Due to safety considerations, the exhibit halls within the Wickiup Hill Learning Center will be closed to the public Monday and Tuesday, April 24 and 25 as part of an LED lighting upgrade. There will be limited access to the building during normal business hours of 8 a.m. -4 p.m. Restrooms located near the front entrance will still be available for use. The public is encouraged to visit Wickiup's outdoor nature playscape and numerous trails as Linn County Conservation completes this indoor energy efficiency project.
