Well , I am almost 13,000 ft. ! How do I know that and what should I expect..? How the hell am I gonna set up a base camp in such deep snow..? Also BC ,Alberta Border "THE GREAT WHITE NORTH" . I'm several miles from the closest town , which would be "Dunster" ,and somewhere near the peak of MT. Robson .! I got my back-pack , me and all these WHITE TOPS JUST DIEING TO KILL ME..! I"m Polish and I got some Kool toys and know just what to expect.! Altimeter with barometer along with topo maps and compass , That's how I KNOW I'm at 12,972 ft. ..! If you can't read a map and can't relate data (Correlation) ability to understand this data , buy your toys and learn (How) on familiar terrain..! I got about 16ft. wind pack under my skis and know it could swallow me whole.! Cautiously with my left ski , I break the wind pack crust and stick my ski pole in that fracture to see by pressure if it stops ! .. If it don't , I move on and look for more stability . That means this snow is relatively new and unstable.! Or (Leeward) which I will splane near the end..! Hoo Yaa.! Pay dirt , Stability..! I got the weight of me (+) all my gear..! 300 lbs.(+)..! Probing . The ski pole stops and compresses the snow at about 4 meters , just shy of 4 ft. ..! Home , for a while anyhow.! So many (rules of thumb here) experience , logic , UN-common sense , I'm gonna take a break and continue tomorrow! Do I have any interests yet ? Is anybody out thar..? Dang , I spend more time "EDITING" my mistakes than I do writin this crap..! BAN GRAMMAR NAZIS'..!
