Cannot tell whether or not it's on BM's lot, but the saplings with the pile of rocks is definitely in the Longhorn Ranch vicinity.
The property is flat, hills are off to the northeast across the river. But a good quality zoom lens foreshortens the scene dramatically.
Photos are too many kb to post, but I went to Google Maps and dropped a pin on rd 160 near the development. Then I went to street view at that pin, and turned until I could see the hills.
They match the hills in the sapling photo.
Maybe someone who can reduce photo resolution can do this and show what I mean.
