Rainbow Mtn

-15 at car. Alpine inversion -5 @ 1900m. Terrible skiing below Hanging lake. Lots of walking required on the way down. Great skiing above. Heliskiing traffic running all day, skied out everything outside the watershed. Turned around at 2100, strong northerly winds scoured the summit block. No results on hand shears. Small sluffs off steep, southerly rocky terrain, did not pull anything with it. Sharks still out & about.
