No 7 & No 6. The upper beds examined consisted almost entirely of flaggy dull red sandstones frequently ripple marked. In descending these began to alternate with beds of grey & fawn coloured sandstone, the latter calcareous & white on fresh fracture. Lower in the section while red & red-purple sandstones still continue, whitish & fawn coloured limestones frequently concretionary are intercallated & become thicker & more frequent towards the base. These are then followed by No 6 the amygdaloidal trap, which has here a thickness of at least 50 feet. The thick flaggy limestone was seen underlying the trap in cliffs in neighbouring mountains.

Many of the sedimentary beds are ripple marked. Impressions of sun cracks & rain pittings are not infrequent & at several different levels the surfaces show curious impressions of salt crystals which have since disappeared. The whole indicating a land locked shallow salt lagoon or basin not in communication with the open sea. No fossils or traces of fossils could be found.

At Camp Akamina the rock seen red sandstone somewhat irregular in position.

The dips of beds forming the mountains at any rate in this part of the range do not appear
