The uppie is still there at 3pm.  

After springing my car from the garage (oil-change completed), I decided to go over and look for it.  I arrived just at 3pm and found it immediately in the mown grass/lawn to the left of the path that runs up from the first parking area.  It was about 100 yds in from the path, close to the taller grass and running actively.

Great find, Steve.
