Ellesmere Gr. Looking north to show local folding in Tertiary Eureka Sound beds

Ellesmere Gr. Looking north from entrance to canyon upstream from station 63 K 83 to show local folding in Tertiary Eureka Sound beds directly beneath an eastward dipping thrust along which Permian Assistance beds (greyish-green) and Pennsylvanian Canyon Fiord beds (reddish) were thrust over the Eureka Sound. The thrust fault is just above the white knoll at the skyline and can be followed from there to the right at the base of the distinctively red beds below the dark area.

Ellesmere Gr. Looking north to show local folding in Eureka Sound beds

Ellesmere Gr. Looking north from station 63 K 83 to show local folding in Eureka Sound beds in detail and westward dipping greyish-green Permian Assistance beds at skyline and reddish Pennsylvanian Canyon Fiord below the Assistance om thrust contact over the Eureka Sound; notch in skyline is approximate position of thrust fault which dips eastward at about 40 degrees.

Ellesmere Gr. Looking north to show left dark hill of Permian rocks

Ellesmere Gr. Looking north from station 63 K 46 to show left dark hill of Permian rocks against which are faulted light grey sandstones of the Triassic Bjorne formation. The fault possibly dips eastward and may be a normal rather than a reverse fault as shgown on the photo-geologic mosaic.

Ellesmere Gr. Looking north to show dark Permian beds

Ellesmere Gr. Looking north from Station 63 K 48 across valley to show dark Permian beds at left dip to northwest and in fault contact with grey and red Triassic Bjorne beds to the right which dip to the east at 7 degrees near the fault and increase to 60 degrees farther away. The fault is possibly normal and dips to the east (?).

Ellesmere Gr. Looking east to show succession in Permian rocks

Ellesmere Gr. Looking east, down valley, from station 63 K40 to show succession in Permian rocksat left (north) side of valley with grey gypsiferous limestone at base overlain by brown siltstone forming hard cliff and recessive shale unit in between covered by talus derived from the siltstone unit which is overlain by another recessive shale unit. Above this is another hard siltstone, another recessive shale, siltstone, and gypsum (the last two units not shown in the photograph).
