Each Sunday we present a notable item from our archives. This EPOD was originally published March 27, 2003.
This image taken along the Bright Angel Trail in the Grand Canyon clearly shows cross bedding in the Coconino Sandstone layer exposed by the canyon. The tan colored Coconino Sandstone is one of the most dominant features of the Grand Canyon. This erosion resistant layer forms a spectacular cliff of 300-500 feet (90–150 meters) not far below the Canyon’s rim. Dating to approximately 260 million years ago, the Coconino is composed of nearly pure quartz sand. The cross-bedded features indicate that the Coconino Sandstone is basically petrified sand dunes. Formed through aeolian (wind) deposition, sand dunes slowly migrate downwind. Sand grains are carried up the windward side of the dune then deposited near the peak. Angled layers are formed as the newly deposited sand avalanches down the leeward side of the dune. The strata of the Coconino Sandstone show some of the most distinct examples of cross-bedding on the planet.

I was first amused and then subsequently puzzled by the copyright notice under the picture. This is, after all, a publicity still created with the intention that it would be copied and published by other people.
At any rate, I'm assuming that at this point in the game I'm a) too small a fry a b) people distributing publicity images on the Internet is too common a thing for the BBC to come after me, but I suppose we shall see.
Today, and every Saturday Earth Science Picture of the Day invites you to rediscover favorites from the past. Saturday posts feature an EPOD that was chosen by viewers like you in our monthly Viewers' Choice polls. Join us as we look back at these intriguing and captivating images.
The photo above shows a jaunty rainbow stretching over a cornfield near Piberbach, Austria. My shadow clearly shows the direction of the antisolar point -- the only direction where rainbows can be observed. Note that the fainter secondary bow is also visible (at left). This bow is caused by two internal reflection of sunlight in raindrops. Since some light is lost with each additional reflection, secondary bows are only 43 percent as bright as the primary bow. Photo taken on July 21, 2011.
Photo Details: Canon EOS 550D camera; ISO 200; Peleng 8mm fisheye lens; f/8; aperture mode, corrected by -1 stop, resulting in 1/60 sec. exposure.
the important proportions bits:
2 medium onions
6 cloves of garlic (pressure-cooked garlic is almost imperceptible -- next time i'll put the whole head in)
slices of raw ginger
2 cups sliced crimini mushrooms
2 cups diced celery and carrot
2 cups medium-grain brown rice (nishiki brand)
3 cups liquid (i used vegetable broth)
2 lbs boneless skinless chicken thighs
black pepper, thyme, 2 Tbsp worcestershire sauce
sautee the onions with the garlic and ginger in the instant pot.
deglaze the pan with the broth, and add everything but the chicken and stir.
put the chicken on top, and pressure cook (manual / high) for 25m. fast-release.
next time I think I'd add a little sushi vinegar or something, it wanted some acidity. definitely a recipe that you could flavor in all sorts of ways, but the chicken was perfectly cooked and so was the rice, so i'll keep the liquid ratio.
It happens tomorrow (Saturday, March 25) from 8:30pm to 9:30pm in your local timezone. All you have to do is turn out your lights for that hour.
Please join the millions of people around the world doing this, if you can swing it.
Locals: the Cambridge Community Development Department is asking folks to participate, and will be giving out hot chocolate at the main library branch during Earth Hour to celebrate.
* There seems to be an understanding that candles, phosphorescence, and fireworks are okay? So this is Reform Earth Hour? Presumably Conservative Earth Hour is where you can have a candle or glow-stick, but only if it was lit before Earth Hour started, and an Orthodox Earth Hour where you will damn well sit there in the dark.
Oh, and for those who don't get the title of this post, the string to search is "how many Jewish mothers does it take to change a lightbulb?"
Shown above is a beautiful springtime view of Osorno Volcano as seen from Lake Todos los Santos in the Los Lagos Region of Chile. Though quiescent for over a century, Osorno erupted at least 11 times between 1575 and 1869.The symmetrical shape and snowcapped summit (8,701 ft or 2,652 m) of this stratovolcano is renown in Chile as a geographic symbol. It's also known for its resemblance to Mount Fuji, Japan.
As a result of its maritime (marine west coast) climate, Osorno's flanks receive abundant snowfall during the colder months. Glaciers cover its upper slopes -- above approximately 5,900 ft (1,800 m). Photo taken on November 21, 2016.

You know what would be awesome, Medium Game, for the Blue Nation and Obamacare? If outraged Repealists started flipping out on Replacists on Twitter, accusing anybody who espouses Replacism of being a RINO/libtard/Democratic plant/etc and attacking them for being a lazy slob who mooches off the government like those damned Democrats.Today, on CNN, emphasis mine:
Come the day that Republicans expect to be personally attacked by fellow Republicans for expressing any wish for government assistance in securing health insurance, a whole bunch of no-longer-insured Republicans will quietly cross the aisle.
I don't know that the Repealists have started doing this for us. Here's hoping.
The tug-of-war between the factions angered some other Republicans who are not part of either faction and resent their influence, like Alabama Rep. Bradley Byrne.Now we just need Red Twitter to run with it. Oh please oh please oh please.
But Byrne predicted that when the bill finally came to the floor, political reality would kick in.
"If you are a Republican you have one choice. You're either going to vote with Donald Trump to repeal and replace Obamacare or you're going to vote with Nancy Pelosi to defeat the only bill that will repeal and replace Obamacare. And if you're a Republican, that's a pretty simple choice."
A key element of the negotiations between the Freedom Caucus and the White House revolves around the so-called Essential Health Benefits. The White House is working to possibly include the repeal of Obamacare requirements that certain benefits -- such as mental health coverage, drug addiction coverage and maternity care -- be required in insurance plans.

That's it. That's the straight-up legalization of junk insurance, by the front door instead of coming in through the side.
The American Oystercatcher (Haematopus palliatus) is a striking coastal seabird noted for its bright, functional beak, designed to extract mollusks from intertidal sediments. New England populations are migratory, wintering along the American Gulf Coast and breeding along New England’s rocky shoreline. Before the mid-1800’s Oystercatchers were a very common spring and summer sight along the northeastern coast of the United States and Canada, but hunting, wild egg and feather collecting, and habitat encroachment lead to its near extinction.
Although they received government protection under the 1918 Migratory Bird Treaty Act, Oystercatcher numbers continued to decline. In the early 2000s, after the total North American population fell to fewer than 10,000 individuals, efforts to protect the species and its dwindling habitat intensified. These combined public and private habitat protection efforts have been remarkably successful, with a clear rebound in the New England population in recent years. In this image, an American Oystercatcher on Rainsford Island in Boston Harbor Islands National Recreation Area protects its nesting area with its distinctive shrill cry. Previously, its shrill cry was not enough to ensure survival, but the addition of legislated habitat protection seems to be working! Photo taken on June 6, 2015.

Mount Etna, on the island of Sicily, Italy, is erupting once again. This is the second time this month that Etna (10,922 ft or 3,329 m) has unleashed noteworthy Strombolian explosions. The second eruptive event began on the morning of March 15, 2017. The lava fountain featured above is erupting from Etna's southeast crater. When this shot was snapped, during the night of March 16, 2017, lava was flowing to the base of the volcanic cone and beginning to ooze down the south flank of the mountain.
This fiery landscape was lit from above by a waning gibbous Moon and a starry sky. The long exposure used here results in the star trails rotating about the North Star. In the foreground note that a thick snowpack lower down the mountain partially covers the volcanic landscape.

One problem: I got two copies, one to my current actual secret Patreon email address, and one to my honeypot email address - the Patreon-exclusive email address I decommissioned after I learned of the theft of creators' email addresses from Patreon about two years ago.
I checked Patreon's front page and blog and there's nothing there about this political project.
None of the links in the email actually go to Patreon.com, they go to a third party service - which is not unusual for corporate mass-mailings, but which is still... unreassuring.
I strongly recommend not clicking any of the links in the email if you get it.
I captured this beautiful display of crepuscular rays near Warwick, Queensland, Australia, at sunset on January 15, 2017. Sunlight streaming through gaps in building cumulus clouds near the western horizon form the bright rays while the dark lanes result from cloud turrets that effectively blocked the Sun. Look for rays such as this when clouds, most often cumulus clouds, are observed on the horizon where the Sun is setting. Also, look toward the opposite horizon to see if anticrepuscular rays can be detected.

It has come to my attention that some of the Blue Nation is unclear on what is currently playing out on the Right in response to Ryancare. This is terrible: you're missing out on some top-shelf schadenfreude.
A crucial confusion is, apparently, not understanding that there are several different factions over on the Right right now. If you attempt to understand what is happening over there by generalizing from all the things everyone over there does, things look very self-contradictory. I mean, even more self-contradictory than they actually are.
Before explicating the factions and their agendas, I need to take a moment to recount how it has been long much observed that messing with Obamacare wouldn't work or wouldn't be possible, because of the Three Legged Stool principle. ( The Three Legged Stool of Obamacare was... [3,700 Words] )

Featured above is an attention-getting 22 degree solar halo, an upper tangent arc (tangent to the top of the halo) and sundogs (on the sides of the halo and at the same elevation as the Sun). It was observed over Murrieta, California, on February 2, 2017. Sunlight passing through hexagonal plate ice crystals in cirrus clouds form the 22 degree halo and the arcs seen here. Because the crystals are oriented horizontally (think of a leaf as it falls to the ground) when they're positioned at the same elevation as the Sun and approximately 22 degrees from the solar disk their particular alignment allows this segment of the halo to be considerably brighter than the remainder of the halo. In addition, since the oriented crystals that form the sundog tend to be larger than the randomly oriented crystals that generate the 22 degree halo, they're generally much more colorful. Sundogs can be seen best when the Sun is low in the sky -- they cannot be viewed when the Sun attains an elevation of 61 degrees. Note also the contrail and its distinct shadow.
