Maps of Glacier Recession, Muir Inlet
	Types of Glaciers	These maps, both compiled by Bill Fields, show retreat of the Muir Glacier from 1880 until the 1980s. The record has subsequently been extended by satellite measurements. Even though the Muir has been shrinking for over 200 years, it is not a good indication that the Earth's climate is warming. A tidewater glacier, it's rate of growth or recession is determined by the calving of icerbergs at the terminus. A nearby tidewater glacier, the Great Pacific, has been growing rapidly.
