We appreciate your patience as our office continues to work remotely. We pick up Jr. Ranger booklets about 2 times a month and reply to them as soon as we can.
The Junior Cave Scientist Program is a part of the National Park Service Junior Ranger Program. The goal of the Junior Ranger Program is to connect young people to their national parks through a variety of in-park activities that are designed to introduce them to the national park system and cultivate future generations of park stewards. Programs range from simple scavenger hunts for younger children, to multi-day ranger-led activities. Over 200 National Park Service areas currently have Junior Ranger programs.
