We
awake anchored in Urvina Bay. This is a
very pretty cove midway along Isabela Island’s western shore. Because of the heat, this morning’s
excursion starts early at 7:30 AM.
After going through the same breakfast drill of “there’s nothing for me
to eat,” we grab our cameras and snorkeling gear and head to the main deck
where people are lining up to board the pangas for the shore. It is just a short ride to our first “wet”
landing. This landing is on a sandy
beach crossed with turtle tracks and nest indentations where they have laid
their eggs. We cache our snorkel gear
and pick our way carefully through the maze of turtle nests up on to more solid
ground – but it isn’t. All of the land
around Urvina bay was formed only about fifty years ago when the sea floor was
volcanically uplifted. This volcanic
action has caused the top layers of the earth beneath us to be separated by air
spaces. So if you stamp your foot on
the ground, you hear a hollow thumping echo very similar to the floor echoes
you may hear when walking heavily through your house. Also because of the recent formation of this land, it is very
flat and lacks any significant sized trees.
Instead, it appears all to be scrub about 15 feet high.
As
we trudge through the hinterlands of the bay, we see many birds, including a
number of Darwin’s famous finches and one rare cuckoo. The first sign of larger animals is in the
form of iguana tracks and burrows. The
tracks are distinctive because of the stripe traced by the iguana’s long
trailing tail through its scrabbling footmarks. Their burrows are holes about 4 to 6 inches across dug into the
ground. We try looking into a hole to
get a feel for its depth but receive no reflection. Finally we come across some of their live occupants. One of the land iguanas is golden and the
other green. Both lie quietly back in
the underbrush, so clear views and pictures are hard to come by. But then we see the star attraction of the
islands, a giant tortoise, and in the wild!
(Most visitors to the Galápagos only see tortoises kept in “zoos” like
the Charles Darwin Research Center.)
This one is a juvenile come down from the slopes of the Alcedo volcano
that hovers in the background. The
largest collection of wild giant tortoises in the Galápagos make their home up
in the crater of this volcano that dominates central Isabela Island. The juveniles are more footloose and wander
more distantly. But to see the adults,
you must embark on a two to three day roundtrip trek up to the volcano’s
crater. Something to put away for our
next visit.
Our
guide Enrique (“Kiki”) also tells us about some of the vegetation that we
pass. Among the most prevalent is a
bush/tree that bears many bright yellow flowers. It is called a manzanillo or “poison apple” tree. The sap will irritate your skin, and the
fruit, though a favorite of the tortoises, is very bad for humans.
As
we return to the beach, we spy a flock of wild goats up on the hillside. These creatures are the bane of the
Galápagos ecosystem. Introduced by
sailors and settlers some years ago, they have steadily expanded their range,
denuding all vegetation as they go.
Their destructive habits are the biggest threat to the survival of the
Islands’ tortoises. A program has been
started to reduce their number, and in the ideal, to eliminate them
altogether. The plan is this. Wardens capture a few of the goats and put
radio transmitter collars on their necks.
These goats are then released back into the wild at scattered
locations. Because goats are herd
animals, these beacon goats will soon commune with others in a flock. After giving the released goats a few days
or weeks to meet up with their old buddies, hunters are sent out to home in on
the radio signals that now will hopefully mark a whole bunch of goats to be
liquidated. The theory is that the
hunters will pick off a good number of the goats before the gunfire causes the
rest of the herd to scatter. The hunters
then retreat for a few days and allow the herds to re-form. The hunters track them down again, pick off
a few more of them, and so on.
According to Kiki, the problem with this plan became apparent the first
time it was tried. The goats with the
radio transmitters were released, a bit of time passed and the herds were then
tracked. But when the hunters began
shooting at the herd, the first goat to go down was the one wearing the radio
collar. So the plan’s genius for cheap
repetition was foiled. After this faux
pas, all captured goats that were fitted with radio collars also had their
horns painted a bright color to warn off shots from the hunters. I hope it works.
Back
on the beach, we did some snorkeling along the rocks lining the sides of the
cove. It wasn’t too interesting. The water was murky and there were only a
few fish. The highlight was when a sea
lion arrived to check out the human bathing activity in the cove. The kids were entertained by the sea lion’s
curious expression as it cruised around, raising its whiskered face to inspect
these strange furless swimmers. Other
visual entertainment was provided by a very persistent pelican that put on a
great display of fishing. It would
repeatedly labor into the air, cruise over the bay, dive into the water, strain
the water out of its pouch, gulp down whatever was left and then start the
process all over again. It was tiring
just to watch. As noon approached, we
returned to the Santa Cruz.
It
was during the walking this morning that I realized that my tooth no longer
bothered me – and hadn’t done so for a least a day. Armed with this new piece of data, (i.e., that I didn’t have an
infected tooth), I was able finally to reconstruct why the irritation of two
days ago had occurred. On the drive to
Newark airport and early on the plane ride to South America, I had been chewing
a piece of gum. In my old age, I have
found that vigorous chewing of a stiff wad of gum flexes my teeth, stretches
the ligaments holding them in place and has caused me irritation in the past. But this irritation only becomes evident
some hours after the chewing has occurred.
But in my hypochondria to attribute the pain either to the worst reason
for my sore tooth (infection) or to the most esoteric (altitude), I had
forgotten the simplest – gum chewing. I
had no more troubles for the rest of the trip and my stash of antibiotics and
painkillers went unused. Hurray!
During
lunch, the Santa Cruz motored further down the western coast of Isabela to our
afternoon excursion location, Punta Moreno.
This excursion was to be broken up into two parts: a panga ride along the rocks and into a
tidal lagoon and a walk across a lava field to a salt pond where we might see
flamingos. Because the walk would cross
unstable and fissured shards of lava, it was not recommended for the older
passengers – who would receive a longer panga ride.
As
our panga approached the shoreline of Punta Moreno, we headed first for a rocky
point that was being beaten and sprayed relentlessly by the surf. On this point were scattered penguins, sea
lions, cormorants, blue footed boobies, marine iguanas and Sally Lightfoot
crabs, all lounging around completely interspersed with one another. There was no territoriality, no “this spot
is saved for my species,” just a mass of different animals sharing the same wet
location.
Perhaps
now is an opportune time to discuss photography. We have brought four types of cameras on this trip: (1) an old 35mm Pentax SLR equipped with its
standard f1.7 50mm lens and an f4 70-200mm zoom lens, both lenses manual focus;
(2) a small 2.1 megapixel Canon digital still camera with 2x optical zoom; (3)
a Sony Digital8 video camera with 20x optical zoom; and (4) a couple of
disposable 35mm underwater cameras. Not
only is this a bit of a load to carry on each shore excursion, but the juggling
act that must be done to keep all of these optical pieces in play (plus two
pairs of binoculars) leaves little opportunity for direct eyeball
sightseeing. It quickly became apparent
that each of these cameras has particular strengths and weaknesses.
In
a bouncing panga, the SLR is just too unwieldy, especially with the zoom
lens. This is partially the result of a
retrospectively unwise decision that I made concerning the type of film to
bring with us. Based on guidebook
recommendations that noted the fierce sun of the equator and the primitive
airport X-ray machines in South America (X-rays inspection is more likely to
fog high speed film than low speed film), I brought predominantly ASA 100
film. But given that a number of days were
overcast and I often wanted to use the f4 telephoto lens rather than the faster
f1.7 lens, this slow film caused the camera’s automatic shutter speed to drop
into the 1/30 to 1/60 of a second range.
Which is really too slow to get a sharp picture without the steadiest of
camera platforms – a panga not being one of them. Given that all of the X-ray machines in Quito seemed to be of the
same caliber that we see in the U.S. and my recurrent desire to use the
optically strongest camera we had, I could have kicked myself for not bringing
ASA 400 film. The increase in picture
sharpness due to the faster shutter speed would have far out-weighed any
increase in film grain.
But
there is no way to swap out my 100 ASA stash of 16 rolls for higher speed film,
and until the pictures are developed there is also no way to know how much the
unsteady camera platforms would degrade the pictures, so this is what we have
to work with. But as a result, I soon
determined that from a panga, the video camera was the instrument of
choice. The SLR would be used predominantly
on shore, and the digital still camera could be used for snapshots
anywhere. (All the photos that have
been attached to this journal come from the digital camera.)
After
cruising along the rocks, the panga entered a mangrove-surrounded tidal lagoon
where the water was calm. The driver
cut off the engine, and the panga coasted quietly. Soon we sighted several large sea turtles swimming through the
water, a school of spotted eagle rays and a few small sharks. Evidently, this lagoon is a well-known spot
for glimpsing this wildlife because we were soon joined by the panga carrying
Mom and a number of other passengers.
We were, thus, able to take pictures of one another from our separate
boats. After a few more minutes of
silent viewing, we motored out of the lagoon and to our landing point by the
lava field.
The
lava flow that we landed on lies between two of Isabela’s volcanoes, Sierra
Negra and Cerro Azul. This flow was
created by a relatively recent eruption – sometime about 300 to 400 years ago. Although this is within historic time for
the Islands, visitors were sufficiently infrequent and the records they kept
were sufficiently sparse, so no one knows the exact date. The lava here is a combination of what is
called pahoehoe or “ropey” lava and aa or “broken” lava. (The received worldwide glossary for lava
types comes from the Hawaiian language, where they are the acclaimed experts on
lava.)
We
then began a half mile hike over this lava flow to the salt pond. It was very much like walking over a field
of broken crockery. Continual
high-pitched squeaking and crunching of the surface underfoot. This field of broken lava is punctuated by
small patches of more solid ropey lava, but more ominously, by numerous
fissures with both sharp edges and a width adequate to swallow a small
boy. And of course our boys were taking
the hike like a playground obstacle course, not as a dangerous environment in
which 911 doesn’t exist and any help is two days away. Thus, they were blithely seeking cracks to
jump over, fragile lava points to stand on, etc. It was none too restful for their parents. But at least Jeffrey wisely chickened out
when dared by his brother to jump over one crevice that was about three feet
wide and at least ten feet deep. While
you might say that jumping three feet from a running start is nothing for a
small boy, you must remember that both the takeoff and landing “platforms” are
themselves broken lava shards so that the footing is uncertain. And even if your jump is of adequate distance
to land on the other side, if you do not successfully keep your footing, you
are in for some nasty cuts from a roll on the lacerating lava.
As
we reached the salt pond that was the goal of our hike, we are rewarded with
the sight of two flamingos feeding at its distant end – and they are of the
appropriate pink color. We spend about
fifteen minutes sitting on a lava bluff above the pond watching the flamingos
and bathing in the late afternoon light (it was about 5:30 PM). The light here is truly sensational. It is like the luminescent glow we receive
just prior to a summer thunderstorm when the sun’s rays seem caught between the
earth and the dark underside of the storm clouds. But here the effect is doubled.
We have both dark clouds overhead and dark lava below. So only the intermediate points like the
people, the pond and the vegetation around the pond are capable of reflecting
light. You want to keep such a scene in
a bottle forever.
We
then prepared to leave the pond to return to the ship. Time was growing short. At the equator, when it reaches 6 PM, the
sun drops precipitously below the horizon and there is very little twilight. But then a speck appeared in the sky beyond
the pond. As it grew bigger, I
recognized it as a flamingo in flight and pointed it out to the other
onlookers. Flamingos fly in almost a
straight horizontal plane. Their long
neck stretches straight out in front, and their legs trail horizontally behind
them. The bird glided circularly around
the lake and lost altitude. As it
reached the level of the water, its legs came down and began to windmill. The flamingo appears to run for ten or
twenty meters along the pond’s surface until it finally alights. We broke into spontaneous applause at its
performance. I believe even our guides
Pierre and Lola were awed by this display.
In the dying light, we walk quickly but carefully back to the shore,
content with another deep experience to file away.
Our
panga is the last to return to the ship.
On the way back, we see a flock of Audubon’s shearwaters floating in the
water. These little birds spend their
entire life at sea. It seems harsh, but
I guess they are used to it.
For
dinner, the chef made pizza for the several kids on the cruise. Normally, this is a sure-thing meal for our
kids, but Eric found something wrong with it, and didn’t eat any. They retired to our cabin along with two
other boys to watch the Harry Potter DVD.
After
dinner, I went up on deck for this evening’s stargazing. It is great. Rather than “holding” water as it does in the Northern
Hemisphere, the Big Dipper faces downwards to point to Polaris – which cannot
be seen below the horizon. Opposite the
Big Dipper and over the South Pole is the Southern Cross. Truly a magnificent constellation that I
have never before seen (you can’t see anything in the night sky from downtown
São Paulo). And unlike in the northern
hemisphere where you need to be an expert to locate the constellations of the
Zodiac, here on the equator they span the sky from east to west. These constellations start from the horizon
midway between the Southern Cross and the Big Dipper and march directly over
your head and down to the equator on the other side. Just beautiful – especially because the nearest artificial lights
are a hundred miles away.
So
ends another spectacular day.
