Pacific Coastal Mountain icefields and tundra is a tundra ecoregion in Alaska, British Columbia, and Yukon, as defined by the World Wildlife Fund (WWF) ...
Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Because of the susceptibility of ice to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted by glacial channels.
Antarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including South Georgia and the South Sandwich Islands and the Kerguelen Islands. Most of Antarctica is too cold and dry to support vegetation, and most of the continent is covered by ice fields or cold deserts.
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
The Harding Icefield is over 700 square miles (1813 km 2) in its entirety (although, if one were to count its glaciers which descend from the icefield in all directions, the icefield measures in at over 1,100 square miles (2,849 km 2) [1] The icefield spawns up to 40 glaciers of all types.
Wet tundra along with Sitka spruce and Western hemlock forests are mainly found in the Lower bay. In the Upper bay there are tidewater glaciers and from the newly deglaciated land are the post-glacial meadows. In the peaks of Glacier Bay are Alpine tundra, glaciers and ice fields. [29]

This ecoregion is largely separated from the coast by the Pacific coastal mountain icefields and tundra so the climate is continental. Rainfall varies from 200 mm per year on the higher slopes to 400 mm per year in the lower areas. [1]
