Established on April 30, 1996 as a result of recommendations made in the Kamloops Land and Resources Management Plan.
This location, with its waterfall and high limestone cliffs, has long been an important area for native ceremonial, spiritual and sustenance activities. Rock pictographs and culturally modified trees are located within the park. The park also contains the culturally significant Three Sisters rock shelter. Please do not touch any pictographs as the natural oils on your skin will cause deterioration of the colour pigments.
Oregon Jack Park protects the limestone canyon and falls on Oregon Jack Creek. Old-growth Douglas fir grows on the steep north slopes, with wetlands and aspen stands along the creek above the Notch.
The area is noted for black bears throughout the park, and both moose and waterfowl in the marsh wetlands of the western section of the park.
