In the event of adverse weather conditions, the Museum will post closing notices on the website and our Facebook page. In general, the Museum will adhere to the following plan:
- The Museum’s Exhibits and Education space in downtown Hillsboro will follow the Hillsboro School District’s closures.
- The Museum’s Research Library and Archives located on the PCC Rock Creek campus must adhere to the decision of PCC authorities. If PCC’s Rock Creek Campus is closed for the day, opens late or closes early due to inclement weather or other factors, the Museum must follow the same schedule. PCC sends unscheduled closure notifications and updates to local television and radio stations, so be sure to check local listings. In addition, a notification recording can be reached at 971-722-6111, or toll free at 1-866-922-1010.
