Height and type: Sometimes listed as a 75-foot cascade falls, but there is over 100 feet of cascade from top to bottom
Water body: The stream is called “Jack Falls” as well
Access: There is a pulloff on Graham Road in Prescott just off of Highway 30. From there cross the highway with care (accidents are common in this area). Getting up to Old Columbia River Highway can be difficult, with both marshy ground and lots of brush in the way, and the old highway can be hard to find. The best way is to work your way northwest keeping the marsh/brush on your right and the steepest slope on your left. Once you find the long-abandoned highway, proceed north until you reach the falls.
Property status: City of Prescott
Notable Wildlife: terrestrial mollusks, woodland salamanders, northern red-legged frogs
Interesting History: In 1913 work began on the Columbia River Highway, and by 1915 it had reached Columbia County, finally allowing our cities to be connected by automobile. It started as a mere graded dirt road, but between 1917 and 1920 the highway was paved for the first time. The stretch of highway near Prescott passed under both “Jack Falls” and “Little Jack Falls”. Due to these falls and great views of the Columbia River, the locale became a minor tourist spot. There were even postcards made.
