Historical significance

The deep, sheltered channel between Cushing and Peaks Islands — one of the historic approaches into Portland Harbor from the eastward. Named for the pale cliff on the Cushing side, it carried fishing schooners, coastal freighters, and, in both world wars, the harbor's anti-submarine net and patrol traffic.

On the ground
  • Strong tidal set through the narrows; look for standing waves on a wind-against-tide.
  • Water depth allows large vessels close inshore, which is why the fort's guns were sited to cover this line.
  • The White Head cliff is the natural range-mark that defines the channel's south edge.
Engineering / Landscape reading

A passage is a piece of infrastructure: its depth chose the shipping, and the shipping chose the fort. Battery Foote, White Head, and this channel are one system — read them together.

Open research questions
  1. 1.Where were the WWII anti-submarine net anchorages, and can any hardware still be traced on either shore?
  2. 2.Which historic charts label this water 'Whitehead' versus 'White Head Passage'?
