I will be honest.
I lived at the foot of this mountain for awhile just before I head north to mountains twice as high in Whistler about an hour N. of here.
Locals told me more than once, people die climbing this hill in all seasons, on Grouse and they have to send out rescue crews and helicopters regularly to find them, pull them out --- sometimes not alive.
Climbing some of these mountains is quite risky. But sometimes I wonder "what is like without some risks?" After thinking about that I perform the action on my mind. Hope you had fun there?
