From this picture, it seems like the car would have been riding "high" as you went off the road. When you reached the bottom of the swail, and hit that rise just before the corn, you would likely have bottomed out and all the important stuff under the car would have hit the ground with significant force. It also appears from the tire marks that you were going at least slightly sideways, not straight. Something is buggered up under there.
