The biggest landmark is a radio tower, visible in the upper right.
the sign advises the general public that this lot is under 24 hour video surveillance.
I have a odd attractive to turkey buzzards. Whenever I see them, I will stop and try to photograph them, but the movement of me setting up a camera and sneaking close to them usually spooks them and they fly away. I have no idea what they where doing on top of this little mound, other than playing their version of king of the hill. Still, actually getting setup to photograph without scaring off a naturally timid bird is an accomplishment to me.
