For those that are interested, a quick review of slush on the ice.
First of all, slush conditions is a bad thing never to be taken lightly. Real slush, not "slushy conditions", occurs regardless of air temperature and does NOT and will NEVER occur from melting snow. If the snow is melting and "slushy", nobody here even gives a half a hoot about it. Real slush occurs when there's too much snow on top of the lake ice (see #1 ). The weight of the snow pushes the ice down below the normal level surface of the water. The ice cracks due to bending (see #2 ) and the water heads up through the crack(s) to where it wants to be which is back to it's normal surface level (see #3 ). The water doesn't care if there's a ton of fresh powder snow up there, it just has to get back to level. As a result, it mixes with the snow usually in large pools on top of the ice but well below the top of that seemingly harmless, beckoning snow. Think of that clean white snow as the beautiful mermaid and the slush would be the ship-eating rocks just under the surface. As slush sits under the fresh, fluffy, undisturbed snow, it lies insulated from the -30 (and colder) degree temps and does not freeze until the snow on top of it has been compressed in some way. The three main ways that snow can be compressed are by: 1. human/animal disturbance, 2. warming air-temps which cause the snow crystals to break down and the snow to settle which makes it lose its insulation quality, and, 3. the heat from alien spaceship exhaust pipes which has never been proven, but the theory does have its believers. For right now, go with reasons 1 and 2. When the insulation layer is lost, the slush turns to ice and that's a good thing.
