it not for a group of dedicated volunteers. The project was the culmination of 30 years of hopes and dreams of local residents who wanted a museum for the community. 
Inside the museum, visitors will see a variety of artifacts, all pertaining to the history of Exeter and Lemoncove areas. It also includes artifacts from the Yokohl and the Mineral King, including Conifer. 
Shortly after entering the museum, we had the opportunity to watch videos about the history of Exeter, and we learned a few things that we didn't know before, such as the great Mixter Building fire of 1992. There are 6 video displays downstairs. Each of them is worth stopping to watch. My husband also especially enjoyed the sheriff's display, which had artifacts dating back to the 1800's.
