Maps of our visit to Iceberg Glacier beginning from Cape Rapier, the Pacific Ocean
Here are a series of maps to aid your understanding of this series of blogs, starting with sunrise off Cape Rapier and ending with my next blog, the approach to Tempanos Fjord and the Iceberg Glacier.
The ship turned and the glacier, 500+ feet high, 0.7 mile wide, came into view on port.
At 5:09 PM (daylight savings time for Chile) the Regatta turned to starboard to navigate around a headland of Farquhar Island. Iceberg Glacier came into view from our port side stateroom terrace. I was set up with the Canon 300 mm variable lens set to 120 mm (1/500 second, F11, ISO500), tripod mounted, to capture the ice from 5 miles distance. The location is marked on the above GoogleEarth view. The red line leading in is our course. On the right, the white line is the boundary between Chilean regions Aisen and Magellan.
Visible is the .75 glacier front, 500+ feet above the head of Tempanos Fjord. On the GoogleEarth view the front is marked with a red line. Yes, more than 500 feet above the water. In mid-view there are two rocks in the water. Behind them, under the glacier, is a rock face. That rock is 100+ feet tall.
Twenty seven (27) minutes later I used a handheld Sony with variable lens set to 200 mm (1/500 second, F13, ISO800) to capture this image of the ship bridge superimposed on the glacier.
All you see is part of the Bernardo O’Higgins National Park. Named for a founding father of Chile, the country’s first head of state, the park covers 13,614 square miles.
Emerald Water, colored by glacial minerals
Glacial meltwater from Lake Todos los Santos (All Saints Lake) forms Petrohué River and, where the river flows over lava from the Orsorno Volcano, Petrohué Falls. This set of photographs features the emerald color the river originating from glacial minerals.
A strangeness of these photographs is this is the middle of February, Chilean summertime.
Another strangeness, not readily apparent, is the effect of the Coriolis force. Here in the Northern Hemisphere water (any moving mass, really) moving perpendicular to the rotating surface of the earth (a property of water is the surface follows the contour of the solid surface over which it flows) will tend to flow in a clockwise direction. Crossing the equator, in the Southern Hemisphere the tendency reverses, tending to flow to the left, counter-clockwise. With some imagination the effect of the Coriolis force can be seen in the following photograph.
