I would like to clarify the avalanche control strategies and restrictions
for Bourgeau Left hand and Right hand.
Parks Canada only does avalanche control control on avalanche paths that
affect roads.
Bourgeau Left Hand is not one of those paths and does NOT get
controlled (contrary to what is stated in early editions of the
guidebook)
Bourgeau Right Hand very rarely affects the parking lot and therefore
very occasionally gets control.
Avalanche control in the area can easily cause sympathetic avalanches
on Bourgeau Left Hand and Bourgeau Right Hand. A sympathetic avalanche
is one that occurs when another avalanche is triggered on a nearby path.
For this reason, Parks Canada closes those two ice routes to climbing
when avalanche control is planned.
