Galapagos day 10 – Cruise day 5 – Western Isabela Island




I asked Juan today about his impressions of how the protest went. He estimated there were 200 people in attendance – tourist guides, employees of the National Park, their families, and average citizens. He said the mayor spoke at the demonstration and is on their side.

He explained that the Ecuadorian air force controls both the Baltra airport on the Galapagos, and they control the gas station, where international and local ships refuel. He says the air force sells gas at the set price to the local ships. But when international ships come in, they sell gas at a higher price. According to Juan, none of this hits the books. Effectively, they are stealing gas and making money from it.

He said that tomorrow, a commission will be going to the Baltra airport and turning over control of the airport and the gas station (la capitania) to the local government. The air force (about 100 members) will remain only for military functions.

“Our constitution doesn’t allow for the military to control anything like an airport or a gas station. All other airports in Ecuador are under local government control. It is only here because Baltra started out as a military base. They got used to controlling it and they have interests tied in with local politicians that has made it hard to take the control away.”

“Will this be a peaceful transfer?” one of our shipmates asked.

“Of course,” Juan said. “There are 15,000 residents of Puerto Ayora and only 100 of them. For their sake, it must be a peaceful transfer.” He of course forgot that those 100 are probably better armed than the 15,000. The members of the commission are courageous people.

But that’s what I like about Juan – his passion for the environment, for the park, and for education of the young. I like his confidence that something can be done and his commitment to playing a role in the changes.

Last night we sailed all night, for over 9 hours, to get to the western side of Isabela Island, the largest island in the archipelago. No more than 30% of the cruise ships reach this region, due to the long cruise. And so we are much more alone in nature here.

Of course, I appreciate the scenery and the ability to see animals. But the newness of seeing the most common species – the sea lions, the crabs, the turtles, the iguanas, the blue-footed boobies, the frigate birds – has worn off. I appreciate greatly the knowledge we receive from the guide. But rather than walking slowly over a short distance, I find myself aching for some kind of a goal, for something a little more strenuous, a little more challenging. While the schedule is relatively busy, I think it’s the lack of initiative and creativity required from me that’s beginning to bore me. I think I would have been better off with a five day, rather than an eight day tour.

What we did see today was marvelous though. We started off at Punta Moreno, walking across a black lava field – one of the most barren environments I’d ever come across. We could see two volcanoes – Sierra Negra, which we’d summitted last week, and Cerro Azul, both contributors to the ropy knots of solidified basalt we were stepping over. The silica in the basalt (40%) gave it a crunchy, glassy sound as we stepped over it.

This was a place to see how life developed from the beginning. There we were, in a most inhospitable environment – lava rock, ocean, and burning equatorial sun. Yet, in the less than 1,000 years since the last major lava flow, life was developing. This was especially evident around the brackish lagoons, green oases amidst a desert of black.

To me, this was a visual lesson, an analogy, of how things could have evolved after a big bang. For the first time, I understood the baby steps that led to an environment of verdant vegetation and abundant wildlife.

Only a few plants are capable of colonizing in such an environment – Galapagos sedge, candelabra cactus, grasses, and mangroves. These pioneer plants survive and create the soil for secondary plants, more complicated growths. Some plants, such as mangroves, attract insects, which then brings small invertebraes that feed on the insects. The lava cactus is another pioneer plant that uses the strategy of use its parts to generate itself. As parts fall off, they become part of the soil. I found it a fascinating and amazing process, so slow, but the effects, when looking at the islands of different ages, are so strong over millions of years.

We paused at a pond of brackish water, green around the edges, where life was concentrated. Another sinkhole, carpeted in green, stood out brilliantly against the harsh pahoehoe and aa lava. There were a few flamingoes in the water. A feral cat, which feeds on fish and lives on the brackish water, darted through the brush. There were flyless cormorant, the Galapagos martin, a more hen, and blue wing teals. In another little pond, we saw a yellow tail mullet. He’d been trapped in there as larvae, when the waves washed up through rock cracks. And now he had outgrown the pond, but had nowhere to go. And the Park policy of non-interference with the natural process (except when doing things like repopulating tortoises and shooting goats, rats and feral cats) means that tourists will pass by and watch as he eventually expires.

This island was fascinating not for the quantity of life, but rather for its scarcity, and the amazing conditions under which that life appeared.

We motored a bit further north during lunch, to Elizabeth Bay. There, we took out the dinghies for a three-hour ride through the mangroves. In the dark, quiet, mangroves, we found a “tree lion,” (a sea lion lying on a mangrove tree), many Great Pacific sea turtles swimming gracefully underwater, several rays, and penguins. Along with the gentle swish of the paddes, we heard the singing of yellow finches, warblers and great blue herons.

One fun scene was watching a group of blue-footed boobies diving together for fish. As soon as one made the move, all the others followed suit. By cooperating in this way, they gave the fish less time to disperse. And they figure that the waves produced from the first bird diving would bring other things to the surface. They nose dive from a substantial height and it was quite remarkable to see the splashes like bangs of a repeatedly fired gun, then the birds skidding across the water as though they were on waterskis. Above, the pirates of the sky, the large, black frigate birds, loomed ominously, looking for someone to intimidate or steal from.

A little ways out into the ocean stood three red rocks, made of terracotta tuff cone. These rock faces, covered with a thick layer of white guano, were teeming with animal life – penguins (the second smallest penguin in the world and the only one to live in a tropical environment), sea lions, iguanas, blue-footed boobies, flyless cormorants. Out in their own remote corner of the world, it was nice to know that once we leave, they will go on with their existence and their role in promulgating the Galapagos ecosystem.

Galapagos days 4 and 5 – Sierra Negra Volcano and Puerto Ayora




We’re back on Puerto Ayora, having returned on the daily 16-passenger fiberglass boat from Isabela. We stopped at the Western oriented cafĂ© near the dock for a welcome breakfast of whole-grain pancakes with tropical fruit and tea with milk.

Puerto Ayora, the closest thing the Galapagos has to a capital, seems like a center of civilization. It was a treat for us to return to our simple, but air-conditioned room, internet access, laundry service, much as we loved the beauty and isolation of Isabela.

Yesterday was a rough day for us. We’d both become completely fried by the equatorial sun during our 15-kilometer hike on Tuesday. So yesterday we were in pain with the back of our knees scalded bright red by the sun. It would have been nice to rest, but we couldn’t give up the opportunity to see the Sierra Negra volcano, which we’d heard we could ascend by horseback, so we went ahead and joined a tour.

I was surprised when a truck picked us up and the guide who was driving told us to get into the open air back, where two benches lined the flatbed. In our condition, we couldn’t sit out in the open sun for an hour each way, so we asked to cram into the front seat with the driver.

There are only three towns on Isabela, the main beach town of Puerto Villamil (pop. 2200), a farming community of 500 called San Tomas, and a tiny town that I never saw on any maps called Las Mercedtitas. The island is a vast plot of empty land – a fact we were able to appreciate when we climbed up to the observation tower yesterday and saw only ocean, volcanoes, mangroves, lava fields, and scrubby forests extending as far as the eye could see. On this trip, we were heading north to the area of San Tomas.

As we packed the cracked lava strewn earth, prickly cactuses rising from the hard rocky earth, I wondered how and what people farmed. After we’d gone a ways, trees covered with Spanish moss appeared, and then dense greenery, including the upside-down hanging angel trumpet flowers. Our guide explained that the winds blow from south to north. And for that reason, the soil is blown to the north, so that the southern parts remain dry and barren and the areas available for farming (pineapple, tomatoes, potatoes, corn, bananas) are in the north.

I somehow expected there wouldn’t be many people at this remote spot on an isolated island. But I was wrong. We pulled up with a bunch of other trucks filled tourists filling the backs. We gaggled together at the base of a hill, like a flock of chickens, and waited as we were assigned our horses.

The trip was pretty disappointing, as the guides herded us up to the crater, whipping our horses to speed us up. They wanted us to finish up and get on to their next, afternoon, tour. It didn’t matter if some of the horses (including mine) bucked in response to the whipping. They also cut out our planned hike to the Cerro Azul volcano.


But despite the poor guiding, the landscape was beautiful. We rode up green hills to arrive at a vast, black crater – the crater of the volcano Sierra Negra. It’s the second largest crater in the world, after Ngorogoro in Tanzania. I’m lucky to have seen both and what a difference. While Ngorogoro is crawling with giraffes, rhinos and flamingos, the Sierra Negra is pure black basalt, with visible fissues.

The last explosion, at the rim of the crater, happened on October 22nd, 2005. they guides saw small explosions, then bombs. Many of them came up to the crater to watch the pyrotechnics during the 15 day explosion.”

I asked the horse owner, Juan, a cowboy in a red, white, and blue bandanna, weathered skin and gold teeth, whether he was scared. “A little,” he said, “But we have a stronger curiosity. When it erupts we all come up and look.”

He said the eruption brought tourists night and day. “We pray to God for more eruptions so that we’ll have a lot of work,” he said.

On our way back to town, we stopped by the Tortoise Center to learn about the efforts the center is realizing to reproduce and repopulate Isabela Island with tortoises. On the island, each volcano has a different race of giant tortoise. Of the 12 species worldwide, five of them live on Isabela. But with time, they have become more and more rare.

In the 16th and 17th centuries, pirates killed thousands of tortoises for food. After Isabela was colonized in the late 1800s, the first inhabitants also ate tortoise meat and exported their oil to the mainland. As well, they introduced animals, such as pigs, cats, rats, burros and goats, that changed the natural environment. The population steadily decreased. The newborns, with their soft shell vulnerable to attack by cats and rats, had a hard time surviving. So the center opened, to keep newborns in pens, weigh and measure them every three months, and then put them out in the wild when they are able to resist attack.

That evening, the island held the Miss Isabela pageant, the first stage in the journey to become Miss Galapagos, then Miss Ecuador, then Miss Universe. As elsewhere in Latin America, being a beauty queen is a big deal.

There were only four contestants on this small island. But an entire parade was organized in their honor. A young woman who lived in a house next to our hotel was a participant (and the eventual winner). I watched her and her family decorate the back of a pick up truck with stuffed sea lions. Then she put on a banner and took her place.

Residents lined the street as the police led the parade. The four pick-ups came by, each carrying a contestant (they seemed to be 16 or 17 years old). After those initial glances, the entire town seemed to gather in the town hall for the pageant. This was a full-fledge production that took hours to set up, complete with vendors of cold bottled beer and roasted chicken and beef.


We watched the candidates parade out in a variety of skimpy clothing. We watched a young girl dressed in pink, perhaps ten years old, perform sexy dancers with a great confidence in her ability. And we watched the national costume show, in which each contestant came out in a costume she designed that represents Isabela Island. Each was more outlandish and outrageous than the next. Rosita, our neighbor and the eventual winner, came out last, carrying a fishing pole, and wearing a bikini while balancing a giant mackerel that curved from her hips to her head.

When it became clear the contest would last well into the night, we prepared to leave. When a balloon lit by fire was released in the wrong direction of wind, flew up to the center of the covered station, and began to burn, we hastened our exit. Getting trapped in a packed, burning stadium full of beauty pageant enthusiasts wasn’t something we wanted to experience. Luckily, we heard later, the fire went out before the stadium caught aflame. And the pageant went on.
