You're looking pretty well preserved. I worked on Gabriola many years ago, first time was when Davy Barrett had a scheme to build a main ferry terminal on Sears Id. at the south end of Gabriola connecting with 2 bridges one to Mudge Id. and another to Duke Point near Harmac. About 5 minutes after we completed the survey the plan was scrapped.-

That rock almost looks volcanic.

To be honest that photo is about eight years old. I probably feel older than I look in that photo..

I recall years ago right at the north end of Gabriola Island seeing a bunch of millstones just more or less abandoned! What the history of them was I have no clue!

Hornby has similar formations. I was once told that it is volcanic mud that brought up harder rocks. They eventually fall out which makes the holes.

I was told once that a lot of the big millstones were sent to China.. Here is a picture that gives a hint as to how they were made:



They were core-drilled.......I always thought they were turned on some kind of lathe.

Yep. Conglomerate is the term; a mix of hard and softer rock. Erosive forces like water and wind wears away the softer stuff faster and destabilizes the harder stuff.

Looks a bit like fossilized ant hills which turn up at my place once in a while.

You get many visits from these "fossilized anthills"?

The fossils are sometimes turned up by the excavator after the blasting Lester.

You have a excavator that blasts things? Interesting.

Not to be a smart *** but its not a conglomerate..... In my opinion if it was we would still see pebbles and rocks larger than the matrix still sticking out of the outcrop... Neither is it igneous because light igneous rocks dont weather smoothly like what we see in the picture... Im thinking carbonate

It is limestone. Before there was the back island arc of van island it was warm shallow sea just before the Jurassic Sevier Orogenesis 140Ma - 50Ma of western rockies and such westward to the cascades during the Laramide orogeny period 40Ma - 70Ma.

Sauce made from pluton ground dinoflagellates from the georgia strait sediment horizons on the cabonate to clastic nonconformity?

So. Was Vancouver Island once a part of the mainland? Will we find those holey rock formations on the west coast of the mainland?

The island rose up from the dead.

subduction induced process called a back arc

No way !!!

It's "calcified libitinous moribundinated hardened magmanite.

Great Photo! The piece of crust that included Vancouver Island is known as Wrangellia. Through plate tectonics , Volcanism, glaciation it is one old Rock Vancouver Island. Chris Yorath's Geology of Southern Vancouver Island is a good little field guide a lot of photos . There are also Volcanoes that can be identified on the island trek as well. Local towns people that are in the smaller community's are the best coffee shop talk I have found for information gathering on trails

Dunno. I can tell you that eventually Cali will be right beside Alaska and VanIsle might be over beside China in a few million years.

Looks like the sponge you find underneath the chocolate(not sure the name of that particular treat). The rocks, that is, not you. LOL! Neat picture, Juan.
