Another helpful snow related layer to use with Gaia is the one for snowmobile trails, it shows what is groomed and closed to vehicles. Now that it's April they will stop grooming and those roads will open back up but it's useful during the winter months to see what you can access. I had a trip planned into an area that only had low/moderate snow so should have been accessible in the Jeep but when I looked closer with the Snowmobile Trail Layer on 75% of it was groomed trails, glad I checked before heading out.
