Eons of Ice
March 9, 2016
This is a close up of the striations in the ice contained in a very small portion of the Margerie Glacier in Glacier Bay National Park. Parts of the ice in the Margarie were pale sky blue, others almost white and there were sections that had the dark streaks through them that are called moraines.
Best viewed in larger sizes.
According to wikipedia: "A moraine is any glacially formed accumulation of unconsolidated glacial debris (soil and rock) that occurs in currently glaciated and formerly glaciated regions on Earth (i.e. a past glacial maximum), through geomorphological processes. Moraines are formed from debris previously carried along by a glacier and normally consist of somewhat rounded particles ranging in size from large boulders to minute glacial flour. Lateral moraines were formed at the side of the ice flow and terminal moraines at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines, till-covered areas with irregular topography, and medial moraines which formed where two glaciers met."
Notice also the Seagull in the shot. There were lots of Seagulls around while we were anchored in Glacier Bay.
"Future generations are not going to ask us what political party were you in. They are going to ask what did you do about it, when you knew the glaciers were melting." ~ Martin Sheen
Thank you for your comments and critiques.
Have a beautiful day today my friends.
