Keyhole Falls

Keyhole Falls is the unofficial name for the largest waterfall along the Lillooet River in British Columbia, Canada.

The falls are 115 feet (35 m) high and are a punchbowl type of waterfall.

[1] Keyhole Falls was formed when the Lillooet River was dammed with breccia from a Plinian eruption at the Mount Meager massif about 2350 years ago.

The thick breccia soon eroded from water activity, forming Keyhole Falls.
