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?

Small Treasures

Jasper Patterns, Owyhee country

OK, OK, I've been pushing the Owyhee jasper a lot lately on this blog. The truth is, that's about the only rockhounding I've had time for lately, and most of it has been just going through the pile of material I brought back from my last trip. I've been cutting a lot of pieces on my Lortone 10" saw, with mixed results as I've mentioned before. Sometimes there is great stuff, and sometimes there is just another wasted hour of saw-time.

These never saw the saw: they were fragments of a rock I broke open to see what it was made of. I knew right away it was something special, but it was not big enough to slab. So I opted to toss them in the tumbler - and both came out smooth and lovely, with handsome patterns on all sides. (Both have a lot of blue on at least one face.)

Anyhow, nice stuff...of unknown provenance. I suppose I could keep better records when I am in the field, i.e. get a GPS plot of every piece I pick up - but hey. I'd rather be looking for rocks than bending over my laptop. Anytime.

I will be traveling for the next few weeks, so probably not posting. Maybe I'll bring something interesting home.

First Creek Jasper

Jasper, First Creek

There is a well-known location for agate and geodes in First Creek canyon, on the Blewitt Pass highway north of Ellensburg.  (see:  http://happyrockhound.blogspot.com/2011/05/first-creek.html)  I have passed by there several times on my way other places, but have never really explored the upper parts of the watershed. However, earlier this year, I did poke around the lower creek a bit, on the assumption that rocks wash downhill...

One of my finds was a weathered brownish lump that revealed just a hint of patterning inside. On a hunch, I tossed it in the bag and brought it home for the polisher.  This is what it looks like now,  after the final polish, a rather graceful stone of brown, orange and a streak of blue-gray. In other words, quite unlike anything I have ever seen come out of First Creek.

Maybe it's a glacial remnant from somewhere else, or part of a filled cavity somewhere in the local basalt. Either way, it's my "rock of the day."

Unexpected Fossils

Fossil leaves/needles, Owyhee country

Sometimes, when I am in serious rock-collecting mode, I am picking things up on a whim - a flash of color or pattern might catch my eye. But I generally don't spend a lot of time inspecting each one. Often they just go into the bag for future study. Maybe this is why my car rides so slow when I come home from a trip!

As I have mentioned in previous posts, I was recently collecting in one of my favorite areas, the Owyhee mountains on eastern Oregon. I have been sorting through the specimens I collated, tossing out some, and polishing those that are worth the effort, especially picture jaspers. (see earlier blog post)

But this one was a surprise, different from anything else I saw, and with a pale purple that caught my eye. I tossed it in the bag and only took a closer look today. Breaking off a piece revealed an inner layer  crammed with leaf fossils. I haven't identified them, but they look like conifer needles, twigs etc. strewn throughout a single layer in what I am guessing is rhyolite tuff. A nice surprise!

Christmas Morning

Owyhee Jaspers revealed

One great advantage of a rock saw is that you can non-destructively look inside a weathered rock whose outward appearance is almost nothing like its inside. I have just come home from eastern Oregon with huge amounts of jasper from the Owyhee country, but very rarely are the patterns and colors obvious through the weathered crust. Some things that look intriguing on the surface are dull inside. However, the reverse is also true - some real treasures have no outward sign of what's inside until you break them open - or use a saw.

In the past I had nothing more than a rock hammer to see what was inside - but jasper is really just a natural glass, and often cleaves and shatters in unexpected, and unwanted, ways. I hate to think about the number of really fine rocks that have disintegrated under my hammer! A lot of weathered picture jaspers, for example, are riddled with cracks, which is precisely why there are such great patterns in the first place. These clearly have no business being hammered...

The saw, meanwhile, provides a window into the rock, without risking damage. Now, all I have to do is choose the pieces that look good - like the three above, which I just cut yesterday from very humble fist-sized pieces. The best  go into the tumbler to smooth out the rest of the stone.

After this last trip, I've got many, many more waiting to be opened up.  Can't wait.

Crazy Mixed-up Jasper

Owyhee Jasper

For years now, I have been in love with the stunning variety of colors and patterns that jasper can take on. And when you are talking about colorful jasper, it's hard to beat those from the amazing Owyhee Mountains of Eastern Oregon. Yes, I find plenty of interesting things around my home near Puget Sound, but several times a year I make the 9-hour drive out to this, my favorite rock location on Earth.

I spent just a few days there this time, collecting in the Succor Creek drainage and along Leslie Gulch. To be honest, I stuck to some pretty familiar, accessible locations. Frankly, if it hadn't been 95 degrees I might have explored further away from the roads, but I promised my wife I wouldn't do anything too crazy. What's truly amazing is how much there still is, within easy reach.

As I may have mentioned before, my inspiration has been Hans Gamma's breathtaking collection of Owyhee area jaspers both on his website and his book.   He knows some really hidden corners of these mountains that some day I will get to. But for now, I have several hundred pounds of jasper to sort, cut and polish.  Stay tuned for results.

Skokomish Obsession

Orbicular Jasper, Skokomish River

Somebody stop me. I have made two trips now to the Skokomish River looking for orbicular jasper. Today was a beauty, sunny and warm, and the river was running gin clear (see photo below). Good conditions for looking for jasper. As before, there are loads of interesting jaspers on this river, but very few have well-defined red orbs, so you spend a lot of time picking up stones, and then discarding them.

This one was high and dry on the gravel bar, and jumped out because of its vivid color.

I found others in the water, as in the photo below. The only trouble is...you can't see the water. Believe it or not, these rocks are under a smooth sheet of water, e.g. just about perfect for scanning for rocks. And surrounded by drably colored rocks, the red jasper almost jumps out at you!

The Skokomish Runs clear in August

Hands and Knees Jasper

Cherry Creek Red Jasper

No, I haven't discovered a new type of jasper - the title of this post refers to how I spent most of my day today...on my hands and knees (in the water)

 I decided to go out this morning to Cherry Creek, near Duvall, Washington, to look for bits of high-quality red jasper. I had been there two years ago, and all I can say is, plants grow fast here in the Northwest. This small creek was walkable last time I was there - this time I was literally crawling up the creek, under an almost solid thicket of shrubs and small trees.

The only upsides to this technique are 1) I was a LOT closer to the stream gravel, so I could see some of the bits of jasper which tend to be small. and 2) I suspect I was the only person willing to put up with this - there was a pretty good scattering of jasper once I left the "easy" part of the creek.

This location has been well-known for decades, and a lot of mineral clubs have field trips to the site,

(see: http://home.comcast.net/~wams1939/trips/cherry.htm)

so it's not exactly easy pickings anywhere. But it is close to home, and there is always the promise of a really nice bright piece of jasper. Not sure I found it today, but I got a nice bag full in a couple of hours.
Having said that, I probably won't be back without a machete...

Rock Saw Discoveries

Over the past year or two, I have been collecting rocks from a variety of sources - from the deserts of Idaho, to the Pacific coast, to the beach just below my house. Most end up being polished in my two Lortone rock tumblers with terrific results.

However, until this week, I was never able to cut into the middle of larger pieces: I needed a rock saw. Well, after hemming and hawing, I finally bought one last week on Craig's List. It is an antique Lortone LS-10, well-used, but still working - and I have been cutting ever since. I had a large box of large rough under my workbench that I had been waiting to cut into, and now I am finally getting to see what is inside these pieces.

Examples above : a pale jasper from western Idaho, and a piece of Succor Creek Jasper from the Owyhee country.

Cutting a rock is like Christmas: you never know what you're going to get. Sometimes you find great stuff - sometimes you get nothing. Still, it's another tool in the arsenal. Next, I'll have to start polishing the slabs.

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.

Gravel Galore, Rialto Beach

The Tip of the Iceberg

Succor Jaspers - polished

A nice batch of Succor Creek Jasper came out of the tumblers today, which shows you some of the diversity possible in this area, and the quality of the polish that the rock takes. Yes, there are a few nicks and scratches from the tumbling process; hopefully these will come out by the end, but a few still remain (usually the result of having some over-size rocks mixed in - these tend to break chips out of one another.)

The obvious question its "why not slab this stuff and enjoy the patterns in 2 dimensions?"  Well, I might if I had a saw, but I also get some pleasure out of the random-ness of this process, which seems somehow more "natural." Probably just a case of rationalizing my own equipment deficiency - but that's how it goes. I tend to scavenge for small tumbler pieces, preferring them to large hard-rock excavation, the kind that produces good slabs.  Maybe that will change one of these days.

Skokomish Jasper

Skokomish River Gravel Bars

I set out this morning on the trail of poppy/orbicular jasper on the South fork of the Skokomish River.  It is only about a two-hour drive for me, and an easy day out. I used to go salmon fishing on the Skoko many years ago, and not been back in several decades. I was tempted this time by posts made by a fellow NW Rockhound Charley Price on his blog : Compass Mentus.  Charley recently posted about finding orbicular jasper on the Skoko, so I thought I would give it a try.

I hiked in about 1.5 miles on the Skokomish River Trail which begins at Brown Creek Campground, some 16 miles upriver (mostly paved).  It is a steep up and down (and VERY steep at the end with whatever you have collected on your back!) but eventually you get access to the river, which runs very clear, and has lots of interesting rock to look through. I kept my eye out for really bright orange-red rocks which is usually a tip-off for jasper.

Orbicular Jasper (on left) and another type

I came out with a backpack of about 35-40 pounds - most of it without clear orbs, but a few nice pieces.
I would say it's definitely worth another trip sometime and exploring further upstream.  However, I have to say that the cougar warning sign at the trailhead had me looking over my shoulder!  ("Never Hike Alone" it says...)

Another thing Charley tipped me off to was the presence of some truly weird pieces of mudstone, eroding out of a cliff at the water's edge. For reasons that are not entirely clear to me, these pieces are in some pretty wacky shapes, but are hard enough to make it home intact.  Something for the grandchildren at the very least...

Mudstone animal : Platypus?

All in all, a nice day out in bright overcast 75 degree weather. Pretty much perfect!

Succor Creek Wood

Petrified Wood, Succor Creek OR

Haven't been out into the field lately, but I am still working on the material I collected at Succor Creek in early June. Although most is high-quality jasper, including some with nice "picture" designs, I also found a fair amount of petrified wood.  Here are just a few of the pieces I gathered along the creek.  I'm sure there's a lot more out there...

Hope to make it back to the area later this summer. In the meantime, I will be exploring some locations closer to home. Stay tuned.

More Succor Creek Jasper

Succor Creek Picture Jasper

I've been home from Owyhee country for two weeks, and am starting to get some of this material polished. These are probably not the most dramatic picture jasper pieces I've ever seen, but they have a wonderful variety of color and pattern.  I am also very pleased with some of the petrified wood that came from the trip.

I have much, much more to go through - and some will be reserved for the day - one day - when I actually buy a saw, and cut some slabs. I have hesitated to invest in a saw up until now because 1) they are expensive and 2) because I have no interest in making jewelry. I really only do this for the pleasure of discovery and the beauty of what emerges after simple tumbling. In every hobby there is the inevitable choice - do I keep this casual, or invest in more equipment with some larger goal.  Frankly, I'm not there yet.  But as I find larger, better pieces, I will be tempted to cut slabs from them - if only to enjoy the larger canvas for the art of the stone.

Surprises

By now, you will realize that my idea of heaven is to wander along local beaches picking up interesting stones and trying to piece together the stories behind them. I often fill a bag within an hour or so, and only weeks, if not months, later get to polishing them. So I can maybe be forgiven for not exactly remembering where I found this one, which emerged from the tumbler today. It is of a free-form yellow jasper together with what looks like a pinkish agate. Pink agate?  Never heard of it before - and as always, I have no idea where this rock originated, thousands of years before it landed on the beach where I found it. Yes, it would be nice to know: I'm guessing there are more like it...

Succor Success

Succor Creek Jasper

I'm home and have had a chance to clean up some of my rocks from Succor Creek.  Wow!  I am delighted to have hundreds of pieces of every size and shape. Some I will save for slicing, but I have loads of tumbler material of very high-quality - much better than I got last year.  I am particularly happy to get so much of the Succor Blue Jasper, which I think it stunning.
I haven't shown any here, but I also got some very nice petrified wood fragments - including one very dramatic chunk of swirling black wood. (I'll try and post it later)
I also did some poking around some other areas in SW Idaho, and found a small creek in the foothills around Boise with some stunning football-sized chunks of Yellow/Orange Jasper.  It looks like it may have cracking problems, but I will have to cut into it to see how it holds together. But it has the potential to be stunning.  Two sample pieces below.

Idaho Jasper

All in all, a VERY successful trip. But as I mentioned in my earlier post, next time I go back, I really have to explore some more. There must be vast quantities of hi-grade jasper in those mountains...

Right off the Beach

Many of the stones I gather are truly "diamonds in the rough," rocks whose pattern and color you can really only guess at until the tumbler has scoured off the weathering crust, the scars, cracks and staining.  Then there are the stones that appear, at first glance, as if they have already been polished and shaped.
That was the case with this one, a reddish-purple stone that looks like a translucent jasper/agate. It has a glassy character, but also a granular texture, along with random black dots and faint stripes.

If you have any ideas what this might be, I'd love to know. In the meantime, it is simply a lovely stone of an unusual color.

Discovering Ancient Forests

Petrified Wood, Puget Sound

Every time I open up the tumbler at the end of a polishing cycle, it's like Christmas all over again. Some stones, especially soft sedimentary rocks, never take a polish - but those that do can reveal some stunning patterns and colors. And one thing that I am always happy to see is Petrified Wood. These came out of my tumbler just this morning, pieces of wood I have found along the beaches of Puget Sound over the last few months.

On the beach, they are not always easy to recognize. Although they take a beautiful polish after the fact, they show none of this luster and translucency after they've been tumbled in the surf for a few thousand years. But somehow these caught my eye anyhow - and I'm glad they did.

I have begun to see recurring styles of wood: jet black with tan bark remnants, yellow/orange with strong ring patterns etc.  To me, this suggests a couple of specific (but unknown to me) source locations in the Puget Sound basin.  Logic dictates that the more abundant a certain rock type is, the closer the source. (Or maybe it means that some distant sources are simply more productive)

Wherever the source, they are beautiful.

Patterned Quartzite (?) and Petrified Wood, Olympic Peninsula

I set out this morning to look for a source of variolites, the polka-dotted rock I have posted about in the past, and which probably originates in the basalts of the Crescent Formation on the Olympic Peninsula. I tracked down a couple possible source areas - and found no evidence of variolites. In fact, I didn't find a single one, which is unusual - I have found them in a variety of locations along the Olympic coast. This would suggest that the source is somewhere further west than where I was looking today.  So another expedition is clearly required...

However, I did get some time to poke around the coast near Sequim, where I found - among many other things - these two beach cobbles: a stained quartzite (or Jasper?) and a handsome piece of petrified wood. Not bad for a quick beach walk.

Missed Opportunity

Owyhee Picture Jasper

I had big plans to head back to the Owyhee country in eastern Oregon this fall to search for more jasper. I had been there in the spring, but high water made access to some of the best collecting sites too difficult, so I promised myself to make an autumn trip.  Well, the rains have started, and autumn has arrived faster than I expected - and my schedule is now too full to allow a minimum three-day trip to the desert. I guess it will have to wait until next year.

These three fragments, polished chips from a piece I collected last spring, will remind me of what I'm missing: one of the greatest collecting locations in the Northwest.
