Ellesmere Gr. Looking west from station 63 K 87 across main canyon to show Pennsylvanian Canyon Fiord red beds. The greenish brown unit at the very top of the section is the Permian Assistance formation.

Ellesmere Gr. Icebergs frozen in sea ice. Canyon Fiord. From station 63 K 88.

Ellesmere Gr. Looking north from station 63 K 90 along fault valley. Tertiary Eureka Sound beds with coal at left, Permo-Pennsylvanian beds to the right.

Ellesmere Det. Howie Kindred, cook, holding NOW cake at Eureka.

Axel Heiberg. Looking north upstream toward station 63 K 101 to show succession of Cretaceous Christopher, Hassel, and Strand formations. In background Cretaceous Kanguk and Tertiary Eureka Sound beds form the high mountains at the skyline.

Axel Heiberg Gr. Looking north from station 62 K 105 with sequence of Cretaceous Strand Fiord volcanics to the right, Kanguk shales in centre and Eureka Sound (Tertiary) to extreme left.

Axel Heiberg Gr. Looking south from station 62 K 106 to gypsum piercement dome and glacier behind it at skyline.

Axel Heiberg Gr. Looking east toward 63 K 121 which is the large conical mound in middle background and which is an outcrop of gabbro, pushed and partly obliterated by debris deposited against it by the glacier. In front, moraine can be seen to lie on previously deposited stratified drift laid down in a moraine lake. This stratified drift forms the flat grass-covered area in front. Later retreat of the glacier extablished a new moraine lake at a lower level and caused the dissection of the older lake deposits on which moraine had been dumped. In the far background is the large gypsum diapic (?).

Axel Heiberg Gr. Near station 63 K 121. Glacio-fluvial lacustrine stratified drift deposits (moraine lake sediments) deformed into a ridge by glacier ice above.

Axel Heiberg Gr. Looking north from station 63 K 177.

Ellesmere Gr. Hard limestone ledge in "Grey beds" of Permian Age at station 63 B 184, 610 foot level.

Ellesmere Gr. Looking south from station 63 K 188 across canyon to show left Palaeozoic limestone of unknown age dipping to the east (left) at 40 degrees. To the right (west)are westward dipping Pennsylvanian Canyon Fiord beds (red) at 15 degrees W.
