If you really wish to be completely pedantic, you can cut it back to where it was originally, up to the water pond for live stock. Up to here I can confirm that it is clearly visible and flat, can't be mistaken. The rest I just saw on the aerial photos from BEV.
Yes, it does seem a soft soil. I just crossed it, did not really walk on it for longer distance. It seems like one of those tracks for getting the hay out of the pastures.
