Only thing I can suggest is that she turned left from the Bass entrance, missed Kearney and drove down the concrete drainage ditch, about 400 feet, and encountered water coming from a feeder there. Realized her mistake ( sort of! ) and tried to climb out of the ditch onto Kearney.
I’ll buy it!
Oops. No good! The car clearly emerges from the angled feeder and crosses the main roadside drainage conduit. Had to be sitting there, as it’s a “short shoot”.
