The largest glacier, by area, is the Seller Glacier on the Antarctic Peninsula, measuring over 7,000 square kilometers (2,700 square miles). The largest ice crystals that make up a glacier can be as large as apples. However, there are many other ice masses on Earth that are much larger than the largest glacier.
Glaciers - National Snow and Ice Data Center
What is a glacier? A glacier is an accumulation of ice and snow that slowly flows over land. At higher elevations, more snow typically falls than melts, adding to its mass. Eventually, the surplus of built-up ice begins to flow downhill. At lower elevations, there is usually a higher rate of melt or icebergs break off that removes ice mass.

The Taylor Glacier is an Antarctic glacier about 54 kilometers (34 miles) long, flowing from the plateau of Victoria Land into the western end of Taylor Valley. — Credit: Eli Duke/Flickr. Valley commonly originate from mountain glaciers or icefields, these glaciers spill down valleys, looking much like giant tongues.
Why Glaciers Matter - National Snow and Ice Data Center
Glacier melt delivers nutrients into lakes, rivers, and oceans. Those nutrients can drive blooms of phytoplankton—the base of aquatic and marine food chains. Meanwhile, gradual glacier melt sustains stream habitats for plants and animals. So, glaciers often have an indirect impact on wildlife and fisheries.

GLIMS - National Snow and Ice Data Center
The GLIMS Glacier Database enables scientists to map how glaciers have changed over time, allowing them to better understand the impacts these changes will have on water resources, downstream hazards, ecosystem changes, and global sea level rise.The Randolph Glacier Inventory (RGI), which is a global catalog of glacier outlines, is derived from ...
World Glacier Inventory, Version 1 - National Snow and Ice Data …
The World Glacier Inventory (WGI) contains information for over 130,000 glaciers, or about 85% of the total estimated number of glaciers. Inventory parameters include geographic location, area, length, orientation, elevation, and classification. The WGI is based primarily on aerial photographs and maps with most glaciers having one data entry only.

névé - National Snow and Ice Data Center
(1) young, granular snow that has been partially melted, refrozen and compacted; névé that survives a full season is called firn; firn becomes glacial ice; (2) also refers to the accumulation zone of a glacier.
