“…a classic horn-shaped summit, which is notable for the frequency of its rockslides; the rockslides are audible to campers and are a source of much curiosity and interest.” (memo from BC Parks, file C.1.62).
Debris flows occurring on Klapperhorn Mountain pose a significant hazard to railway operations at the base of the mountain.
The mountain was once known as Hogan Mountain. “Dinny” Hogan was a railway contractor who in the 1910s operated a large camp nearby.
