This is The Columbia Glacier one of the largest tidewater glaciers in Alaska. 🇺🇸 #landscape #travelphotography #glacier #mountain #columbiaglacier #tidewaterglacier #alaska #iceberg #sky #cloudy #cloudysky #naturephotography #nature #ice #icewater #water #waterscape #travel #canonphotography #amateurphotography #princewilliamsound #valdez (at Columbia Glacier)

Harvard Glacier Pressured by its own weight, this active #tidewaterglacier (found at the head of fjords or inlets) is in constant motion. Carrying large rocks and trace #minerals from the earth, glaciers move ahead at speeds of several feet a day, or sudden surges of as much as 300 feet. With an estimated 100,000 glaciers in #Alaska covering three percent of the #landscape and creating most of its #rivers, the connection between #land and #sea is obvious. #Glaciers are rivers of ice that flow from ice packs high in the mountains, where more snow falls than melts. While some glaciers are retreating due to increased melting or a lack of new snow to feed them due to global #climatechange - a few glaciers may actually be benefiting from global warming. Although winter temperatures are rising, so is the amount of #snowfall in areas like Pakistan’s Upper Indus River Basin. Glaciers are growing quickly there. Glaciers in Scandinavia also grew due to increased snowfall in the 1990s but are now retreating very quickly. As ice sheets in Antarctica and Greenland melt, they raise ocean levels. Large additions of fresh water contribute to a changing ocean #ecosystem. Organisms, such as many types of corals, depend on #saltwater for survival. Some corals may not be able to adjust to a more #freshwater habitat. The loss of glacial ice also reduces the amount of fresh #water available for plants and animals that need fresh water to survive. #EndlessBlueAlaska #brentalex
