large white gull, glaucous vs gl-winged, Cherry Creek SP/Arapahoe

[Karl Stecher Jr.]

Late yesterday afternoon I saw a large white gull, too far out for my ID, at Cherry Creek State Park.  I lean toward glaucous (brief view from one wheeling, or perhaps my wish), having seen many glaucous in Massachusetts and being swamped with glaucous-winged in Seattle.  Will look again today.

The bird was seen from the marina area, out and slightly to the left of the long boardwalk.
