Walking to 447 is 3.5 miles, if I did not have a vehicle then it would be the easiest option for egress.

Last time I was there in the rain I remember walking was quite difficult since every step added 4-6 inches to your height.

Can you make a snowshoe like device to help with this? Not saying to do so and hope everyone comes out merely a bit dirtier than normal.

Snow doesn't stick to your shoes the same way mud does. Snow shoes are meant to distribute your weight over a larger surface area to prevent you from sinking down. With mud, it's not so much sinking down as it is clinging to your shoes.

plastic bags, duct taped to your ankles is best

Don't walk in the mud. Or do, and be laughed at / cajoled by everyone else.
