Jeremy, eight years old, and Peter Rush, six years old, have become the youngest brothers to complete the Junior Ranger programme at all the 63 US national parks and 108 other NPS sites. Their journey began in 2020 at Death Valley National Park when they were just three and one years old respectively.

The Junior Ranger programme involves completing activities, sharing answers with a park ranger and earning a badge and certificate.

Their father, David Rush, has submitted their achievement to the NPS and Guinness World Records for official recognition. •
