Fort Knox is open for the season. However, the Penobscot Narrows Observatory will not open until the end of May according to Maine DOT.

Maine DOT says a malfunctioning fire suppression system has delayed the season opening for Penobscot Narrows Observatory.

In a press release, Maine DOT says:

A valve on that fire suppression system failed, so we have ordered a replacement, but the part needs to be specially constructed for us.

The hope is to have the Observatory open by Memorial Day Weekend.
