Mountains that tower over beaches, temperate rainforests, ice fields, tidewater glaciers, and marine depths welcome the visitors that make the trek to visit this off-the-beaten-path destination. These habitats provide homes for mountain goats, moose, shorebirds, salmon, and bears, but the easiest way to get around in this national park is not by foot. Nearly 1200 miles of shoreline curve around inlets and islands. One endangered animal has thrived in this environment, swimming here to feed for the summer before returning to tropical waters near Mexico and Hawaii every winter. This week: the humpback whales of Glacier Bay National Park and Preserve.
