Winter Beaches

Banded Jasper or...?

The beach below my house is primarily sand, esp. during the quiet months of summer, when the surf is at a minimum. But in winter, storming winds and tides throw rocks up onto the beaches, and right now there is a thick layer of pebbles at the tideline. This is perfect for sampling the extraordinary diversity of rocks that characterizes this ancient glacial landscape.

This good-sized cobble attracted my attention today. It was heavy and glass-smooth,  typically a sign of a hard rock like agate or jasper, but with some lovely green and brown banding.  I haven't seen anything like it here before - but that is almost always the case here : rocks deposited on my beach are likely remnants of boulders dropped by glaciers here 10, 000 years ago.

In any case, I popped it into the tumbler - and in a week or so, I'll be able to get a clear look at it. Then it will either go into polishing - or get tossed back onto the beach.

Out of the Tumbler

Beach Cobbles, San Simeon, CA

As I posted back in March, I spent a pretty mind-blowing day collecting on the beaches near San Simeon, California, on my way up the coast. Why was it so great?  Because nearly every rock on the beaches there is of something interesting, whether a brecciated jasper, or an interesting agate, or some things that I don't even know the names for. But whatever they are, they have loads of color and striking patterns and polish beautifully in the tumbler.

They do especially well in the tumbler since they are already well-rounded by the wave action. In fact, I usually skip the first coarse grit step in the polishing process and go directly to the finer 120/220 silicon carbide.

I'm still processing rocks I found months ago, and by the time I'm done, it'll be time to head South again to find some more!

Area 54

Misc. Jasper & Agate, Area 54

Some rockhounding locations are in the guidebooks. Others are not, either by the author's choice, or because they are new locations, found just as others are exhausted by hundreds - if not thousands - of collectors.  This place was not one I'd ever read about, except on a rockhounding club website. I don't know where it got it's name - Area 54 - but it does give the place a sense of mystery: it sounds like there should be aliens or UFO's around.  All I can say is, I didn't see any...

The truth is, I don't know exactly where Area 54 is, or at least where the club trips go. It is somewhere on the road into the Panoche Hills in Fresno County, California. I never found the exact spot they described, but it doesn't matter. You can look anywhere in a 5 mile radius, or anywhere along that road and you will find colorful, sometimes stunning, material. The pieces I've posted here just came out of the tumbler - but I have much more.

My advice?  Next time you're driving south on I-5 in central California, take a short detour and explore this canyon.  You won't be sorry!

FOLLOW-UP NOTE: June 15.  I've finally gotten these stones all the way through the polishing process, and sadly, they don't polish well. Most have a largely matte finish with only a few seams that took a good polish. I might have worried that I had done something wrong in the process (such as contaminating the batch with heavy grit somehow) but there were a few agates from elsewhere in the batch and they took a perfect polish - so I know it's the stones. So if they are jasper, they are a somewhat softer one.

Peacock Rock

Peacock Rock, Puget Sound

The water along the shores of Puget Sound was almost dead calm today, and the sun was shining: both relatively rare events here in Seattle.  It seemed a perfect day to prowl the shoreline looking for rocks, esp. where the rising tide washed over the beach, revealing the stones' true colors and patterns.

Along the shore of Lincoln Park is a favorite spot since the strong currents make for good-sized rocks, mostly free of barnacles and other marine life (I prefer to avoid killing things that live on the rocks, and for that reason avoid low tides).

I walked for half a mile along the beach, and my best find was this multi-colored, thinly layered cobble. I brought it home and cut through it.  It has a handsome patterning and wonderful, subtle colors. I haven't tested it for hardness yet, but I'm hoping its hard enough to take a polish. Either way, it's not like anything I've ever seen here before.

Revealed

I am slowly working through the rocks I collected in southern California last month, including some interesting jaspers from the Central Coast. One of my favorite locations, as I have mentioned before, is the stretch of coast between Cayucos and San Simeon. Some of the most colorful, varied, and spectacular jaspers I have ever found were here, a place I am sure to go back to again and again.

Sometimes, I pick up rocks that show very little on the outside, maybe a little color, or the glassiness  of agate or jasper. I don't remember what I saw with this one. It was yellow overall, with the smooth sheen of jasper, but very little patterning on the surface.

Today I cut through it revealed a wonderful variety of patterns, almost like the "Picture Jaspers" I look for every year in the Owyhee canyons of Eastern Oregon.  These are the two cut ends of the same piece, about the size of my fist.  Wonderful.

Cayucos Jasper

Brecciated Jasper

I'm still poring over the 100 lbs of stones I brought back from California last week (the back of my car riding very low). I had a chance to cut open some of the larger pieces, many of which are of a  brecciated jasper that is common in this part of the Coast range (and several other parts of California).  This one is about 8" inches across and shows a fractured yellow-red jasper with a milky quartz filling.

Not a great picture, I admit, but you get the idea. Not sure how the quartz will polish, but we'll give it a try.  The diversity of the rocks along this coast is truly remarkable.  I suggest walking up Toro Creek near Cayucos, or for the best material, head straight to San Simeon Beach. Wow.

Going Crazy in California

San Simeon Jaspers - Naturally tumbled

I do a lot of beach-walking around the Northwest where I live, and often find intriguing and worthwhile rocks mixed in with a lot of junk. So you can imagine what a kick it is to stumble on to a place where nearly every stone is colorful, and beautifully patterned. I had heard about the brecciated jaspers of San Simeon Creek, near Cambria, California and seen some beautiful examples (see Hans Gamma's mouth-watering collection ) but nothing prepared me for a walk along the surf-line yesterday. It was like walking through a kaleidoscope...  In less than an hour I had filled up two cloth bags, and I could have spent days there, seeking out the perfect specimens.

The location is the small beach area just south of the San Simeon State Park campground. It's only a quick scramble down the slope and out to the beach. Most of the rocks on the beach itself were tumbler-sized. I'm guessing the big specimens must be somewhere up in the Coast Range headwaters of San Simeon Creek and others. But there are also loads of medium-sized rocks (e.g. 1-4 pounds)  up high on the beach, but I didn't have time to carefully go through them. I'll bet there are some winners there.

But for anyone whose idea of a perfect day is to walk along a wild Pacific beach picking up beautiful stones, you would have a hard time finding anything better than San Simeon.

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?

Back from the Dead

Olympic Orbicular "Poppy" Jasper

No, I haven't vanished off the face of the earth. Attentive readers may notice that I haven't posted anything here since October. The fact is, I have been traveling most of that time on non-rock business. Now that I am home again, it is pretty cold and rainy for field trips. So I am spending most of my free time slabbing some of the rocks I collected last summer.

Among these are two good looking samples of Orbicular Jasper, often referred to as "Olympic Poppy Jasper". This kind of rock, associated with basalt deposits around the Olympic Peninsula. They are not particularly hard to find - one of the best locations is Rialto Beach on the Pacific Coast, where you can pick up a few pockets full of jasper pebbles in less than an hour.

These two are from some other locations where I have found slightly larger chunks, some of them slab-worthy.  I will post more as I catch up with cutting.

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.

Hidden Universe

Exterior : Raw and Colorless

Interior : A  Hidden World of Blue

Most of the well-known Owyhee jaspers come out of named sites, with private claims and - typically - heavy equipment. I follow the low-rent strategy, searching for intriguing rocks in canyons and gravel bars.  The challenge is that most of the things I find don't look like much. As I have pointed out several times in previous posts, it often takes a rock saw to show what's hidden inside.

This is a perfect example. The upper picture is of a rock I collected somewhere in the Owyhee area (I didn't keep track). Like many of the jasper fragments I've found it is covered with an orange weathering crust that reveals very little of the rock's internal structure.

The rock saw, however, revealed a blue universe inside the rock that I would never have suspected, full of color and crazy patterns: a real surprise.

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."

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.

Out of the Tumbler

Cayucos Jasper - Revealed

Tumbling stones, esp. hard jaspers and agate, takes patience.... and I am not a patient man. So when a batch's time in the grit is up (and maybe a few hours early) I open it with all the enthusiasm of a kid on Christmas morning.

This batch was one I particularly looked forward to since recent months have generated some exceptional collecting opportunities. A sharp reader will recognize these, for example, as polished Cayucos jasper : I posted some of the rough in this blog on May 2. All are of red jasper, with quartz/agate intrusions. Handsome stuff.

Also included in this batch were some pieces of Idaho Japer-Agate I collected in late June (see my July 4 post). One of them came out of the tumbler today with some lovely patterns and colors.
