HARD TRUTHS – The Telling Face of Rocks

This gray Keweenawan basalt, whose fifty-foot ramparts flank this stretch of the St. Croix River, is unfathomably old, dating from the Precambrian Eon, somewhere between 500 million and a billion years ago.

It is also the hardest basalt-type rock in America—so hard that boulders of it were used by NASA to test the drills employed on the moon probe.

And yet, these rocks are far from the static, silent objects they seem. There is movement here; those sinuous lines—visible only when the sun shines at just this angle—bring to the moment red-hot lava’s flow when life on earth consisted of little more than algae.

 There are distinctly human 
 utterances here.

These rocks speak volumes of a broad swath of history. Cracks and fissures recount epic battles between ice and stone, heat and cold, forces commanded by gravity. Lichens, some of their species nearly as old as the rocks themselves, bear testament to those ancient algae. For, in the face of otherwise untenable circumstances, only the subsumption of those algae by the lichen has enabled them to survive.

Near the cliff's base, the St. Croix’s natural scums and dissolved tannins have ranked water-level horizons on the rock face—a subtlety captured in just the last nanosecond of geologic time.

And, perhaps most compelling for their flesh-and-blood kinship with the likes of me, there are distinctly human utterances—portrayals of hands, a buffalo head and other symbols—likely made by Dakota or Ojibwe hunters nearly 1,000 years ago.

As I was reading the post, I just could not keep my eyes off the photos of rocks that were so full of creatures, I was tempted to start drawing them! Awesome and beautiful!

Yes, Jean, like finding faces and forms in clouds -- except that the rocks don't keep moving as we watch.

Well, not physically, Jeff, but they do keep on transforming into other things and becoming part of things I have already found, so for me, they do keep moving :) Keep on watching and you will see what I mean.
