I have generally used the valley/ridge system to get orograraphic lift to help lift me up to the pass when heading west with prevailing westerly winds.
I looked at the sectional for British Columbia and Alberta and was shocked. From Grande Prairie to Vancouver, you could get stuck in a major drainage going on a nowhere near your desired track flanking move for many, many miles finding a valley ridge system to a pass. Maybe on a 1/25000 topo I will be able to find some help.
It looks like someone pulled a massive harrow (multiple furrow digging farm implement) down the Canadian Rockies creating parallel canyons. Was that glaciation or wavy fold and fault?
Anyway I will get an education, and perhaps stuck in the first canyon.
