			<content:encoded><![CDATA[<p><em><a href="http://www.flickr.com/photos/ethanhein/sets/72157625331251189/">See the photos</a></em></p>
<p><em></em>We took our first trip off the Kona coast and went to check out the more rugged and rural north coast of the Big Island. A lot of the drive took us up the seemingly endless lava plain that makes up the northwest quarter of the island. It looks a lot like Iceland, except it&#8217;s sunnier and there&#8217;s more shrubbery. There aren&#8217;t any big flat surfaces for graffiti, so instead the Hawaiians write their roadside messages by arranging white coral on the black lava.</p>
<p>Once we got up off the coast, the landscape got greener, hillier and a lot more agricultural. We saw cows, sheep, horses, chickens, and even some goats. If not for the tropical plants and occasional sweeping ocean views, we could have been in Vermont.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Kohala_%28mountain%29"><img class="aligncenter" title="Kohala volcano" src="http://upload.wikimedia.org/wikipedia/commons/3/36/Kohala_volcano.jpeg" alt="" width="480" height="300" /></a></p>
<p><span id="more-5423"></span>We find the economics here to be mysterious. Hawaii is so expensive and isolated, how could you possibly make a living raising goats? Are all of these farms a source of amusement for rich transplants and retirees, or are they all just fronts for lucrative pot farming, or what?</p>
<p>I didn&#8217;t think to bring the cable that connects my phone to the car  stereo, so as we do all this driving, we&#8217;re dependent on radio for entertainment. Hawaii is long on  natural beauty but a little lacking in its musical culture. The radio  is about 60% lite reggae, 25% lite pop and 15% Nashville country. Forget   about hip-hop or anything edgy, there isn&#8217;t even a classic rock  station. Thank god for NPR.</p>
<p>Our friend Katie lent us a book of hikes on the Big Island. The very first one it lists is the <a href="http://en.wikipedia.org/wiki/Waipio_Valley">Waipio Valley</a>. It&#8217;s a secluded spot between two almost vertical cliffs, with a little river snaking down to a black sand beach. The only way down is by a narrow single-lane road that you could almost rappel down. Here&#8217;s the view from the top.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Waipio_Valley"><img class="aligncenter" title="Waip'io valley" src="http://upload.wikimedia.org/wikipedia/commons/thumb/7/72/Waipio_Lookout_View.jpg/800px-Waipio_Lookout_View.jpg" alt="" width="480" height="320" /></a></p>
<p style="text-align: left;">The valley is inhabited by even crunchier hippies than the ones we met at the Kona farmer&#8217;s market. They have electricity down there, but that&#8217;s apparently a quite recent development. One of the &#8220;roads&#8221; is a six-inch-deep stream &#8212; we saw a grandmotherly white-haired lady nonchalantly drive her pickup truck up it. There seems to be some marginal tropical agriculture happening; again, how it all works financially is a mystery. It feels more like Jurassic Park than a farming community. Looming in the background is a pair of waterfalls plunging off the cliffside to feed the river. The trees are densely hung with vines, and there are colorful flowers of the kind that you see on Hawaiian shirts.</p>
<p style="text-align: left;">After we walked around the valley a little, we went out to the beach you see in the picture, which is truly epic. Not only does it have cliffs and god rays and the river winding through round porous volcanic rocks, but there are also horses roaming freely. I couldn&#8217;t tell if they&#8217;re wild or just have very laid-back owners. Anna observed that the only thing missing is rainbows and unicorns.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Kohala_%28mountain%29"><img class="aligncenter" title="Waipio bluff" src="http://upload.wikimedia.org/wikipedia/commons/thumb/6/63/Waipio_bluff.JPG/800px-Waipio_bluff.JPG" alt="" width="480" height="360" /></a></p>
<p>We dragged ourselves back up the cliffside road and drove up to the nearby <a href="http://en.wikipedia.org/wiki/Kalopa_State_Recreation_Area">Kalopa State Recreation Area</a> to take in some more nature before it got dark. It&#8217;s a forest preserve with a lovingly maintained rainforest arboretum, and we basically had the place to ourselves. The park brochures are charmingly earnest and old-school, written on a  typewriter. They&#8217;re dated 1992 but could easily have been written in  1952. There are trees with rainbow-colored bark and pink leaves, and prehistoric-looking ferns. The ground is littered with smashed guavas, making the place look like a tragic accident at the smoothie factory. We saw a lot of mongooses slinking around, and a couple of pheasants, descended from birds inexplicably imported from Nepal.</p>
<p>Before we left we stuffed our suitcases with bulk food and power bars from the <a href="http://foodcoop.com/">Food Coop</a>, and we&#8217;ve been cooking all of our meals since we got here. But after all the hiking we finally had our first dinner out, and it was a classy one, at <a href="http://www.merrimanshawaii.com/">Merriman&#8217;s</a> in Waimea. The high-end locavore movement was late in arriving to Hawaii, but now it seems to have fully taken root, and Merriman&#8217;s is holding the banner high. We ate all kinds of local treats: pickled passionfruit, sauteed ferns,  ahi, pork, lamb, and the most expensive and sensationally delicious cups  of coffee of our lives. It was like boiled dark chocolate bars. In the movie of our trip, our waiter would be played by Johnny Depp in full manic mode. He had a Fu Manchu beard and his thumb and pinkie nails were painted a shiny turquoise. I asked him what the story was there and he explained without a trace of irony that it was to widen his <a href="http://en.wikipedia.org/wiki/Shaka_sign">shaka</a>.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Shaka_sign"><img class="aligncenter" title="Shaka sign: hang loose, dude" src="http://upload.wikimedia.org/wikipedia/commons/4/42/Gesture_raised_fist_with_thumb_and_pinky_lifted.jpg" alt="" width="360" height="240" /></a></p>
<p style="text-align: left;">The tiki motif is getting old, but the music was nice, including a gorgeous lap steel instrumental version of <a href="http://www.youtube.com/watch?v=4qoymGCDYzU">&#8220;Wichita Lineman.&#8221;</a> Way better than cheesy reggae.</p>
<p>The next day we got up bright and early to go on an organized snorkeling trip run by <a href="http://www.seaparadise.com/">Sea Paradise</a> in <a href="http://en.wikipedia.org/wiki/Kealakekua_Bay">Kealakekua Bay</a>, the site of the <a href="http://en.wikipedia.org/wiki/James_Cook">Captain Cook</a> monument. We had wanted to hike down there, but development on the coast has made that difficult, and it turned out to be better to see it from the water anyway. Sea Paradise took us out in a catamaran, and I want to pause to enjoy that word. Catamaran. Catamaran! It&#8217;s fun just typing it.</p>
<p>We had a good couple of hours bobbing around the bay among the banyan trees and giant boulders, gawking at the psychedelic fish and coral. It&#8217;s like being in a screen saver. If you&#8217;re interested in how complex forms emerge and self-organize through natural selection, there&#8217;s no better place to see it in action than in the ocean around Hawaii. The patterning on the fish is a dazzling display of <a href="http://en.wikipedia.org/wiki/Cellular_automaton">cellular automata</a> and <a href="http://en.wikipedia.org/wiki/Reaction%E2%80%93diffusion_system">reaction-diffusion</a>. Steven Wolfram would be in heaven.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Parrotfish"><img class="aligncenter" title="Parrotfish" src="http://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Bicolor_parrotfish.JPG/800px-Bicolor_parrotfish.JPG" alt="" width="480" height="360" /></a></p>
<p style="text-align: left;">The magic isn&#8217;t just that the fish are so colorful and groovy, or that there are so many of them. It&#8217;s that they&#8217;re mostly so unconcerned by human presence. A few fish avoided us but most went about their business as if we weren&#8217;t there. The needlefish especially were willing to hang in my face making prolonged eye contact.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Keeltail_needlefish"><img class="aligncenter" title="Keeltail needlefish" src="http://upload.wikimedia.org/wikipedia/commons/e/e7/Keeltail_needlefish.png" alt="" width="439" height="113" /></a></p>
<p style="text-align: left;">The weirdest thing I saw all day was a crown-of-thorns starfish. It took me a while to figure out whether it&#8217;s an animal, a plant or a particularly weird coral shape. It&#8217;s a good foot wide at least.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Crown-of-thorns_starfish"><img class="aligncenter" title="Crown-of-thorns starfish" src="http://upload.wikimedia.org/wikipedia/commons/thumb/8/8f/CrownofThornsStarfish_Fiji_2005-10-12.jpg/480px-CrownofThornsStarfish_Fiji_2005-10-12.jpg" alt="" width="480" height="600" /></a></p>
<p style="text-align: left;">It&#8217;s a depressingly recurring theme: spectacular exotic creature turns out to be invasive or in some way harmful to Hawaii&#8217;s delicate ecosystem. The crown-of-thorns starfish isn&#8217;t an invader, but it is a problem. It eats coral, putting more pressure on the already beleaguered reefs, and its natural predator, the conch, has been fished nearly into oblivion.</p>
<p>Snorkeling is fun but exhausting. Two hours of it plus a boat ride on other end completely wiped us out. We mostly spent the rest of the afternoon sleeping.</p>

			<content:encoded><![CDATA[<p id="firstHeading"><em><a href="http://www.flickr.com/photos/ethanhein/sets/72157625331251189/">See the photos</a></em></p>
<p>First of all, what are we even doing here? Anna&#8217;s dad had been sitting on a timeshare for years, and he finally concluded that he was never going to use it. So he offered it to us, and we thought, great, Hawaii. Anna&#8217;s been before, but I haven&#8217;t been anywhere remotely tropical, much less here. So we decided to use up the last of Anna&#8217;s frequent flier miles from her former life working for international NGOs, and here we are.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Hawaii"><img class="aligncenter" title="Hawaii as seen by NASA" src="http://upload.wikimedia.org/wikipedia/commons/thumb/6/6b/Hawaje-NoRedLine.jpg/771px-Hawaje-NoRedLine.jpg" alt="" width="463" height="360" /></a></p>
<p>We flew out of Boston because there weren&#8217;t any mileage flights available from NYC. Besides, it was a chance to see my cousin Jen and meet her new baby. We spent a jolly night, and the next morning Jen took us to Logan. We landed in Kona after our twelve hours of plane and airport time. Kona doesn&#8217;t have jetways; we walked down stairs to the tarmac. It&#8217;s been a while since I did that, it made me feel like one of the Beatles. Kona&#8217;s airport is open-air, with a roof but no walls. It was nice waiting for our luggage at the baggage claim in a gentle tropical breeze.</p>
<p><span id="more-5358"></span>We&#8217;re staying in a condo in the midst of the most tourist-packed, overdeveloped strip of the Kona coast. Nevertheless, we woke up to an incredible variety of birdsong. Just looking out the window, we saw mynah birds, saffron finches and red-crested cardinals. It was kind of a buzzkill to read how all of these birds were introduced to Hawaii and have severely crowded out the native species. Still, they&#8217;re pretty.</p>
<p><a href="http://en.wikipedia.org/wiki/Saffron_Finch"><img class="aligncenter" title="Invasive bird" src="http://upload.wikimedia.org/wikipedia/commons/1/1c/Safron_finch_27.jpg" alt="" width="504" height="346" /></a></p>
<p>The first order of business today was to go into town to rent some gear from <a href="http://snorkelbob.com/">Snorkel Bob&#8217;s</a>. The web site is well worth a visit if you&#8217;re a fan of idiosyncratic copyrighting &#8212; Bob is fond of referring to himself in the third person. Eccentric though his business persona may be, Bob is admirably committed to ocean conservation and has some pretty tart criticism for aquarium enthusiasts. Have to say that I agree with him.</p>
<p>We planned to start our Hawaii experience proper with <a href="http://en.wikipedia.org/wiki/Pu%27uhonua_o_Honaunau_National_Historical_Park">Puuhonua O Honaunau National Historical Park</a>. The drive was rich with Hawaii-ness &#8212; we passed two ukelele stored in a hundred yards. On our way there we took a wrong turn and wound up at the Kona farmers&#8217; market. I was abstractly aware that Hawaii has hippies, but this farmers market makes the <a href="http://foodcoop.com/">Park Slope Food Co-op</a> look like a Trader Joe&#8217;s in suburban Connecticut. Think anglo dreads, tribal tattoos, dogs in pickup trucks. A guy selling enormous breadfruit was excitedly talking about going on tour with <a href="http://en.wikipedia.org/wiki/David_Nelson_%28musician%29">David Nelson</a>, a member of Jerry Garcia&#8217;s extended orbit. While we shopped, we were serenaded by a hippie farmer&#8217;s vague approximation of &#8220;Mother Nature&#8217;s Son&#8221; by the Beatles, played on a National steel guitar in open D tuning. A woman selling exotic vegetables of various kinds was also selling CDs by one Father Bubba. Of the ten songs, nine were titled after Bible verses, and the tenth was called &#8220;Jerry&#8217;s Gone.&#8221;</p>
<p>So, Puuhonua O Honaunau National Historical Park. It&#8217;s out on the end of a big flat lava plain. Plants like this kind of terrain, I assume because lava rock is so porous, so the vegetation is lush and dense. There are coffee and macadamia plantations and people&#8217;s fancy beach houses are surrounded by all kinds of exotic tropical foliage in bright colors. The coastline around the park is all black lava rock in fantastic fractal shapes. It&#8217;s like taking a walk around the <a href="http://en.wikipedia.org/wiki/Mandelbrot_set">Mandelbrot set</a>. In places the rock is attractively set off by white coral sand.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Kona_District,_Hawaii"><img class="aligncenter" title="Kealakekua Bay" src="http://upload.wikimedia.org/wikipedia/commons/e/ea/KealakekuaBay.JPG" alt="" width="504" height="378" /></a></p>
<p>The park has some historic <a href="http://en.wikipedia.org/wiki/Heiau">Hawaiian temples</a>, but the main attraction for me was the wildlife. I&#8217;ve never been anywhere with this kind of marine biological density. Just poking around the beach and tide pools, we saw crabs, sandpipers, a rainbow of fish and two sea turtles.</p>
<p>So then, snorkeling. It&#8217;s pretty magical. One second, we&#8217;re fumbling with the masks and flippers at the water&#8217;s edge among a bunch of other Americans in swimsuits like on any other beach. Then all of a sudden it&#8217;s like being dropped in the giant coral reef display at an  aquarium. In the first ten minutes out there were coral, sea urchins, <a href="http://en.wikipedia.org/wiki/Moorish_idol">Moorish Idols</a>, <a href="http://en.wikipedia.org/wiki/Yellow_tang">yellow tang</a> and parrotfish. The high point was chasing a three-foot <a href="http://en.wikipedia.org/wiki/Needlefish">needlefish</a> around its slow-paced routine.</p>
<p style="text-align: center;"><a href="http://en.wikipedia.org/wiki/Needlefish"><img class="aligncenter" title="Needlefish being cleaned" src="http://upload.wikimedia.org/wikipedia/commons/thumb/2/21/Needlefish_is_being_cleaned_by_Labroides_phthirophagus.jpg/800px-Needlefish_is_being_cleaned_by_Labroides_phthirophagus.jpg" alt="" width="480" height="242" /></a></p>
<p>Snorkeling is also terrifying. Just breathing with my face in the water took some convincing of myself, that&#8217;s a pretty deep reflex that needs to be overcome. I didn&#8217;t quite get used to hearing my own breathing resonating so loudly in my head. Also, getting tossed around by the surf so close to so many jagged rocks was unnerving. We swam all of a hundred fifty feet, but it was enough action for an afternoon. People who scuba dive: you are crazy. Humans have no business underwater. Still, I&#8217;m looking forward to doing some more admiring from the surface level.</p>

			<content:encoded><![CDATA[<p>Life appeared very early in the planet’s history, earlier than you might have naively guessed. But then for billions of years, it existed only as simple single cells floating in the ocean or sitting in cracks in the rocks. Big complex creatures visible to the naked eye didn’t appear until the planet was two-thirds of the way to its present age. The first insects didn’t appear until nine-tenths of the way to the present, and humans didn’t show up until ninety-nine percent of the way.</p>
<p>Our creation stories start with the assumption that we’re the most important thing in the world, the reason for everything else’s being. The story that science tells relegates us to the periphery. Life has mostly been smaller and simpler than us. I think it&#8217;s important to recognize that we might very easily wipe ourselves out, and the microbes will barely have noticed we were even here.</p>
<p style="text-align: center;"><a href="http://upload.wikimedia.org/wikipedia/commons/7/79/Geological_time_spiral.png"><img class="aligncenter" title="Geological time spiral" src="http://upload.wikimedia.org/wikipedia/commons/thumb/7/79/Geological_time_spiral.png/678px-Geological_time_spiral.png" alt="" width="407" height="360" /></a></p>
<p><span id="more-3812"></span>Seeing numbers with nine zeroes in them doesn&#8217;t help in imagining the time scales involved here, so I&#8217;ll also use the convention that the entire history of the Earth is taking place in one day. In this analogy, one &#8220;hour&#8221; on the clock is about 192 million years.</p>
<p><strong>midnight (</strong><strong>4,600,000,000 years ago)</strong></p>
<p style="padding-left: 30px;">Earth forms from space dust left over from the new <a href="http://www.ethanhein.com/wp/2010/here-comes-the-sun">sun.</a></p>
<p><strong>12:21 am (</strong><strong>4,533,000,000 years ago)</strong></p>
<p style="padding-left: 30px;">Earth collides with <a href="http://en.wikipedia.org/wiki/Theia_%28planet%29#Theia">the planet Theia,</a> causing rings of debris to form. The rings last for millions of years until they coalesce to form the Moon. (Check out <a href="http://www.youtube.com/watch?v=UT2sQ7KIQ-E">this fun visualization</a> of what the modern Earth would look like with rings.)</p>
<p><strong>2:36 am (</strong><strong>4,100,000,000 years ago)</strong></p>
<p style="padding-left: 30px;">After a lot of volcanic excitement, the surface of the Earth cools enough for the crust to solidify. The atmosphere and oceans form.</p>
<p><strong>3:08 am (</strong><strong>4,000,000,000 years ago)</strong></p>

<p style="padding-left: 30px;">DNA emerges and quickly out-replicates whatever other self-catalyzing chemical reactions are happening. During this time, the atmosphere has no free oxygen.</p>

<p><strong>8:18 am (</strong><strong>3,000,000,000 years ago) </strong></p>
<p style="padding-left: 30px;">Photosynthesizing bacteria evolve. They release the first free oxygen into the atmosphere, which is a poison for a lot of other bacteria.
