Sunday River is dealing with an unexpected problem with the Spruce Peak Triple. According to a post on the SR website:
"On Sunday evening, July 10, 2016, Sunday River Resort's lift maintenance manager discovered that the foundation of the top terminal of the Spruce Peak Triple chairlift had become detached from the underlying ground. The detachment caused the top terminal to be pulled downhill, which released tension on the haul rope and caused the rope and chairs to lower to the ground between some of the lift's towers."
"Decisions on repairing or replacing the lift have not been made at this point and will depend on several factors, including the results of the investigation. The resort is committed to moving forward as quickly as possible."
The triple was built in 1986. It's not used during the summer. However, normally people are allowed on Spruce Peak for hiking. That peak is closed temporarily during the investigation into the cause of the failure. No one saw the failure when it happened.
