Emmet's Causeway

 is an unmarked location on Mount Desert Island.

Layout
Emmet's Causeway is located in the marshes between Rayburn Point and Echo Lake Lumber. The marshes are not all that notable; they have some dry land, but is mostly submerged under seawater. The most notable aspect about the causeway is its population of mirelurk.
