Wow, Lyell is dry this year. Stealing a recent image from artrock23 at SummitPost, I will let him know:



He mentioned some rockfall. His post is somewhere around here:

So, as asked above, is Lyell still a glacier or just an ice field? Or has it yet to be determined which? I was only on Lyell once in the mid-1970s.

Patrick is the stump of a dead tree still a tree?

I think as long as there is some ice left year over year Lyell Glacier still exists, much like a corpse exists till its atoms are released back into the cosmos.

Y'all call that a glacier......Patagonia is having a wet, cold winter and there are big smiles on the glaciers. There is nothing sadder than a dying glacier.

That's a legit question. . . doesn't the technical definition of a glacier require that it moves?

Maybe it's been reclassified as a permanent snowfield?

Jim, do you have any personal observations from your years around Patagonian glaciers? I haven't been there but I've seen reports like this,

Patagonian Glaciers Melting in a Hurry
Ice fields in southern South America are rapidly losing volume and in most cases thinning at even the highest elevations, contributing to sea-level rise at "substantially higher" rates than observed from the 1970s through the 1990s, according to a study published Wednesday.

I don't know if that matters when it comes to classification.

The Patagonia Ice Caps, North and South are the two largest ice caps outside of the polar regions.....1,500 and 5,500 sq. mi. respectively. The last few summers have been hotter and dryer than normal. This winter they are getting a reprieve....quite wet and cold.
I have noticed recession but the glaciers are so large it's hard to determine how much.
When I was on Mt. Kenya in 2005 I compared what I saw with earlier pictures and the rate of recession was astonishing.

A phenomenal documentary if you haven't seen it already
ABOUT THE FILM Chasing Ice is the story of one man’s mission to change the tide of history by gathering undeniable evidence of climate change. Using time-lapse cameras, his videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate. - See more at: http://www.chasingice.com/#sthash.sCHg1E2n.dpuf
