Photo 1: Lamplugh Glacier. That's not dirt- it's lateral and medial moraine!
Photo 2: the Grand Pacific Glacier is up there somewhere
Photo 3: to give you some idea of the scope of the scenery in Glacier Bay, that black dot on this iceberg is a Stellar sea lion weighing 2000 pounds and measuring 10 feet long!
Photo 4: fog or not, the Margerie Glacier with its 250 foot high face never fails to impress
Photo 5: it even looks cold, doesn't it?
