10 Natural Phenomena

Whenever I have a few minutes in my schedule, I like to fill it with something interesting; if I’m eating lunch, I’m probably watching a documentary or a video about a particular topic. So I thought I’d toss together a shortlist of natural phenomena that are out there somewhere on our unique and diverse planet. Just click on the links below to learn more – the links will lead you to either a YouTube video or an article. So, here ‘goes!

  1. The Sahara Eye: Also known as the Richat Structure, it is a fascinating geological structure that’s best seen from lower orbit (located at 21.1269° N, 11.4016° W). Because of its concentric circular formations, there have been many claims that it was the fictional Atlantis of Plato’s writings. While the reasoning the supporters of that theory are interesting to me as a novelist, the scientific explanation is fairly straight forward.
  2. Spotted Lake, Canada: This lake has no run-off, which means that water flowing into the lake only leaves through evaporation. Divots in the lake have grown into spotted pools which attract various minerals as snow melt-water enters the lake. The Native tribes used these pools as therapy for physical ailments in a time before modern medicine, just like people in 18th century England went to Bath to drink and bathe in the mineral waters there. On Google Earth, its coordinates are 49°04’40.86″N 119°34’03.01″W; if you use the historical toggle, you’ll see the individual pools more clearly.
  3. Floating Eye Island, Argentina: This is a relatively new discovery from 2016, located at 34°15’07.8″S 58°49’47.4″W. It was discovered by Argentinian film director Sergio Neuspillerm, who was looking for a location to film a horror film and came across the Google map image of this unusual lake; because of his bent toward the purpose of this place, most “reports” have leaned toward the paranormal, and it was difficult to find a serious scientific report on the phenomenon. The actual interpretation is probably simply a combination of geology, botany and hydrodynamics: The lake produces methane gas, and if the floating island of debris and grasses growing atop the fertile strata get pushed around by methane bubbles rising, it will naturally knock off the rough edges of the floating patch and the land it bumps into, creating a circular “island”.
  4. Ice Discs: Similar to the Eye, these rotating discs of ice form in freezing water which is moving slowly; they usually form in eddy currents, where the accelerating water creates the effect called “rotation shear”, breaking off a chunk of ice and twisting it around; the process grinds off the rough edges, leaving a round disc of rotating ice. This disc grows as it cools the water around it and attracts more ice into its vortex.
  5. Sailing Stones, Death Valley, California: For years, people have observed the evidence of large boulders sliding across the surface of Racetrack Playa in Death Valley National Park. The explanation may be relatively simple, but sometimes people just like a mystery.
  6. Fairy Rings/Pixie Rings: These are caused by the processes of the mycelium of fungi, as it spreads outward in a circle while looking for nutrients. Before scientific understanding came along, of course, these were thought to be portals to the magical realms of pixies or fairies and were convenient scapegoats for anything bad happening in a nearby town or village.
  7. Since we’re on the topic of circles, what about the Namibian Fairy Circles? There are conflicting hypotheses about their origins, but the most recent study has discovered that beneath the bare circular patches of earth, distributed evenly over some 1100 miles of the Namib Desert, are colonies of termites. They eat the roots of the plants growing above their territory, removing the competition for the limited rainfall and allowing the water to go directly into the soil above their colony. It’s a complex ecosystem, but scientists are slowly beginning to understand it. In the meantime, the locals just call them the “footprints of the gods”.
  8. Blood Falls, Antarctica: A waterfall in Antarctica flows blood red, caused by the iron-rich waters hitting oxygen and turning to rust. The symbiosis of microbes living in that subterranean water source is the stuff good science fiction is made of.
  9. The Everlasting Storm: Catatumbo Lightning Storm, Venezuela: This lightning storm occurs during 140-160 nights per year, and lightning flashes up to 280 times per hour. Located over the mouth of the Catatumbo River as it empties into Lake Maracaibo, it has become so famous and so persistent that it is even featured in the flag and coat of arms of Zulia, the state which contains the lake, and is mentioned in the national anthem of Venezuela.
  10. Red Crab Migration, Christmas Island: Christmas Island is an Australian external territory in the Indian Ocean, and on this 135 sq km (52 sq mi) patch live literally millions of red land crabs, found only on this island. To spawn, the females make their way down to the beach at high tide to release their eggs into the ocean – at the risk of drowning, as they are not aquatic. The eggs will hatch, and the tiny crabs will eventually return to the island. During this mass migration, the island slows down and makes way for the red river flowing over its streets, stairs, and anything else between the crabs and their goal.
