On Saturday, April 17, from 10 a.m. to noon, volunteers are needed to team up with the Friends of Fort Knox and the Civil War Preservation Trust to help clean the Civil War-era State Historic Site. The nationwide effort — dubbed Park Day — is underwritten by a grant from The History Channel. In 2009, more than 111 sites throughout the country took part in Park Day.

Park Day, now in its 11th year, is an annual hands-on preservation event created by CWPT to assist local groups with the maintenance of Civil War sites. Participants gather at the sites to help with activities that range from trash removal to trail building. In exchange for their hard work, volunteers receive T-shirts and have an opportunity to hear a local historian discuss the significance of the site.

Volunteers are needed to sweep, rake and ready Fort Knox for its opening May 1. For more information about Park Day at Fort Knox, call 469-6553 or e-mail FOFK1@aol.com.

Resuming in May, the Friends of Fort Knox will continue work on the Century and a Half Project, providing extensive masonry repair on the interior of the fort. Last year, the Friends were able repoint masonry repair on most of the ten casemate areas of the fort.

Individuals who would like to help the Friends in their ongoing mission to preserve the fort, learn about fort history, Friends’ 2010 special events or hours of operation for the Penobscot Narrows Observatory, are encouraged to visit the Web site at fortknox.maineguide.com.

Fort Knox is owned by the people of Maine and operated by the Maine Bureau of Parks and Lands.
