Frank's foot is on a rock we put at the water's edge 30 minutes prior to this photo.  The second rock was at the water's edge four minutes prior.

This is the water's edge, twenty minutes before
we placed the first rock in the top photo.
(The mailboxes are across the road from the rock placement.)

This is the water's edge, eleven minutes before
we placed the first rock in the top photo.

At this point, at the far end of the showing road,
the creek is running upstream, into the bottom.
