World’s Largest Rhythmic Spring

A rhythmic spring is a water spring from which the flow of water either varies or starts and stops entirely, over a fairly regular time-scale of minutes or hours. The “Intermittent Spring” located in Swift Creek canyon in Star Valley, near Afton, Wyoming is the largest rhythmic spring in the world. The theory is that as groundwater flows continuously into a cavern, it fills a narrow tube that leads out. As the cavern overflows it creates a siphoning effect and when that happens the hydraulic effect pulls the water out of that cavern and creates a river which runs for about 15 minutes. Eventually this siphon is broken once air reaches the pipe and it breaks off. Then the cavern fills again with water and it starts the process all over again.

The Infinite Bridge: A bridge that leads to nowhere

Circle shaped bridge located on Varna Beach on the outskirts of Aarhus in Denmark. Originally, The Infinite Bridge (Den Uendelige Bro) was displayed in relation with the Sculpture By The Sea event in 2015. The Municipality of Aarhus contributed to reconstructing the bridge as a permanent piece of art – and an infinitely beautiful pier. The Infinite Bridge has been created by architect Niels Povlsgaard and Johan Gjødes. The circle shaped, wooden construction spans from the surf and out into Aarhus Bay, and it is a popular excursion spot for locals as well as tourists.

Beautiful dancing mangrove trees in Sumba island, Indonesia

Mangroves at Walakiri Beach, Sumba Island, Indonesia. At sunset, the waters recede to reveal the roots of the dwarf mangrove trees. Each tree curves and “dances” in its own unique way, and the silhouettes look like dancers jiving at the horizon.

A tree growing out of a white salt island in the heart of the Dead Sea

Dead Sea is one of the world’s saltiest bodies of water – 9.6 times as salty as the ocean. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. A tree growing out of a white salt island in the heart of the Dead Sea isn’t something you’d expect to see The tree on this unique island off the shores of the Dead Sea was planted there by a local artist. The artist every day puts mud around its base to ensure that it gets all the nutrients needed to survive.

Nature’s bridge in Finland

Punkaharju is a harju and belongs to Finland’s national landscapes. The narrow ridge section is about seven kilometers long and was created during the Ice age when a glacier basically acted like a giant, uneven scraper on the landscape. Punkaharju became a popular tourist destination at the beginning of the 19th century by Sakari Topelius in his book Maamme and J.L. Runeberg in his poems.

The Great Blue Hole

The Great Blue Hole is a giant marine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll in Belize City. The hole is circular in shape, 318 m (1,043 ft) across and 124 m (407 ft) deep. The site was made famous by Jacques Cousteau, who declared it one of the top five scuba diving sites in the world. The Great Blue Hole is a popular spot among recreational scuba divers who are lured by the opportunity to dive in sometimes crystal-clear water and meet several species of fish, including midnight parrotfish, Caribbean reef shark, and other juvenile fish species.

Experimental Forestry in Japan results to amazing Tree ‘Crop Circles’ half a century later

Aerial photos reveal groups of Japanese cedar trees swelling toward the sky, creating two forest circles. According to a 1973 document from the Japanese Ministry of Agriculture, Forestry, and Fisheries, researchers had embarked on a project designed to examine tree spacing and its effect on growth. According to Japan’s Ministry of Agriculture, the height difference between the smallest trees at the center and the tallest trees on the outer ring was over 5 meters. Again, this implies that trees in less dense areas have more access to resources while trees in the center, have to compete for sunlight and water.  The research team is bringing the experiment to an end. The trees will be harvested unless they are preserved as a tourist attraction.
