Contest #625: Ovnipuerto Cachi, northwest Argentina

In 2008, Werner Jaisal received a message from the captain of a UFO asking him to build a UFO landing pad with the words “If you build it, they will come.” Not quite the same as the famous saying from the book/movie Field of Dreams which is “If you build it, I will come,” but enough about baseball…

Following the plans given to him, Werner Jaisal built Ovnipuerto Cachi with piles of rocks into the pattern we now see.

Contest #624: the Trans Alaska Pipeline and Dalton Highway near Prudhoe Bay, Alaska, US

The Trans Alaska Pipeline runs over 1200 km south from Prudhoe Bay all the way to Valdez, Alaska. The Dalton Highway goes about 666 km to near Fairbanks.

They criss and cross each other and cross numerous rivers on the way, reaching an altitude of 1444 metres at Atigun Pass in the Brooks Range.

By 2010, the pipeline had shipped over 16 billion barrels of oil south. However, at this time it only transports a fraction of the maximum of about 2 million barrels of oil per day.

Contest #623: Malleco Viaduct, central Chile

The Malleco Viaduct in central Chile passes across the Malleco Valley, and when opened in 1890 was the highest railway bridge in the world.

Some claim it was designed by Gustavo Eiffel, designer of the Eiffel Tower in Paris. But he just proposed a design that was rejected in favour of a design by Aurelio Lastarria.

Contest #622: the Brooks Aqueduct, Brooks, Alberta, Canada

Built in 1914, the Brooks Aqueduct was to irrigate a large section of land near Brooks, Alberta. It was the largest concrete structure in existence at the time and crossed a lowland area. The Canadian Pacific Railway passed through the area and the Aqueduct passed under the railway with an inverted siphon.

The siphon is an inverted reinforced steel concrete pipe that operates on the Venturi Principle. It was built to a depth of 40 feet underneath the tracks and narrows in the middle to increase the pressure on the water passing through.
