We came across the above gull at the Keegan Landfill last week, and took it to be an Iceland Gull.
We believe the bird was seen again on Saturday, since a birding group pointed out what they ID'd as an Iceland Gull to Doug Morel, who took the photo below.
Chris Takacs posted the landfill photo on his blog, which elicited an interesting comment from a knowledgeable birder, who suspects the bird is actually a leucistic Herring Gull. (More on leucistic birds here.)
