Ranger Erik Ledbetter, Seneca Creek State Park, has agreed to lead our December 3 Frostbite Hike to the Seneca Quarries, which provided the stone for the Smithsonian Castle and many buildings around the Washington, DC area.

Meet at Rileys Lock (Lock 24, mile 22.82) for a guided walk to the quarries. The natural surface trail can be overgrown, so be prepared. For more information Pat White at 301-977-562 or hikemaster@candocanal.org.
