Ammonite Falls is one of three significant waterfalls in Benson Creek, in Mount Benson's northwestern foothills. This is a vertical place, its cliffsides studded with oceanic fossils.
Ammonite Falls is named for the fossils that inhabit the stack of sedimentary layers of rock kept slick by the falls. A brief foray into the rock matrix in the Benson Creek Falls Regional Park reveals a vast number of concretions, ball'o'fossils that can be broken open to reveal ancient life.
