the hill above is the one that eventually helped me flip my truck...although it was 6 mo after these pics and the rain washout made the hill much more trecherous...the rear slid into the drivers side gully  about half way up ..the front end came up and we fell over to the passenger side....this is kind of a.secret spot in texas
the above pics are of some trails in southern oklahoma.
some nice steps north of  the red river valley 
i like to call this hill butt pucker hill .it has a 90 degree turn at the top . its in oklahoma also
