My feet sunk deeply into an area that looked flat; a hollow of sorts, filled with woodland debris.
Stopping, I noticed an interesting collection of rocks tucked up against, and under two long flat stones. This is located about 30 feet from several "turtle" piles of stones, and the face of this arrangement faces west-south-west. Last August, 2015, I discovered that the small white quartz rocks tucked into the stone piles glow bright like lanterns as the setting sun strikes them. I pulled the leaves away. There is about 6 inches of soft leaf debris filling the hollow.
