Join geologist Nick S on a moderately strenuous hike in Oak Creek Canyon around Potato Knoll. Potato knoll is a slump block that broke off from the Wilson Cliffs thousands of years ago. We will cross the creek, which may be flowing, several times on this hike. We will see petrified wood and a mysterious geological feature. We will identify plants and animals encountered along the trail. Moderately strenuous. Ages 10+. Limited space/reservations required. For more information or to register, please call (702) 515-5367.
