These plucky US Forest Service Rangers patrolled the (fictitious) Sierra National Park where a typical day’s work might find them saving a group of climbers from a slippery rock wall, pacifying couples fighting over a campsite, and designing a bear-proof garbage bin (Cruncher was the park’s troublemaking bear).

Episodes showed the problems and satisfactions of supervisor Jack Moore (Jack Hogan) and his staff, consisting of rangers Tim Cassidy (James G. Richardson), Matt Harper (Ernest Thompson), P.J. Lewis (Michael Warren), and Julie Beck (Susan Foster).
Their problems stemmed from the conflict between preserving the wilderness’s natural beauty and accommodating the flood of tourists who wanted to use the park’s resources.
The campers, skiers, hikers, and climbers came in all shapes and sizes. Some were friendly, some stubborn, and some nasty and cruel.
Sierra debuted on NBC on Thursday 12 September 1974. The series was filmed on location, primarily at Yosemite National Park, in cooperation with the National Park Service.
