With a 2WD drive jeep cherokee, we made it to about 8,800‘ where you dip down and then the road starts to get nasty. Up to that point there was not really any snow. A stock 4WD of equal or better quality should be able to make it another 1/2-1 mile through mixed mud, snow, and rock.
The photo is the road 1-2 miles from where we parked. Someone with a 4 wheeler turned around just before this point. The trail is bootable w/o snowshoes almost all of the way to Lake Como and then there is a trench almost to blue lake that is nice to have snowshoes on.
