Join Metro naturalist Ashley Conley on a stealthy dusk hike to search for wildlife in the park. Magnificent vistas from atop the mountain will also give us a chance to spot the moon and bright planets in the summer sky. Suitable for ages 8 and older; children must be accompanied by a registered adult. $10 per person. Advance registration required; call Tualatin Hills Park and Recreation District at 503-629-6350.
