Hanford: Junior Ranger Park Explorers

Manhattan Project National Historical Park rangers and REACH Museum educators partner up to bring Junior Ranger Park Explorer programs to different neighborhood parks in Richland throughout the summer. This series of free programs engages families and children of all ages in activities that explore Richland’s nature and history at different parks.

Many of these parks were created during World War II when the Manhattan Project developed a community for its professional workers that included green spaces for people to enjoy. Other parks, like Howard Amon Park, predate the Manhattan Project, but served as an important gathering place for the community during the Manhattan Project and beyond. 

Children can earn a special junior ranger pin by attending at least two of the three programs and completing the corresponding activities in the Junior Ranger Park Explorer Passport booklet, which will be available during the programs.
