These are the remains of two old cars (1950's or so) which are lying on their sides off Cardwell Hill Rd. From the looks of things, I wonder if there was some sort of race going on and both drivers lost control down the hill. This road is now just a trail but has a history of use ( http://therighttrail.org/trails/fitton-green-cardwell-hill-road-trail ). There isn't much left of these two cars. I was using my 170 degree wide angle lens on my iPhone.
