I think maybe that Margie has just made the second of two right turns. One of the main street into the park, and the second right turn in the park, to start the circle around the pond in the middle of the park to the gym. The ground to the left of Margie slopes down and I think that is to the pond.
So Chateau, I think she is just past where you have the last red dot in the photo in Post 256 above and then turned right when she got to the circle road around the pond/lake.
