Got to within a stone's throw of the Hidden Lake Lookout trailhead. Stopped by avalanche debris at 3500ft which we tried to dig for a bit and drive over but a catastrophic vehicle slide was just looking too likely and I backed off.
The snow was absolutely awful, probably the worst I've ever driven. Even with tires only sinking in 6" fully locked at 1PSI I couldn't move on flat ground for the last half mile. The maximum snow depth was probably 1-2 feet. Took several hours of ramming to get up and much kinetic recovery getting turned around.
