10/23 The Rocky Mountain Lake Park Surf Scoter is still present as of 1:30pm today. It was directly north of the playground area in the middle of the lake. Both times I have seen it, it keeps close to a small group of Ruddy Ducks but maintains enough distance to stand out - so my advice for a quick find, is to look in spots where you see small groups of Ruddy Ducks.
I can't take all the credit for finding the Prospect Scoter. I have to share it with Marilyn Rhodes of Evergreen. It was her idea to go up there and take a look.
