“Natural Bridge is an impressive natural rock formation that spans the flow of the Kicking Horse River west of Field, where the slower-moving waters from the Field valley flats begin their descent through a canyon to be joined by the Amiskwi River.”

“Sculpted by the erosive forces of rushing water over what had once been a waterfall, the Natural Bridge is a powerful reminder of how much influence water has in shaping the landscape. Softer rock found below the Natural Bridge’s hard limestone band eroded more quickly, and fissures in the rock widened until the flow of water was diverted below the outcrop.”
