The fire marshal in West Virginia says a fire that heavily damaged the Point Pleasant River Museum was likely accidental.
News outlets report the fire broke out Sunday in the Point Pleasant community. No injuries were reported.
Authorities say more than 100 first responders arrived at the scene.
The cause remains under investigation, and no estimated damage estimate was immediately available.
Officials say community members and museum workers were able to save nearly 60 percent of the historic items in the museum.
The museum focuses on river life and commercial enterprise on the Ohio and Kanawha rivers, according to its website. It says the museum has been open to the public since 2003.
