Repeat Photography

Repeat photography can complement recent investigations based on remote sensing and computer modeling. It can provide a strong tool that visually represents changes. In my first months in Kyrgyzstan I can across photographs of glaciers taken in the At-Bashy Range in the 1960s that were incorporated into the USSR Catalog of Glaciers. Only a few photographs were suitable to document changes in glacial cover because in many of the photographs it was difficult to distinguish between seasonal snow coverage and glacial area. This summer I returned to two locations in the At Bashy Range on several occasions. In both cases even after repeat visits I was unable to return to the exact location of the original photograph. It appears that one of the photographs was possibly taken from aircraft. In addition to the difficulty of relocation efforts, the summer weather was less than ideal. The At- Bashy Range receives the majority of its precipitation in the summer, including snow at high elevations. This past winter was a record snow year and the mountains remained blanketed in seasonal snow for most of the summer.

In my attempts the resulting photographs do not offer much scientific value. They do highlight that retreat is not extreme and offer an interesting glance into the past.


  1. amazing information such blog.thanks for sharing.i am already used glaciers related blog used.thanks for sharing..

  2. Greetings.
    Please take a look at this. I collect photographs of mountain passes and summits in TienShan. There is also a list of expeditions and tourist groups, that had visited the the region.

    Also, if you are interested I have a full set of USSR Catalog of Glaciers for the TienShan and Pamir.
