Test Post

I haven't been able to get any Blogger pages to load for at least the last two days- not even my own blog. Twitter inquiries lead me to believe this is just me, not an issue with Blogger. I'm still seeing posts in RSS, but for those who clip their posts, sending just an intro snippet to their feed, I can't click through to read the rest... or rather, it won't load. I can get to the "create post" page, though, so I'm testing whether I can still post, and if doing so will allow me to get to OTI.

Phoenix Tattoo Pictures: Meanings And Cultural History

The phoenix tattoo is a sign of rebirth. It is the sign of longevity and long-lived prosperity and strength. This symbolism comes from the mythological origins of the phoenix. This mythological bird has been a prominent figure in folklore across many cultures, including Greek, Egyptian and Chinese cultures. It has even been associated with Catholicism, as a symbol of the rebirth of Christ.

The basic myth is that the phoenix lives for up to 1,000 years, then builds its own nest of twigs and ignites in flames. Once the entire nest and firebird burn away, an egg appears and the phoenix is born again. There are many variations on this basic myth, depending on the cultural reference you study.

In the modern world, the phoenix tattoo is among the most sentimental available. It is almost exclusively used to symbolize some type of rebirth or turning point in life. Almost every person who gets some creative form of a phoenix tattoo has a personal story behind the design.

Phoenix Tattoo Pictures:
The tattoo represents something deep that has happened in their life. In this way, no two phoenix tattoos are the same. The actual design of the bird and the colors chosen may be very similar in some cases, but the meaning that the tattoos hold for the person wearing them is almost always different.
In some cases the tattoos will represent a personal transformation while in other cases they may symbolize the belief that someone who has passed away still remains on earth in some form.
Phoenix tattoos can portray colorful birds with lots of beautiful feathers, but they can also be very minimalistic. They can appear as a tribal design in some instances, since they are etched in black and white in a pattern similar to many tribal tattoos. The basic symbolism stands behind them for most people, but great creativity can be used in the design process.

Volcanic Ramblings Part 6: Cascades Slop Over Into Basin and Range

We managed to consistently get started at a decent time each day of the trip, aiming to gather for breakfast at 8:00. Since we had driven about an hour south from the turn-off to Crater Lake, that meant we had to drive an hour north- though I recently realized there IS a more direct, probably significantly shorter route that would have taken us to the SW entrance. But wait'll you see the juicy outcrops we would have missed in that case!

Descending into the Klamath Basin, numerous ~N/S normal faults have opened up some terrific exposures I had never bothered to look at carefully- though the next one (after this) in particular is one I've wistfully watched as I sailed past it more times than I care to count over the decades. But here's the thing: the rock is steep, not particularly competent, so mass wasting into the road is commonly a problem, route 97 is sort of shoehorned in there where it fits, often with little space for pull-outs or break-down lanes... and it's a fast, busy and dangerous road. So opportunities to geologize need to be chosen carefully, with an eye toward safety.

All that said, we did find a few pre-park stops which, though they chewed up and spat out enormous amounts of precious time (the commodity which was in shortest supply for the whole trip), were definitely worth it. For most of the stops on the trip, I tried to remember to take a shot or two of helpful landmarks for anyone else who would like to check the spots out for themselves someday, and so I could more confidently and precisely find them in Flash Earth. The lead photo above is the intersection of Algoma Road with Route 97. We were able to get off the road, park in a pull-out on the south side, get behind the Jersey Barrier (which was very nice to have between ourselves and traffic), and walk a hundred yards or so south to an interesting-looking face we had noticed only moments before.

Here's the first shot of the day ( Note that all the photos in this series will get much larger with a click.):So what are we looking at? Well, that there is an itty-bitty normal fault in poorly sorted, extremely immature volcaniclastic sand (mostly) and silt. The grains looked to be mostly lithic, which is why I describe it as "extremely immature." The offset looks to be about an inch. Here's a view from a different angle:Isn't that purty? I'm quite fond of sed structures, both original and soft deformation, so I keep an eye out for them at stops like this. Not much of note at this one, but enough to convince me this stuff was reworked by water, not just air fall ash. (Obligatory admission: I'm no expert, and I'm always open to correction and/or questioning.)
Backing off from the same spot, with the lovely Dana Hunter for scale, you can get a better sense of the over-all look of the outcrop, and see that the fault is roughly parallel to the cliff face, suggesting this is a subsidiary fault to the much larger one that created this escarpment.Looking a bit farther along, there's a lens of very dark sediment that I took to be a small cut-and-fill structure at the time, but it occurs to me it might be a small channel from near the start of this sedimentation cycle. The next unit down is a brick red layer that looked as if it might be a thick ash-fall unit. Looking south along the face, below, it's quite striking. But at the far end, you can see the same kind of stratification as above the brick red stuff.
Walking south, down-section, more of the same under the bricky stuff...
Turning to look north, yep, it's pretty clear that structurally, we're in basin and range. I would guess (and later 65 mph reconnaissance geology seemed to confirm) that the sorts of rocks and sequences we're seeing here would be up there, too.Below, a block of stretched-vesicle mafic rock that fell from a lava flow above the sediments first shown with the fault...
...and a coarse cobbly layer in the lower section of sediment.
So what can we say about this environment (dons semi-irresponsible speculation helmet)? Well, it's very clearly dominated by a nearby source of volcanic rocks... oh, I didn't show you the view across the highway yet, did I?That'd be Mt. McLoughlin, the southernmost major Cascade peak in Oregon. (I doubt that particular volcano contributed much to this outcrop, though.) But I have to admit, I'm not very confident describing the depositional environment. I'm guessing that we're looking at a braided stream drainage, mostly choked with ash, but with larger channels carrying flows competent enough to move larger boulders. The material is too coarse and poorly sorted to be lacustrine (as the modern-day lake across the road) but I'm not seeing enough in the way of cross bedding and channel features to feel comfortable with what I'd consider a more typical meandering fluvial environment. There are quite a few flows in between thick piles of sediments, so we're not so far from the vents that sufficiently fluid lavas couldn't reach this spot, but they're a fairly small proportion of the pile... less than a quarter for sure, maybe closer to 10-15%.

In terms of age, I really don't know, but I'd bet pre-Pleistocene, because the magnitude of the fault offsets (which post-date the sedimentation) would require at least one or two million years.

One last shot, taken as we crossed the causeway in the lead photo, with a question for Callan Bentley... what was the term for a ramp between two vertically offset blocks? You mentioned it in your posts on structure in the Bishop Tuff. Followup: Callan responds swiftly with the response "relay ramp." That there below is one.

Volcanic Ramblings Part 5: Lotsa Lakes

Looking across Odell Lake to Diamond Peak

I have read several times, in sources that look to be reputable, that the rate of ecological change from the Cascade Crest down into central Oregon is one of the most rapid in the terrestrial (as opposed to marine) world. I'm always suspicious of any claim of unique extremity- who says it's the biggest/tallest/deepest/smallest? But if you watch the change in trees and underbrush from Salt Creek Falls to route 97- the N/S backbone of central Oregon- it really is quite amazing how rapidly and thoroughly the forest changes, not just once, but multiple times. Just west of the crest, I would guesstimate annual precipitation is around 150 inches per year; by the time you get out onto the east side apron, it's closer to 25. The dominant trees grade from enormous DouglasFir, with lush and abundant undergrowth, to Ponderosa Pine, Lodgepole Pine, then sagebrush and juniper scrub.

Geology? Oh, my, yes! The presence of the Cascades creates a barrier to moisture coming in off the Pacific; not only do the mountains catch a large proportion of that moisture, but air descending the eastern slope is, well, descending. It warms adiabatically, with the result that air masses moving into central Oregon are most often capable of holding more moisture than when they went over the pass. Which means they don't drop any more moisture. In this case, the mere presence of all that geology has a profound effect on the types of vegetation that can grow, compete, and reproduce in different parts of the east side.

As an aside, much of central and eastern Oregon is referred to as "High Desert," both colloquially and technically; it bears pointing out that strictly speaking, "deserts" receive 10 inches or less of precipitation per year. My understanding is that the Alvord Desert, on the east side of Steens Mountain, does meet this criterion, but little if any of the rest of Oregon does. More accurately, most of the High Desert is semi-arid grassland, but that just doesn't have the same ring, does it? So High Desert it is.

Not to rain on the parade, though, I think one of central Oregon's best-kept secrets is that there's much more water than I think most people realize... which means, in turn, more vegetation and wildlife than they might guess, as well. Yes, there are stretches that can seem barren (to the unaccustomed eye), and there are lots of glorious "dear gawd, look at all those nekkid rocks" vistas, but there's water, too, and lots of birds.

I had planned to spend the first night in the Chemult area, and had used the old Google machine to check that were indeed hotels in the little town. Oops. Without paying very close attention to where, exactly, said lodgings were, you know, located. There were a couple of ramshackle sorts of huts, members of the Bates Chain of Fine Accommodations, if you catch my drift.

So we put in an extra hour of driving to get to Klamath Falls.

As we rounded Modoc Point, we had a grand view of Upper Klamath Lake... ...and a short distance later, took advantage of a pull-out for a more lingering view.
Don't let all that sparse eastern Oregon water distract you from the fact that it's beginning to look a lot like basin and range. If I were asked to stick a tack onto a US map at the northwestern-most corner of that physiographic province, it's fun to imagine an enormous steel pillar suddenly splashing into existence somewhere out in that puddle.
Our diversion to K-Falls had some downsides and caused some later logistical problems, but also led to some fortuitous stops which we otherwise wouldn't have made. (Dana has already posted on one of those from the next day.) All in all, things worked out well; it was a good first day.

Volcanic Ramblings Part 4: The East Side Apron

The Oregon Cascades are conventionally divided into two N-S sections: the western Cascades, which start as low foothills on the eastern margin of the Willamette Valley, then rise to quite respectable heights before sloping down to the High Cascades. I know that sounds oxymoronic, but it's an accurate description. On route 20 in particular, one crosses two very well-defined passes. You may recall this diagram from my post on Salt Creek Falls:
The Western Cascades is older, ranging from roughly 35 Ma to 5 Ma. The combination of our wet PNW climate, the fragmentary nature of much of the rock, recent glaciation, with the lack of ongoing volcanism means that the Western Cascades have been deeply incised. Indeed, some of the canyons through the area are awesome, and the Western Cascades overall are far more precipitously rugged than the High Cascades- with the exception of some of the big stratovolcanic peaks.

The High Cascades, as implied above, are younger, from about 5 Ma to present. In a few areas, recent glaciation has cut deep canyons well into the High Cascades platform, but overall, the province is a surprisingly gentle swell, punctuated with a relative few peaks that rise another 5000 feet or so above the ~5000-foot pass levels.

The moniker I applied in the title, "the East Side Apron," is entirely my invention, and is not used in broader literature, as far as I know. However it does a good job of expressing my perception of descending eastward out of the mountains toward Central Oregon: a very smooth and steady decline. There are exceptions, of course, but by and large, the east flank is exceptionally gentle. It gets comparatively little precipitation, so erosion is subdued, glaciation was much more moderate than on the west side, and the prevailing winds are from the west, so tephra-rich eruptions regularly cover the landscape with inches to feet of ash and debris, smoothing it out.

One of the more recent large eruptions in Oregon, that of Mount Mazama, is easily recognized in many road cuts in the central part of the state; when coming down from Willamette Pass on route 58, I always point it out to my traveling companions, and if interest warrants, make a stop. The general area where it becomes too obvious to miss is near where the Crescent cut-off takes off to the east near Odell Butte.
Mazama ash and tephra has a distinct creamy-yellow color; its coarseness varies, becoming finer with distance from Crater Lake. Where roads have been cut into and through it, you can see that it has a consistent thickness in a given location, but that unlike a bed of sedimentary rock, it is not horizontal. It follows the shape of the landscape.
In fact, after bringing this odd layer to Dana's attention, it only took a couple of prompts, "Look at the way it's following the landscape," before she let fly with a squee and wildly started scanning for the first safe pull-out she could find.
(lens cap is ~52 mm) As she notes in her description of this stop, the dark cinders are from winter time road gravel, but there's no problem finding as many pieces of pumice as you want to carry away.
I ended up with maybe 7 or 8 of the little buggers; I wanted to stop later to get a couple of head-sized chunks off the roadside near Chemult, but that ended up not happening. Another time.
The best part of this stop? Dana's non-stop squeeing and exclamations.

It's the Only Way to Be Sure

No, I haven't forgotten or given up on OTI, nor (fsm knows) is there any shortage of material I'd like to be writing about. Between frustrations with freaked-out browsers, "unresponsive" plug-ins (yes, flash, I'm looking at you), intermittent wifi, Blogger's new improved, marginally usable compose interface, and the electronic equivalent of Alzheimer's, all combined with an obsessive need to read (or at least skim over) hundreds of news articles, geology and other science bits, glorious photos, humor, political commentaries and miscellaneous other stuff on a daily basis, I just don't have the gumption or patience to get any blogging done.

Put it this way: last spring, I could spent 6-8 hours reading my RSS, keeping up with Twitter, write a post or two for OTI, and pretty easily clean out out 1200 news articles and blog posts. This week I have spent 11-12 hours a day here. I have managed to keep up with Twitter, but only on a couple of days have I managed to finish my RSS items- and I'm not going through any more than in the past.

Like I say, frustrating.

At any rate, the above LOL occurred to me, and I thought it an opportune moment to explain my absence. I don't promise anything, but I do promise I'll try to start posting more. I really want to get back to some geology...

Followup: I fully understand that the above individuals have a substantial dollar value attached to them. They can bill me.

Egyptian Tattoo Pictures: Design Ideas And Popular Symbols

There are so many different Egyptian tattoos in existence today that it would be rather difficult to create a collection of them all. What brings all of these tattoos together is the incorporation of basic themes, people and ideas that represent ancient and modern Egyptian culture. Some of the more common design features incorporated in Egyptian tattoos include:
  • Ankh (cross symbolizing Ancient Egypt)
  • Egyptian Goddesses (each with their own symbolic and mythological meanings)
  • Scarab beetle
  • Tombs
  • Mummies
  • Hieroglyphics
  • Mau (cats)
  • Eye of Horus
There are some very unique designs that can be incorporated into Egyptian tattoos as well. For example, the idea of creatures that are half human and half animal are very popular in the tattoo culture. These tattoo designs have their roots embedded in ancient Egypt.

What is unique about Egyptian tattoo artwork is the culture that they are inspired by. Ancient Egyptians mostly tattooed women. Some of the first tattoos known to man are now being discovered on the bodies of mummies found in Egyptian tombs. These tattoos were often created with dots or slashes in order to create very basic pictures or hieroglyphic words.

Egyptian Tattoo Pictures:
Commonly used for fertility purposes, these tattoos were found more often on women than men.
Today, Egyptian tattoos are common with men as well as women. They are often used for the meaning of hieroglyphic designs, but many get them simply because they like the look of these ancient designs.
Some are simply black and gray while others can be very colorful with elements of gold. Most of the designs are very pleasant and peaceful in appearance, however, there are others that are specifically tailored to be disturbing in nature. Some are even quite romantic, such as those designed after the Egyptian Goddess of Love.
Egyptian tattoos can have a wide variety of meanings. Some may be sentimental, other are based on ancient traditions and beliefs, but most are used for their symbolic meanings or simply for their attractive appearances.
Picture of a wonderfully designed tattoo that combines the Eye of Horus with an Ankh. Plus a tribal inspired pair of wings.

Picture of extensive artwork on the back of a man. A compilation of numerous designs including a large Pharaoh centerpiece.
Picture of an excellent tattoo on the lower back of a woman. A classic Egyptian symbol of a women with extended wings and head wear.
This cute masterpiece is a bit of novelty featuring a mummy-cat with skull, ankh and other elements of the culture.

Star Tattoo Pictures: Ideas And Meanings For Girls And Guys

Star tattoos can be designed to represent something personal or they can be chosen simply for their appearance. Stars are often incorporated into larger tattoos with a lot of fine details, though they are just as often presented independently. There are many different types of stars that can be chosen from and some artists will design their own stars with different colors, designs and shapes.

Two of the most popular star tattoos are the shooting star and the nautical star. Both of these images have a rich history in the tattoo world and can stand for different things. They are also very diverse in the way they are presented in tattoo form.

Shooting stars by nature shoot through the sky with brilliant beauty but then quickly fizzle out to nothing. Tattoos with this design are often used to symbolize periods of life that were short lived, but which will always be remembered. It is common to find names etched into the centers of these stars or somewhere in the stream of the rising star.

Nautical stars are tied to servicemen and women of the U.S. Navy and Marines Corps. Yet, they are used heavily by people who associate strongly with the sea today. These star tattoos have a very clear design with a particular pattern of shading or coloring.

Star Tattoo Pictures:
Both of these types of star tattoos can be shown as individual stars or as groups of stars. They can also be incorporated into other tattoo designs. For instance, nautical stars will often appear in tattoos reflecting ships, water, skeletons, roses and cherries, among other designs.
Star tattoos are extremely popular in Hollywood. You could compile a long list of celebrities that feature some type of star on their bodies, including Drew Barrymore and Gisele Bündchen. This is probably because celebrities think of themselves as stars, though some select star images for personal reasons just like everyone else in the world.
Picture of a pair of swallow birds perched on small branches while holding cherries with a smattering of small and large stars covering the back.
Picture of a lovely flower and a stream stars located on the hip and torso area of a woman.
Photo of a bright and colorful design featuring several musical notes mixed with numerous stars of various shapes and sizes.
Picture of many solid stars in black ink located on the stomach of a woman. The three larger designs all possess a unique shading and stencil effect.
And finally we see five solid black and bold designs gracing the top portion of a right foot.
