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 along it until you reach the falls.

Interesting History: In 1913, work began on the Columbia River Highway. By 1915 it had reached Columbia County, allowing our cities to be connected by automobile. The highway started as a mere graded dirt road, but was paved between 1917 and 1920. The stretch of Columbia River Highway near Prescott passed under both “Jack Falls” and “Little Jack Falls”. This locale became a minor tourist spot due to these falls and great views of the Columbia River, and postcards were made.
More information and pictures of the highway and old falls, and what became of them, is in our post “Old Highway 30 and Little Jack Falls“.

It’s a nice waterfall! As of March 2023 there’s a rough but very helpful path close to where you cross the highway, just across from Graham Rd, that leads to the abandoned highway.
Yes, it seems like over time that path is becoming easier to see.
