Boundary Falls, Waterfall at Boundary Creek, British Columbia, Canada.

Boundary Falls is a waterfall on Boundary Creek, a tributary of the Kettle River, located in a small canyon a little over halfway between Midway and Greenwood in British Columbia. The creek drops about 40 feet (12 m) over the brink, a couple hundred feet below the head of the canyon. The falls are easily viewed from the canyon rim, and the base can be reached by carefully climbing down the steep canyon walls.

Boundary Falls was settled in 1890 by a large group of miners drawn by mining opportunities in the area. They built a smelter, finished in 1901, which was shut down in 1902 by high operating costs, coke shortages, financial difficulties and low copper prices, and closed for good in 1907. The remains of an old dam that generated power for Greenwood lie about 100 feet upstream from the brink of the falls.

The falls gave their name to the small settlement beside them, which grew around a smelter completed in 1901. Slag piles from that refining and power-generating operation remain today, while the falls themselves lie outside Boundary Creek Provincial Park.

The upper viewing area is easily reached, though getting to the base requires careful climbing through steep canyon walls. Wear sturdy footwear and move cautiously when exploring the lower sections.

About 100 feet upstream from the brink of the falls stand the remains of a small dam that once generated power for Greenwood. The falls themselves drop roughly 40 feet, and the town beside them, also called Boundary Falls, took its name from the water.
