Ranger Bill is a Christian radio adventure serial focused on the life and experiences of Park Ranger Bill Jefferson. Set in the small Rocky Mountain town of Knotty Pine, the show follows Ranger Bill, played by Miron Canaday, as he faces various challenges with his friends and colleagues, such as Stumpy Jenkins, an old-time ranger known for his marksmanship, Henry Scott, Bill's teenage ward, and Gray Wolf, a Dakota tribe member who brings both traditional methods and modern forest management to the team. The show often incorporates positive Christian values, while the characters tackle issues ranging from lost kids and elephant attacks to spacemen and hidden treasures in the Amazon.

In total, 206 episodes aired, with many being rebroadcast on Children's Sonshine Network and His Kids Radio.
