Geo 730: Jan. 4, Day 369: Cool, Clear Water

A final shot of the South Fork Smith River, from the same bridge as yesterday. The rocks look to be the same meta-sediments as we saw back close to 199 in the New Year's photo, likely lightly metamorphosed greywacke. But I didn't look carefully enough to be certain, and these are pretty well out-of-reach.

Geo 730: Jan. 3, Day 368: South Fork Smith River

A bit farther down the road from the previous two shots, there's another bridge that crosses the south fork of the Smith River. We spent a few minutes admiring the incredibly clear water and the views from it before turning around and back to Route 199. The confluence of the North and South Forks is hidden from view here, but it's just beyond the house on the left.

Geo 730: Jan. 2, Day 367: Upstream Along the Smith

Looking from the bridge in yesterday's photo, upstream along the Smith River. This is technically the North Fork, and we're just a hundred yards or so from its confluence with the South Fork. This is right about the point where the coast redwoods peter out, due to both geological and meteorological circumstances. We had driven by countless numbers of them, but we were looking for rocks; spectacular as the redwoods are, neither of us thought to get any photos of them. The rocks appear to be the same metasediments I mentioned in yesterday's post.
