Well, on the other side - here is just about the stupidest "off-road" video I've seen:
https://www.youtube.com/watch?v=2I_yz80B6Lo
One evening back in 1989, we drove up the west side of Tincup Pass in our 1965 C/10 (230-6 & four speed). Funny thing was we met a young couple in a 1969 Impala coming down. They scraped a little the first 1/4 mile down the west side, but going up the east side they had no idea any of it wasn't suitable for cars.
Of course I had been over it many times before that so I knew exactly what to expect. One time I took my stock 1973 K/20 up "the hard way" and it was a bit exciting but really the truck rolled right over the rocks like it was no big deal. I guess it is worse now.
It's weird to watch this video now because this area was literally my back yard for quite a few years
Edit: also,
that's not a shelf road
