Hebes Chasma

Run, do not walk to the ESA website and download the magnificent image of Hebes Chasma on Mars:

HiRISE picture of the Hebes Chasma on Mars

This is an extremely deep chasm (8000 meters deep — that’s nearly as deep as Mt. Everest is tall!) almost smack on the Martian equator, at the northern tip of the grand Valles Marineris, the canyon on Mars that’s as wide as the Grand Canyon is long, and as long as the United States. This image from the high resolution camera on Europe’s Mars Express has a resolution of 15 meters/pixel, so if any martians are playing tennis, you could just make out the court. They even have an anaglyph!

Universe Today (make sure you Digg that article, not mine!), where I saw this first, has more info.

That image is stunning, fantastic. It may even edge out my other favorite Mars picture, and it’s certainly a contender for my Top Ten pick of the year.

Wow.

6000 years of Republican debates

If you read my blog, you probably read other blogs that promote science and try to stamp out antiscience. If so, you’ve probably seen or heard of this incident last night in the Republican presidential debates, where the moderator asked the candidates who "does not .. agree/believe in evolution". Three candidates raised their hands.

I am not sure how to feel about this. As familiar as I am with antiscience in this country, I’m still appalled that anyone who would run for office would state that they think evolution is wrong. Even after six years of this White House, I am still shocked to see such a flagrant attitude against reality.

Maybe I should be happy that it was only three of them. Given that anti-evolution is a platform in some states’ Republican parties, a 30% disavowal rate of reality maybe isn’t so bad.

I’m certainly not surprised at the three who did raise their hands: Brownback (Kansas, natch), Tancredo (from Colorado; my work will be cut out for me when I move, certainly– though he’s not from my district), and Huckabee (Arkansas). McCain equivocated, saying he thinks evolution is real, but then pandered a bit to the young-Earth base by talking about religion and the Grand Canyon.

I remember when the Republican party stood for strong science. It doesn’t even seem that long ago. Wow.

I will be very interested to see what the Democrats have to say on this same issue. I don’t think too many of them will make a strong stand, since it seems these days that every politician feels the need to twist in the wind, and face whatever way each breeze blows. Al Gore has made some particularly galling comments lately, too. Update: Gore may have not been as serious as many say.

I am not a one-issue voter, but peoples’ attitudes toward science — toward reality — is very telling on many of their other attitudes.

And say it with me: evolution is not a belief system! You cannot believe in it or not. It is a matter of scientific fact. It exists, it is real, whether you stick your fingers in your ears and sing la-la-la or not.

Update: Chris Cillizza has written about this on the Washington Post blog. The comments are interesting. Thanks to Derek of Skepticality for the tip!

6000 year old rock

Note: I am still recovering from TAM 5! I will try to sit down tonight and get a good entry written about it. But until then, I have some other things to say.

What with the Grand Canyon stuff still going on, I sometimes find people asking what the big deal is. Why worry so much about a book that says the Grand Canyon is only 6000 years old?

Besides the obvious — the book is dead wrong, it is antiscience, it is in violation of the First Amendment, and the National Park Service has been very dodgy about doing anything about it — young Earth creationism garbage does real damage to people’s ability to discern reality from fantasy.

Lauren Becker, a science interpreter who has taught at museums and parks around the country, says it better than I do: She wrote an essay for CSIPCOP about it that’s wonderful. Read it, think about it, discuss it below.

Tip of the ranger hat to Johnny Five for the link.

More on the Grand Canyon

Note: I meant to publish this post last week, but somehow it slipped between the cracks. It should have gone up before this post for sure. Sorry about this.

Through Northstate Science comes the tip that Kurt Repanshek has posted about the PEER press release on creationism at the Grand Canyon on his blog, National Parks Traveler.

If you don’t know about this issue, you can read what I wrote here and here (though maybe in reverse order would be better).

Kurt has a rather devastating list of evidence against the PEER group, showing the press release to be pretty far off the mark. I disagree with one conclusion though:

Now, one piece of PEER’s release that comes pretty close to standing up is the group’s claim that the Park Service has failed to review the propriety of the park’s bookstores to sell “Grand Canyon: A Different View.” This book, by Tom Vail, claims that the Grand Canyon was created by the great flood that forced Noah to take to his ark. PEER would like it banned from the park.

[…]

Now, I say the claim “comes pretty close” to being true because the book has indeed been discussed within the agency but no final, official, decision has been reached by the agency’s Office of Policy.

I think that part of PEER’s release is dead on. The NPS has taken three years to review this problem, which is too long even for the government to move. This is not a difficult problem to understand or to solve. In fact, there are several solutions:

  • Remove it from the store.
  • Sell it, but under the "myth" section.
  • Put a sticker on it saying "The contents of this book are speculative, and in fact are indeed provably wrong. The authors are not well (or, apparently, at all) versed in the scientific method, the best way through which to test the nature of reality. The authors put their personal beliefs ahead of facts. In case you are still not clear, this text should be thought of as a religious tome and therefore cannot be endorsed by any branch of the U.S. Government."

You get the idea.

However they wanna do it, they could do something. Stalling is not the answer, and in fact will bite them on their collective butts. The nibbles have already begun.

Grand Canyon issue resolved… but not really

Christopher O’Brien over at Northstate Science has the details.

I am shocked, shocked, to hear that there is more to this story, including duplicitous park administration officials, after-the-fact massaging of decisions, and that PEER still hasn’t apologized for being incredibly slimy about this.

Try reading these posts for the background story.

More on the Grand Canyon

I’ve been getting a bit of email about my blog entry about creationism being promulgated at the Grand Canyon.

First, a correction. Sorta.

Reading the original PEER press release, I thought that it said that National Park Service rangers were being forbidden to give the actual age and history of the canyon when asked, so as not to offend religious patrons. Why did I think that? Probably because the PEER press release says:

“In order to avoid offending religious fundamentalists, our National Park Service is under orders to suspend its belief in geology,” stated PEER Executive Director Jeff Ruch. “It is disconcerting that the official position of a national park as to the geologic age of the Grand Canyon is ‘no comment.’”

However, Jeff Hebert asked the PEER folks if this were actually true. They responded:

Jeff–

This option is the closest–

"Are you simply saying that the NPS hasn’t offered an official guideline to its employees as to how they are to answer that question, and not that the official position is to answer “no comment”?"

1. Reports from Grand Canyon NP interpretive staff, some of whom have been seeking clarification from their chain-of-command relative to questions about the validity of “young earth claims.” The more than three-year hold-up in blocking official guidance on this question is part of this concern.

2. Statements by NPS HQ officials that the creationist view should be given equal time in park materials.

3. The reply from the Grand Canyon superintendent’s office to media inquiries on the official park view on the age of the Canyon.

We did not mean to imply that geological information has been deleted from park materials.

I have read over this many times, and no matter what I do, it sounds to me like PEER’s press release was written specifically to make people think that rangers were told to give the answer "no comment". Now, PEER is saying they never said this. This is pure spin at the very, very least.

Here’s the deal. The Grand Canyon visitor’s center is selling a creationist book, which is highly unconstitutional, and there is pressure from White House appointees to not only sell it, but apparently also to bury any reviews of the situation. This Administration promised three years ago to investigate the book being sold, and nothing has been done.

That, to me, is bad enough. There is no need to exaggerate the issue. Yet it looks to me like PEER did just that. They made it sound even worse, and stretched the truth to do so.

PEER needs to make another press release, and it needs to include an apology for their slimy behavior. They have made this situation worse, because now it emotionally weakens the argument for truth. Reality-based people — like me — now have to say we were wrong.

I am saying it now. I was wrong to say that rangers were being gagged. It is my fault for relying on a press release, pure and simple. I’m glad my friend Wes Elsberry was smarter than I was on this.

But PEER needs to admit they screwed up, too.

This still leaves us with the issue of the book, and with that I am certainly not backing down.

You can read far more about this terrible book at the Free Inquiry website. Bob Carroll at the Skeptics Dictionary has something to say about it, as does, again, Wes Elsberry. Creek Running North has a wonderful geological timeline of the Grand Canyon, too, where you get the real picture of what formed the canyon.

Actually, let me say again to read that timeline. The canyon was formed through forces both subtle and gross, land-building events that took millions of years. Countering that are erosive forces that work over those same eons, and sometimes at much faster rates. Primitive life took hold in those rocks billions of years ago, and life both uni- and multicellular still exists there. All of this, and more, is written in the rocks, in fine detail with a rich, lush history.

Yet there are those who would prefer to think the canyon was swept into existence through divine interference, all at once, despite all (and I mean all) the evidence against that.

Think about the oversimplified fantasy of Noah’s flood and then compare that with the complex and subtle nature of the reality of the canyon as Creek Running North described. Creationists love to say that scientists lack the appreciation of beauty and have no sense of awe, but you tell me: whose canyon story is more beautiful, whose is more interesting, whose is more awe-inspiring, and has more detail, evidence, and self-consistency?

Creationists deny all this because they have to. If they accepted it, they’d realize they’re wrong, and they cannot accept that. They claim their rock-solid faith makes them strong, but in reality it makes them weak, brittle. They cannot learn, they can only deny, deny, deny.

And this is what we want to teach people when they visit the grandest canyon on Earth?

Science linkies

Update! See You at Enceladus has the 51st Skeptics Circle posted, and I have two entries there, including one about the Grand Canyon. That story is still unfolding, and I will have more about that very soon. Stay Tuned.

The Philosophia Naturalis science blog circle has been posted at Highly Allochthonous, a blog whose title is harder to pronounce than "Pharyngula".

Anyway, my entry on the length of the year is there, as well as lots of other cool science geeky readable thingies.
