Operation PALACI is the world’s largest mobile avalanche control program. Designed to keep the Trans-Canada Highway and the Canadian Pacific Railway open where they cross the Selkirk mountains, Parks Canada avalanche forecasts guide Canadian Forces artillery blasting of suspected avalanche paths high in the surrounding mountains at Rogers Pass. Command is provided by Joint Task Force Pacific in Esquimalt, B.C. Regiments of the 1 Royal Canadian Horse Artillery (RCHA) use modified 105-mm howitzer canons to fire from 18 positions along the Trans-Canada Highway. With an average snow accumulation of 12 meters, Rogers Pass contains over 130 avalanche paths that intersect the Trans-Canada highway and the rail line. Parks Canada and the Canadian Forces have been working together since 1961 to ensure safe Winter travel for people, goods and services along this vital economic transportation corridor. Canada officially adopted the C1 105mm Howitzer as a replacement for the 25-pounder Gun on 11 Sep 1956. The weapon was an adaptation of the US-designed 105mm Howitzer M2A1. The Canadian Army continued to use the C1 Howitzer unaltered from its original M2A1 configuration until 1997 when a modification was made to extend its service life. The new weapons were designated the C3 105mm Howitzer, and included a longer barrel, muzzle brake, reinforced trails and the removal of shield flaps.

Fonction

Used in avalanche control. The live round from this used and empty shell casing was fired by a Canadian Forces C-1, 105mm Howitzer canon during the Winter 2011/12 at the upper slopes and mountains of the Selkirks where the Trans-Canada Highway intersects Rogers Pass to prevent huge buildups of snow which could avalanche and close the highway and rail line.

Technique

During the winter 2012/13, the 1 RCHA fired 411 rounds that caused 245 controlled avalanche slides.
