Howdunnit?

Go figure. When youíve given up, One Fly has the answer, or at least an answer. Iím not totally convinced, but any explanation at all is more than I have.

How wide are those marks? You need to know that to know if it's a tractor trailer rig or a car. Because a bearing or more likely, the pneumatic brakes could have locked up on the trailer or something like that and the marks might be from the trailer. My guess is that it involves a trailer maybe being pulled by a car and automatic brakes locked up on the trailer. The shoulder on the right looks steep so the driver may have steered over to the side without the steep shoulder to keep from going in that ditch. or just tried to slow down and the trailer wanted to keep going so it turned sideways. And the trailer could have easily turned sideways like that when being pulled by a car or a truck.

But if it was a four wheel car, beats me.

On the old Vail pass in the early 70s, there were some weird skidmarks.

Sort of oval and two sets. My boss at the time remarked on them several times when we dove over the pass together. I didn't have the guts to tell him that I had turned my truck around in two 360 degree turns. I was following a Coor's truck and the driver leaned out and signaled that I had room to pass.

A station wagon pulled out from a layby and was hauling. The Coor's guy just missed it. I spun my truck twice and when I slowed down, the station wagon was coming at me so I pulled forward so the front end of my truck was over the gorge.

I'd always said that if anyone was going to die from me driving crazy it would be me. The station wagon cleared my back end by inches, but nobody died. Then I pulled into the layby and puked my guts out.

I think the fact the grooves of the tires are not distorted where the direction change happens is key to figuring this out.

It may not be much but I do find things like this interesting.

Thanks for finding some merit in this as well Jerome!
