There's some rock visible in Bing here. Its not unreasonable to assume that the blurry rock seen in imagery is the same feature represented by the existing island (way/232976567), so I tried to improve the island with Bing. However you are right that I should not have edited this island with only Bing. Thanks for the call-out, I will avoid editing these islands with blurry imagery in the future. I am finding these overly angular islands using a MapRoulette challenge.

Hi Dave,
Thanks for catching that, I did not mean to. I've added the pier back: way/483803328
Thanks again,
Ashley
