Group of Three

The Logger has ended his work for the season.  Today I walked further in to a new area of The Woods, where I found a dried up spring. On the knoll overlooking the spring there were signs of purposely placed rocks: 

Two large boulders, the space between  spanned by two large rocks. 

A row of rocks There are smaller rocks placed in-between, in a row, and one perched at the far end. 

 A single rock placed on a larger boulder, "pointing" in the direction of a trail that leads down to a  spring. The spring is curious. Although it is dry this September, when flush  the water wells up and flows off in two directions, north and south. The small  brooks thus created  end up flowing down  into the lake: one on the north end, the other on the south end.
