Mills Kelly, professor of history at George Mason University in Fairfax, will discuss his book, Virginia’s Lost Appalachian Trail, May 23, a Tuesday, at Christ Lutheran Church. His talk is at 7 p.m. He is director of the award-winning Roy Rosenzweig Center for History and New Media and a lifelong hiker. Mills also hosts The Green Tunnel Podcast on the history of the Trail.

This is the last of the spring Kegley Lectures sponsored by the Historical Society of Western Virginia (HSWV); they resume in the fall.

According to the book, the Trail was moved more 50 miles west, bypassing some beautiful landscapes. Kelly tells the story of the section that was lost.

Mills has been a volunteer on the Appalachian Trail for many years and currently maintains the Manassas Gap shelter in Linden, Va., one of the most historic shelters on the entire trail.

The church is at Grandin Road and Brandon Avenue in Southwest Roanoke. Admission is $5 for nonmembers of HSWV; members get in free.
