up until Foley Lake, it is 2WD/low-mid clearance accessible with some careful driving -- saw a Tesla Model 3 that managed to drive up there without any issues

Just before North Foley Lake, moderate washout -- mid- to high-clearance

After that, high clearance 4WD/AWD, steep and narrow. Drove to 850m in Suzuki Jimny, where there was a muddy and steep section. RAV4 got stuck there, got through with traction aids and 4 people pushing. I couldn't get through it solo afterwards, even more torn up and muddy from them.

Road continues to be muddy, steep and require good clearnace until 900m -- from there to 1050, it is in much better condition and very dry if you can handle the muddy sections beforehand
