The Shrinking Glacier.

The Tasman Glacier in this photo has a lake which is 1.4km wide from lateral moraine to lateral moraine at the snout of the glacier, and 4 kms long in front of its snout. According to 2005 mapping, there was an extra 2sq kms of glacier occupying the western half of Tasman Lake.

The large scale imagery of Google Earth (in the panel to the right of this photo), depicts an intermediate stage, with a long glacial peninsula and very large partially detached icebergs in the western section of Tasman Lake.

The meltwater river on the east side of the valley is the Murchison River which discharges meltwater from the Murchison Glacier and Murchison Lake. The Murchison River is sandwiched between the Tasman Glacier with its long lateral moraine extension and the wall of the Tasman Valley.

The Tasman Glacier flows 25 kms from its cirque on Mt Elie De Beaumont to the present snout. In its middle section it is 600M deep.

The Ice Age valley of this glacier extends a further 55kms to the south in which the turquoise Lake Pukaki (30km long) is contained.

Hi David,

You like a yarn, too, I believe. When I am writing some of this information, I have in mind students of geography whom I know get to explore Google Earth and therefore Panoramio. I wish I had these images when I was a student of geomorphology and they would have been used when I was teaching as well.

But then you are one of my encouragers too, for you appreciate the explanations or the stories too.

Kind regards,

Dear Roland,

Thanks for your appreciation. Must admit I am a little surprised because your wonderful and creative images are so delicate and so colourful, yet this landscape is so bold and almost colourless! But yes it is a most interesting environment.

Best wishes,

Great holiday, alright, Jeff. And I had a great time with the camera. Thanks for your appreciation.
