[Maine-birds] gull ID ?, possible Glaucous, late post

I took photographs back in February of 2009 (which should make me eligible for an award for late posting!) of a gull I am only just now noticing in some photo archives. There is a link below to one of the pics and a link to the gallery which has two shots of the bird. I would like identification help, please. I think the gull is a Glaucous ( ? spelling, 'Glaucous' or Glaucus, Cous Cous or cus cus?). I've never seen one, at least not that I knew what I was looking at. Maybe I did see one and didn' know it? I thank you in advance for your help.
White back and wings, no primary tipping, no dark feathers on it anywhere, both photos areof the same bird on Mount Trashmore
