Glaciers, isostasy, and eustasy in the Fraser Lowland: A new interpretation of late Pleistocene glaciation across the International Boundary

The article presents and summarizes the results of a field research on glacial relief of the Gornaya Shoria mountain region, within the Patyn mountain massif. The Patyn-2017 expedition was organized by the Russian Geographic Society. This region has been very poorly studied in the paleogeographical aspect. The available material can give only an approximate assessment of last glaciation in the Gornaya Shoria mountain region. The massif of Mount Patyn (1630 m) is located in the extreme north-east of the Mountain Shoria on the watershed of the Tashtyk and the Mrassu rivers. At present, the massif is completely devoid of modern glaciation. Early summer snowfields appear on the leeward slopes of the eastern, southern and northern macroslopes. The moraine deposits and the configuration of the relief forms have proved mountain-valley glaciation in the Late Pleistocene. The article also touches upon the issue of the origin of the so-called «megaliths» of the massif of Pustag mountain.

Collapse Structures

A structural depression herein called the "Saskatoon. Low" is apparent on structural maps drawn on the top of the Lea Park Formation–Upper Colorado Group, on the bedrock surface, and on the uppermost till surface. The structure was probably formed by collapse as a result of the removal of salt from the Elk Point Group. The structure presumably comprises numerous individual fault blocks, which are bounded by high-angle step faults. The structure may have started to form during deposition of the Bearpaw Formation. It was well developed, however, at the time of the advent of Pleistocene glaciation and continued to develop until late Pleistocene time. The final collapse is radiocarbon dated at about 12 000 years ago.
