Structures in the icePasterze is one of the glaciers where the earliest studies of foliation were studied and described. |
![Structures in the ice Structures in the ice](icons-structures/hufeisenfall.jpg) The great icefall of Pasterze generates the ice structures presented on this page (overview from Franz Josefs-Höhe). | ![Structures in the ice Structures in the ice](icons-structures/ogiven_bildung.jpg) A closer view of the glacier just below the icefalls shows faint ogives (lower left). | ![Structures in the ice Structures in the ice](icons-structures/ogiven.jpg) Zooming in even more, ogives and folding caused by longitudinal compression of the ice become evident. | ![Structures in the ice Structures in the ice](icons-structures/folding_snowpatch.jpg) The strongest zoom shows intensively folded ice near the true left margin of the glacier. |
![Structures in the ice Structures in the ice](icons-structures/folding_blocks.jpg) Telephoto view of strongly folded ice at the true left margin of the glacier. | ![Structures in the ice Structures in the ice](icons-structures/folding_ogives.jpg) Telephoto view of ogives and folding near the centerline of the glacier. | ![Structures in the ice Structures in the ice](icons-structures/meltwater_channels.jpg) Fisheye photo taken when standing on the glacier, in the are below the icefall. Meltwater streams exploit structures within the ice. | ![Structures in the ice Structures in the ice](icons-structures/pasterze_fold_1.jpg) Anticlinal folding becomes evident due to uneven ablation of different types of glacier ice. |
![Structures in the ice Structures in the ice](icons-structures/pasterze_fold_2.jpg) Anticlinal (far left) and synclinal folding (right foreground). | ![Structures in the ice Structures in the ice](icons-structures/eis_stauchung.jpg) Ice of a tributary glacier descending via a small icefall is strongly compressed in the longitudinal direction, also causing folding. | ![Structures in the ice Structures in the ice](icons-structures/pasterze_folding_longitudinal.jpg) Fault showing lateral displacement to the right and bending of longitudinal foliation. | ![Structures in the ice Structures in the ice](icons-structures/pasterze_loch.jpg) A deeply incised meltwater channel exposes foliation structures in the ice. |
All photos where taken on 6th and 7th August 2009 by Jürg Alean. |
