Geo 730: June 4, Day 521: Back in the Tyee

I'm not terribly strong with sedimentary facies recognition, but I do know we're back in the Tyee Formation here. The rhythmic nature of the bedding suggests we're still in deeper turbidites, but just under the tree line, right of center, you can see a darker layer that looks as if it's rich in organic material. There are some coal seams in the the deltaic facies of the the Tyee, though by and large they're not of commercial grade- too thin and too dirty. However, as we turn to the left over the next couple of days, we'll see that the organic-rich nature of the layer above is not unique in this outcrop.
