I've been working on an audio version of this where you can click on the name and hear a well-know voice pronouncing it. Until then,

(Emphasis on the capitalized sylable)

Coquille River "KO-keel"
Minot's Ledge "MINE-its"
Heceta Head "HECK-it-ah" (some say "Hiss-EE-tah"
Assateague "ASS-ah-teeg"
Scituate "SIT-chew-it"

A couple of others than often get mangled:

Tawas Point "TAH-wass"
Traverse City "TRA-verse" (TRA as in trap)
(Not "tra-VERSE" as in skiing)
Mackinac Point "MACK-in-awe" **
Nauset - Rhymes with faucet
Tybee - TIE-bee
Umpqua River - UMP-kwah
Yacquina - yah-KEEN-ah
West Quoddy - QUAD-dee (not QUO-dee)
Admiralty - say "Admiral" and add "TEA"
Biloxi - bill-OX-ee


For non-Michiganders: The Mack-word is all pronounced the same in:

Mackinac Island
Mackinaw City
Straits of Mackinac
Mackinaw Bridge (or is it Mackinac Bridge?)

But the fort under the bridge is:
Michilimackinac "MISH-ill-ah-MACK-in-ACK"
