A glacier does flow “downhill”. which is correct about the hill? the glacier flows from north to south; we all know that maps have north at the top and south at the bottom, so this is the “hill”. the glacier flows from where snowfall is high to where snowfall is low; the “hill” is the big clouds in the atmosphere that supply the snow. the glacier flows from where its upper surface is high to where its upper surface is low, and thus flows down the hill of the ice surface. the glacier flows from where hank hill lives to where homer simpson lives, and thus from texas to springfield, wherever that is. the glacier flows from where bedrock is high to where bedrock is low, and thus flows down the bedrock hill.
