Mammoth Cave National Park

Mammoth Cave National Park has completed its visitor center renovation and exhibit installation and is inviting the public to take a look. An open house is scheduled for 3:30 pm to 5 pm Tuesday. The park says Phase I cost $6 million, provided from park fees, and included demolition of the administrative building to make way for a large lobby, information desk, ticket sales and restrooms.

The chief of interpretation at Mammoth Cave National Park has decided to hang up his Smokey Bear hat and retire. Mike Adams, who has been with the National Park Service since 1973, said the completion of the new Mammoth Cave visitor center prompted him to make the decision.

A veteran of the National Park Service who grew up in Kentucky's cave country has been chosen as the new superintendent of Mammoth Cave National Park. Sarah Craighead, who started her career with the National Park Service at Mammoth Cave in the 1970s, will begin her new post Nov. 4.

Mammoth Cave National Park is making use of some new propane-fueled vehicles, thanks to a partnership between the National Park Service and the Department of Energy's Clean Cities Program. The vehicles are helping to reduce greenhouse gas emissions in the park.
