We present the first general theory of glacier surging that includes both temperate and polythermal glacier surges. based on coupled mass and enthalpy budgets. Enthalpy (in the form of thermal energy and water) is gained at the glacier bed from geothermal heating plus frictional heating (expenditure of potential energy) as a consequence of ice flow. Enthalpy losses occur by conduction... https://www.bekindtopets.com/top-offer-Ariat-Jackie-Square-Toe-Cheetah-super-save/
