As for the obstacle, its a bit embarrasing, but this is what caused all the carnage.... And I was driving slow, very little skinny pedal...
The photo I found here doesn't do it justice. The obstacle changes daily with the rains, and usually is about 4 to 5 feet tall... It's still embarassing to break that badly on something so small. I'm going back with my comanche when I'm ready....
This is from the night it happened...much more washed out.
