Darwin's Voyage on the Beagle
|
Yesterday’s
lecture was about Charles Darwin and the voyage of the Beagle. Charles studied
Botany at Cambridge and joined Captain Robert Fitzroy on the Beagle’s second
voyage around the world from Dec 1831 until 1836. This was a survey voyage, and
Charles, prone to sea-sickness, spent as much time as possible ashore, studying
the fossils, plants, and animals of the world. He spent 5 weeks in Galapagos
and noted the wide variety of beaks on the finches, leading him to believe that
there were separate species on the different islands. Today, we know that the
beaks of these finches actually can change year to year based on the food
sources. Thirty years after the voyage of the Beagle he published the Origin of
Species. He was hesitant to publish because he knew it would upset the
church teaching and science of the day, including his very religious wife.

Orsono Volcano

Puerto Montt was settled in 1853 by German settlers. It is considered the entry
to Patagonia. The town has doubled in population in the last 20 years since
Salmon Farming was introduced in 1980. Today, Chile is second to Norway in
Salmon exports. This is the Lake District of Chile with lots of rain, but no
snow. The salmon start in hatcheries, then are moved to the Lakes as
fingerlings, and finally to the sea. There are over 120 active volcanoes in
Chile. The most beautiful here is Osorno, 8700 feet, almost a perfect cone, but
it hasn’t erupted since 1863. Nearby is Calbuco volcano, 6670 feet, which
erupted in ash three times in April, 2015. The volcano eruptions caused large
evacuations, but little damage. But when the rains came after the outpouring of
ash, roofs collapsed, rivers were re-routed, and landslides occurred.
Everywhere we looked as we approached the Vincente Perex Rosales National Park,
there were large piles of ash along the side, same when we came to the river.
We took a 45 minute cruise on Lake Esmeralda the sun came out, and the view of
the volcanoes and mountains were magnificent.

Petrohue River
|
Then we took a short hike to the
Petrohue River to see the rapids come down the river. It was impressive. This
was the same river that I had rafted (a little further downstream) when we were
here 15 years ago. Then we went to
Puerto Varas, the city of roses, along the Lake Llanquiehue where we had a delicious lunch, including Pisca Sour, before a
little time to wander the town square.
