If you're still looking for the Island, try this: Get a Google, MapQuest, or Yahoo site and query for Dauphin Island, AL.. Then, activate the "satillite" function. You will see a spit of land running from the east end of the island that intercepts the bridge which connects the Island to Alabama main-land. Just to the left (west) of the bridge is the plot of sand that was Fort Powell. On some satilite pictures it may look like a slightly submurged sand bar, because it is at high tide. Although it is much more pronounced now, it's almost submurged geography was one of the main reasons it was abandoned during the battle of Mobile Bay. You may also note that Fort Gaines is at the east end of Dauphin Island. It was believed that this fort could be used as support for Fort Powell (or vice-versa). In the end, the main Union fleet made their run right up the main channel between Fort Gaines and Fort Morgan.
