Back in October I mentioned that we saw some cleaved slate of the Chancellor slate on our way into Floe Lake. Now that I’ve recounted the Floe Lake hike in detail, I feel like I can mention the most geologically interesting things I saw up there. The main thing that caught my eye was a well-developed intersection between equally-expressed bedding and cleavage in the Ottertail limestone, as seen here:

Bonus kink folds in that one! Reminds me of the relationship between fold limbs and cleavage that we saw on the rainy hike up to Floe Lake earlier that same day.

We also saw very similar rocks on the hike up to the Burgess Shale. Here’s one particularly classic example:

It doesn’t get much better than that, folks… Unless you count throwing a fold in for good measure:

This is the typical relationship between bedding and cleavage in the hinge area of a fold:

What about faults? Well, it turns out I saw one of those at Floe Lake, too:

There were some strain markers, too – not sure what exactly these dark nuggets were, but I can recognize a preferred orientation when I see one:
