Nestled in the woods away from the Quaker Conference Center in the mountains outside of Ben Lomond, a newly constructed labyrinth, made of simple gravel and river rock, opens in a clearing.

The labyrinth allows prayerful meditation around a predestined course, with one way in and out. Members Traci and Walter Hjelt-Sullivan are on the labyrinth with Davis.
