Camp Hancock preserves part of a military installation established as Camp Greeley in 1872 to provide protection for work gangs then building the Northern Pacific Railroad. The camp's name was changed to Camp Hancock in 1873. A log headquarters building still stands on the site; it has been enlarged and remodeled several times, and the logs have been concealed by clapboard siding. The building serves as an interpretive museum for artifacts and information about local history.
Volunteers will plant trees, trim existing trees, move flower beds and replant flowers.
