A couple of years ago I wrote a post about the Proterozoic Churchill quartzite. At the time, I thought that I had said all I would ever need to say about this beautiful tough metagreywacke. But on July 25th of this year, we visited the sculpted scarps east of Churchill, and the stone was looking so completely photogenic that I ended up with dozens of fresh photographs. This is a small sample.
