Nice monochrome.

It's been a while since anyone posted an image of Mother Earth's bones, so maybe I can rekindle some interest.

North Head near Brigus, NL



A geology thesis from some decades ago describes North Head as:

North Head Brigus Area
At North Head (Fig. 2.4), moderately east-dipping basal Cambrian units
nonconforrnably overlie massive volcanic tuffs of the Harbour Main Group (Fig, 2.26). In
basal Cambrian mudstones, siltstones and shales and nodular limestone beds, a mesoscopic
open, s-symmetry syncline formed with slightly convergent axial plane S,. which cross-cuts
the nonconformity with negligible refraction. S2 is weakiy formed in the underlying massive
tuffs and flows of the Harimur Main Group. This syncline is necessarily a post-Cambrian
structure because it deforms Cambrian strata. Its axial planar relationship with S2 suggests the
syncline is an F, fold. In Cambrian shales, slickensides rake 65o to the south on S,-parallel
(moderately east-dipping) shear surfaces, compatible with F, flexural slip. In general, S, forms
at high angles to Cambrian bedding in the Brigus area, making an angle of about 85o (Fig.
3.268). The s-symrnetry of the syncline suggests west-vergence. consistent with the symmetry
of open, macroscopic folds throughout the generally east-dipping panel of
Carnbrian rocks, farther south in the Brigus area (e-g., Fig. 2.1 B).

For my part, I am amazed that the strata are at right angles to each other. Something harsh happened here once with those red rocks!

Such jarring unconformaties commonly record the passage of immense amounts of time, with 100 million or more years years age difference between rocks below and above. A lot can happen in 100 million years considering that humans went from chipping stones to landing on the Moon in 1/10,000 of that interval.

Sounds as if there's a traditional story that explains why those rocks are there. Many, many big boulders in Iceland have names and stories, commonly involving trolls, about how the boulders came to be there, or in some cases, what the boulder really is (= a troll transformed).
