Hi Tedandgin really very simple; use (4) dirt paths to cover the first river corner (make sure the tool box, remove spaces between fields is ticked) then place another river corner on top slightly in front. Remove dirt paths continue to do this for as many levels you'd like.
The dirt pathes allow you to stack objects that otherwise wud not. Good luck!
Stop by leave me a message and I'll show you if you'd like.
