Mount Baker forms a prominent landmark visible throughout much of the northern Puget Sound region. Its glaciated slopes rise above Bellingham Bay, as seen here from Mount Constitution on Orcas Island. Lummi Island, another of the San Juan Islands, forms the ridge extending across the center of the photo. The Twin Sisters massif, composed of olivine-rich ultramafic rocks derived from the Earth's mantle, is located immediately SW (right) of Mount Baker.
