The Tunnels – Isla Isabela, Galapagos

tunnelsP2210018
We signed up for a boat tour of the ‘Tunnels’ ($80 per person, 5 hours). On the way down to the south end of the island we were about 2 1/2 miles offshore in dead calm when the driver stopped the boat so we could check something frolicking in the water. It was 3 or 4 Manta Rays. These beasts get up to 22 feet wing span. The one in this picture is traveling under the boat, hence my shoe in the image, and is probably about 15-18 feet wing span.tunnelsP2210010
tunnelsP2210001 The top side is mostly black and the underside here in this picture is white. They are magnificent creatures who amazingly eat plankton by filter feeding – up to 60 lbs a day. Just seeing these guys offshore made the tour worth it.

To get into the Tunnels they drive the tour boat at high speed through the breaking surf line. That’s Dwyer from s/v Rascal filming with his GoPro. He’s a single-hander who made it here, Isabela island, from Huatulco, Mexico – about a 1,000 mile passage. He’s heading to Chile via Easter Island in a few weeks. His goal is to go do some remote back country skiing off his boat from the Chilean canals.
tunnelsG0141294 The tunnels are made up of volcanic lava with dozens of arches, above and under the water. These are the remnants of lava tubes formed during volcanic eruptions. Isla Isabela is made up of 5 semi-active volcanoes and the landscape is all volcanic rock.

The barren land makes for good boobie hangouts.

The penguins at this end of the island are apparently a long way from any dry-cleaners – they were all having bad hair days.

Lot of underwater volcanic caves for the fishies to hide in.

This one is hard to make out, but it is a seahorse,about 4-6 inches tall, sitting in a crack in the lava about 12 feet under.

A big green turtle moving close by underwater. These guys weren’t the least bit skittish, unlike so many of the turtles we’ve seen in other places. They’re accustomed to the tourists and seem to understand that they’re part of the show here.

That’s Chris getting up close to the same turtle.

This place is famous for the white-tipped sharks who come to the shallows to rest in the underwater caves.

Can you guess why they call them white-tipped?

The Wall of Tears

isabelaIMG_9716

We rented bikes in town (at $2 per hour) to ride out the 7km dirt trail to El Muro de las Lagrimas – The Wall of Tears. The wall was built by convicts that were kept on the island – before tourism was such a hit – from 1946 to 1959. The wall is completely purposeless, except to make the life of the convicts even worse. It is an impressive dry-stack, but you really would have thought that the prison commandante could have come up with a project that at least furthered his needs. The wall goes from one side of a small valley to the other and does nothing. I’m sure somewhere near here you could find a fairly large unmarked grave of the inmates who never made it out.

isabelaIMG_9712 Free range tortoises were along the road where there was shade under growth.

The park has put in helpful interpretive signs like this one – No tortoise petting.

isabelaIMG_9723

And for those of us with long hair, there was some demonstration signs of how to take the down hills.

isabelaIMG_9705

Its kind of hard to see, but the background peninsula is covered with blue-footed boobies. The bike trail runs along the ocean for most of the way till it heads up hill to get to the prison site. Which, for me, conveniently made it downhill on the way back.

isabelaIMG_9702

Nearer town on the trail was a locals cemetery. It seemed like they were all new comers, I didn’t see any old markers.

That evening from the back of the boat we were entertained by hundreds of bombarding blue-footed boobies going after their evening meal.

isabelaIMG_9634

Not great focus, but here are the boobies just as they hit the water. The little fry didn’t have a chance.

This afternoon we did a snorkel at one of the only places we are allowed to go without a National Park guide. Here is an artist rendition of a penguin shooting by us underwater. These guys are bullet fast underwater, and hard to see much less photograph.

isabelaP2200072

Chris found this 10-12 inch open oyster. If you biggerrate by clicking on it you can see a striped 3-1/2 to 4 in fish on the lower lip.

And a gratuitous mangrove photo for our friend Save-the-Mangroves Will. You can see a heron center top hanging off the mangrove waiting for a fish to come by.

A little Isabela Wildlife

isabelaP2160055 These Galapagos penguins are hanging on the rocks just near where we are anchored. We call it Drycleaner Point. These little guys are similar to the tuxedo dressed penguins of the Antarctic, just without the extra layer of body fat insulation since they live at the Equator.

isabelaIMG_6912

There’s some good trails around Puerto Villamil for checking out the wildlife. Here’s a curlew, or maybe an Ibis. Our tropical Pacific bird book doesn’t cover the Galapagos so we have to make up most of the identifications.

isabelaIMG_6917

Definitely a Galapagos duck.

isabelaIMG_6918

This is the other end of the same duck, perhaps making identification easier,  while she’s working for her dinner.

isabelIMG_6929

Lots of Flamingos in the mangrove swamps.  Check the ugly duckling sitting on the log.

isabelaIMG_6935

This queen was getting all fluffed up.

isabelaIMG_6938

They’re not all colorful, but they make a good noise.

isabelaP2160058

Can’t forget the blue-footed boobies. They dive bomb for their fish breakfast every morning by the hundreds, just off the rocks by the boat .

isabelaIMG_6915

Another pond side feeder, a variety stilt.

Can you guess how to tell that this is a marine iguana instead of a land iguana?

If you are an astute reader and can instantly see the shape of this tortoise shell is different than the ones we blogged about on San Cristobol, then you are probably a distant relative of Darwin. The island of Isabel has 5 different sub-species of tortoise, all with slightly different shell shapes. Each sub-species lives around one of the island’s 5 volcanoes. These tortoises can live up to 150 years. Almost none of the wild hatched tortoises survive, due to the effects of introduced species such as ants, rats, goats, dogs, etc.  The eggs are taken from the wild and placed in breeding centers, where the babies get to grow to wild adolescents and are then released.

isabelaIMG_6953 Except for their shell, they really have no other protection mechanism from predators or man. Sailing ships stopped here over the centuries to stock up on the giant turtles, as they lived a long time in the holds of the ships without food or water – and gave up nice fresh meat.

isabelaP2160068

The sea lions on Isabela are not nearly as pushy as the ones on San Cristobol. This baby broke through our seal defenses and took a little nap on the swim step.
