Thanks for voting and commenting,

You can see this rock glacier very clearly on GoogleEarth or aerial photos.

Is this a "shen eski"? I do not know its english. Thank you for reading (about my report)

Re: Hi(salam)

I think "Shen eski" is "Talus field" or "scree" where the rock is small. These are likely boulders "Takhte sang".

Nice photo

Hi Nader,
Do you really think there is ice underneath these rocks?

Re: Nice photo

Hi Kamran,

In the past, there has certainly been permanent ice under these rocks but at the present time, I doubt there is any. There are a number of other rock glaciers in the San Juans which probably have no permanent ice at this time. The most famous one is on the 14er Mt. Wilson. Another one on the obscure peak Lone Cone:

Awesome photo!

A very nice rock glacier! I would almost say that this rock glacier is active. It has perfect lobate, rock glacier geomorphology with distinct ridges and furrows and steep frontal slope. Rock glacier research in the San Juans is limited, but I know there are studies being conducted using GPR (ground penetrating radar) to determine if or how much ice is under the talus. Cool stuff!

Re: Awesome photo!

Thank you for commenting Alex,

I am not a geologist and could not tell if this really was a true glacier. Good to know someone else thinks the same.
