Back to the Variolites

Variolites, Olympic Peninsula, WA

I was back on the Elwha River again yesterday, documenting the amazing restoration project underway there after the removal of two old, salmon-proof dams.

(To learn more, go to:  http://en.wikipedia.org/wiki/Elwha_Ecosystem_Restoration)

In the meantime, however, I always had an eye out for one of my favorite rocks - the Variolite, a rare altered basalt associated with the Crescent Formation.

This is not a lapidary stone - it does not take a good polish, but it is rare and unusual enough, that I collect them whenever I see them. In France, they are considered medicinal and just quite possibly spiritual. Who knew?

I'm Back...with a Mystery

Mysterious Rock, Puget Sound

I have not posted for quite sometime, not having had much time - or weather - for rockhounding. But every chance I get to walk on the beaches below my house, I typically find something. In this case, a few weeks ago, I spotted this interesting cobble (about 2" long) and threw it in the tumbler. The polish revealed a fascinating pattern which I can't identify or explain.  Any ideas? A kind of agate?

Rialto Beach Redux

Poppy Jasper, Agate, and....? , Rialto Beach

Last year I made a pilgrimage to Rialto Beach, not far from Forks, Washington (aka "Twilight" Town) to beach comb for orbicular "poppy" jasper. This has been a well-known location for jasper beach cobbles for decades, and every time I'm in the neighborhood, I make a point of stopping by.

I spent a happy hour or two looking for jasper, but also stumbled onto some other nice things as well - some petrified wood, and at least one piece of yellow plume agate. It takes a while to train your eye here: the weather was uncharacteristically dry, so all the beach stones had that pale, scuffed look, making them very hard to identify. I did carry a water spray bottle to test stones -and licked a few - but after a while, I began to see the characteristic smoothness of the harder rocks (mixed in with a lot of rough-surfaced sedimentary rocks, the most common thing on our outer coast).

In the end, I got a nice stash of poppies, and some other things I'll look forward to polishing. Always a great place - and the best part is,  after next winter's storms (profound on this wild coast) there will be a whole new crop of rocks thrown up onto the beach.

Polisher Preview

Cayucos Jasper, CA

Here are two early pieces of the Cayucos Jasper from the Central California coast I found earlier this month (see below) An astonishing diversity of color and pattern, found within just a few yards of the beach. Definitely a place worth going back to.

What the Glacier Dragged In

Unknown Rock, Puget Sound beach

By now you will understand that patrolling the beaches of Puget Sound for unusual stones is one of my favorite spare-time activities. This rock helps explain why. I spent an all-too-short half hour on the beach recently, not finding anything special when this one caught my eye, full of stripes and marbling.  Agate, maybe?  Or something softer like travertine or diatomaceous earth?  I need to test the hardness.

Whatever it is, it is unlike anything I have ever found on the local beaches. Who knows where it's from? My hope, in fact, is that someone somewhere seeing these posted pictures will recognize the rocks from their part of the Northwest. It would be fun to know where the glaciers found them...

Big Stories...in Miniature

Mini-faulted Jasper

I have just finishing polishing some recent finds from beaches along the Puget Sound shoreline that I've gathered over the past few months.  Two of my favorites are here.  The first, above, is one I like because it shows big ideas -- in miniature.  The rock is only 1.5 inches tall, but clearly shows the offset layers caused by movement along a very small, but obvious, fault. This phenomenon is common enough in nature, in scales both micro and macro, but it is not often displayed with such precision in a rock you can hold in your hand.

Petrified Wood

This is also a handsome miniature, an inch-long pebble of petrified wood. Not wildly colorful, but displaying the layers of both bark and what I can only assume is some darker heartwood. I knew I had a beauty when I found this one, but had to wait a month for it to go through the tumbling stages.

Both rocks beg the same question I mused about in a previous post: where could they have come from?  Found on a Seattle beach, both could very likely have been scraped off an outcrop in the BC coast range, or somewhere on Vancouver Island, by the massive glaciers of the Pleistocene. They could have been worn down to pebble size by ten thousand years of surf and tide. I'll probably never know.

The truth is, I just get a kick out of imagining the journey these rocks have taken to my desktop. Go figure.

Petite Poppies

Orbicular or "Poppy" Jasper, Olympic Peninsula, WA

I first stumbled onto this rock as an intriguing pebble on a beach along the shores of Puget Sound, covered with tiny red orbs against a dark matrix. Only later did I learn that they are referred to as Olympic "Poppy" Jasper, from Washington's Olympic Peninsula. Although some sources (like Jackson..see below) describe an outcrop of the stone just west of Lake Crescent, most people find this along the coastal beaches. These were all from a brief walk along Rialto Beach just north of the Quileute River near Forks, WA (Home of the "Twilight" stories)

Most are small and uncommon, but as you train your eyes for them along these cobble beaches, they start to jump out at you. I filled a bucket full of them, although many are badly cracked and pitted and will probably not take a good polish.  These were some of my favorites which have been tumbled for a month or so - yet still show some cracking and pitting - testimony to the brittle nature of the basalt they weathered out of.

Still, they are handsome little stones that I am happy to have found. Someday I may go look for the outcrop, but for now, these will do.
