The Galapagos Islands of Fire The Galapagos Islands teem with wildlife, above and below the water. Even the rocks are alive and constantly threatening to erupt as volcanoes vent their fury in this spectacular and historic place.

CRATE COLLAPSE Our motor yacht, Letty, lay off Fernandina In June, 1968, the caldera of Fernandina changed Island in the Western Galapagos, a place where dramatically when it’s fl oor, a block two the islands are bathed in the colder, nutrient-rich kilometres round, fell by 350 metres over nine waters of the Cromwell Current. The captain, days. The caldera was clouded in choking dust 8 and the crater lake disappeared. Some 2000 white-cheeked pintail ducks and land iguanas disappeared, too. Fernandina is still the most volcanically active island in the archipelago, with a dome-shaped cone that rises to almost 1500 metres. Its caldera is now 900 metres deep and six kilometres round. The Galapagos archipelago consists of thirteen major and six minor islands, with 49 smaller rock formations, all spread over 27,000 square kilometres. These equatorial volcanic islands erupted above the Pacifi c Ocean 950km west of Ecuador. They fi rst broke through the sea fl oor 7- 9 million years ago, and still show volcanic activity – seven volcanoes have erupted in the past 15 years alone. The Galapagos Islands sit on top of the Nazca Plate, close to the junction with the Cocos Ridge. The plates shift along the Galapagos Rift and the East Pacifi c Rise, which is making the islands move south-eastward at more than seven cm per year. The eastern islands are older than those in the west. Fernandina and Isabela, are the youngest – less than one million years old. We stepped ashore at Punta Espinosa, which means Spiny Point in Spanish. A lava/sand promontory, this place is surrounded by six volcanoes on Isabela Island, which lies across the Bolivar Channel. Stepping ashore onto the black lava from our panga – the local name for a small dinghy – Sally Lightfoot crabs scuttled on the green algae in the tidal zone. A pile of marine iguanas lay sunning themselves on the solidifi ed lava. As their body temperatures increased, they made their way to the ocean to feed on green algae, above and below water level. Further along, a huge whale skeleton lay on some sand and an inlet yielded endemic fl ightless cormorants. Here we enjoyed the cormorants fl apping their short wings. Sally Lightfoot crabs and marine iguanas lay all around. Sea lions were playing in the shallows. Distant views of volcanoes made for a splendid vista. Our natural history guides, Harry Jimenez (alias Loco Harry) and Jose Luis Castillo (alias Pepe) were a wealth of information, making the fi eld trips most enjoyable. The islands’ climate is greatly determined by the ocean currents. In the cooler dry season – July to December – the Humboldt Current keeps the islands much cooler than you would expect in an equatorial region. During the warmer, wet season 10 – January to June – there’s actually minimal rain on the coasts. DOLPHIN ENCOUNTERS The colder waters of Fernandina and Isabela Island are great for dolphin and whale watching – striped, common and spinner dolphins and pilot whales abound. Nowhere have I had such amazing encounters with dolphins as in the Galapagos. There must have been 70 dolphins, some of which congregated around the bow of our boat. Jumping into the ocean, I cleared the bubbles in my mask to see dolphins and a 5-foot Galapagos shark – so sharks do swim with dolphins. Dolphins were zooming in to see us from all around, often in pairs, peeling off when only two metres away. of sea lions and hundreds of Pacifi c creole fi sh, The sheer experience of being in the ocean with until we reached a point where two currents so many dolphins around checking us out was one collided.

Whenever there was a nip, the shark would give a good fl ick of its tail. The fi sh life in the Galapagos is fascinating and many of the fi sh look like overgrown versions of exotic and colourful African cichlids (ornamental aquarium fi sh to the uninitiated), with long fi lamentous fi ns. Even the giant damselfi sh look like our one spot chromis, but on a gargantuan scale. Some of the more remarkable species were the Pacifi c creole fi sh– looks like a fusilier; the Mexican hogfi sh – hump-headed with long, streaming fi ns; the guinea fowl puffer – yellow puffer fi sh and Galapagos garden eels– named ‘Anguila Jardin de Galapagos’ in Spanish. The marine iguanas on Espanola Island – called Christmas iguanas – are also vibrant, with spashes of pink and green. Each island has something different to offer. On Bartolome Island, we took the summit At Genovesa Island, we anchored in Darwin Bay, trail past splatter cones to an awesome lookout, an ancient caldera.
