If you should dig deep enough, would you be able to get to the?
If you would like to stand directly atop the monolithic country rock of a plate, come to Yellowknife in Canadas Northwest Territories. This city stands atop the naked abyssal granite of the Canadian Shield, the bare bottom of North America. Heres a chart of the Canadian Shield and its geologic provinces: Thanks to the eroding action of multiple Ice Ages, there is nothing between the granite here and the mantle except more granite. Note the exposed granite in this view of town: When you build in the NWT the first step is to scrape any roots and humus off the granite, so youre down to a frostproof footing. Any soil formed in just the last 10,000 years so theres seldom more than a meter of it: Then you kick the occasional boulder out of the way and drill lines of holes in the granite. Drop threaded steel rod in the holes, backfill these with cement or epoxy, then bolt your house directly to the North American Plate. This is called pinning. So as you see, pick the right spot and theres not much digging to do
