Actual elevation as little to do with it. It’s the topography around the site. SLK is high up, but is in a relative bowl. So the cold just drains and sits in there over the lake area. Then you get a place like MQE that doesn’t radiate even at an elevation about mine, but they’re sitting above everyone else. Any cold developing from radiated heat loss from the surface drains down and away from them...probably mostly into the swamp pit at OWD. lol
