Hike on day two on the firth

On Day 2 we got on the river, and before long stopped as a tributary, Muskeg Creek, where our guides caught 4 large Dolly Varden. They would be dinner that evening!
A short distance below the fishing hole, we stopped on river left, and went for a steep hike up to a high ridge which overlooked the river. Our hike ended at some tors – rocky knobs formed by erosion from wind and rain – that indicate the are was never glaciated. Glaciers would have quickly destroyed the tors as they ground over the mountains and valleys.
We had a great view of the river far below, and it was exhilarating to think we had reached the tors that we had so admired from the river an hour or two previously. Along the way we came across some fossils which the guides told us were from coral. The Firth River Valley was once covered by shallow seas, and as a result has deep layers of sedimentary rock.
On the way down, I had magnificent views of a rough-legged hawk that posed for quite some time at the very top of a tall spruce tree. It was quite a sight to finally see the bird that we had heard shrieking for the better part of the morning.
A little further along the river we were back in winter. An expanse of aufeis, ice that forms as water issues from underground springs all winter, framed the river on one side. It was July 16th, but it had not all melted yet.
