The Mexican Yucatan today is known as a place of jungles, ancient pyramid tourist sites, and warm beaches with tropical waters. However, centuries ago, it was also a thriving network of civilizations, from ancient small migratory tribes to entire networks of cities and trade from ocean to ocean. Geologically, the area is replete with gaps, dips, caverns, and caves (6,000 plus) as well, which makes the area that much more interesting for explorers. One particular feature is that of the cenote, or underground lake. Created by shelves of hard penetrating stone underneath soil, these caverns form from permeating rainwater that collects until it can finally drain to the oceans. The water is pure and clean, a great source of freshwater, and also a common trap that has captured many living creatures over time. The case of one particular “black hole” cenote has recently produced one of the earliest known samples of human beings in the Americas to date.
In 2007 a cartographer, Alberto Nava, was working on a larger project of tracking and mapping the Yucatan’s many underground caves and waterways. Near Tulum, Mexico, an ancient coastside ruins from Mayan times, Nava found a notably large pit, named El Hoyo Negro, going 100 feet deep. No one had fully explored it yet, so it was a prime location for Nava’s work.
The El Hoyo, the Black Hole of Death, is as dangerous now as it was thousands of years ago. Cave diving in general is dangerous due to the risk of being trapped, falling rock, unstable geological features and more, but people still do it to explore. Nava’s team was no exception.
Like most cenotes, access to El Hoyo requires some means to go straight down, whether by rope or ladder. After a 30-foot ladder path, divers then face cold waters that pull body heat out quickly and require body suits as well as proper diving safety equipment and extra air tanks. Most channels are entirely filled with water and there are no safety places to surface, so getting trapped is very possible in the dark if the lights go out.
After some extensive exploring, gingerly moving to avoid destruction of the environment, one of the tunnels opened to a huge cavern about the size of a basketball stadium. That’s were a big surprise was waiting and required them to go back, get more equipment and more air tanks, and do the exploration job safe and right.
Going in with the right equipment, the team found multiple sets of skeletons, many clearly from prehistoric times. Among the collection there was giant ground sloths, short-faced bears, a sabre-tooth cat, and the most valuable skeleton set, a human being.
The human skeleton was unique and magnificent for a number of reasons. First, when exposed in an environment, the body and bone tend to deteriorate quickly. Bone lasts the longest but, if left open to air, most forensic anthropologists will agree it begins to dry out, splinter and fall apart. In the Black Hole case, the skeleton was under water void of predators or scavengers. It was complete, pristine, and intact due to no air exposure.
Propped up on an arm as if in a laying position, the body was a huge find, but Nava’s team didn’t want to disturb what they knew they didn’t understand at the time. Instead, of moving anything, the team left the body intact for two years. A combined effort including expert teams from Canada and the U.S. came back repeatedly to run tests on the human skeleton as collected underwater. The results where shocking.
A number of theories exists as to how humans first arrived in the Americas, one being the Beringia theory, or land mass passage from eastern Siberia to Alaska and then southward. Many of the genetic tests run show a link between Asian populations and that of Native Americans and indigenous cultures. However, others have no such genetic linkage are completely unique.
The tests on the Black Hole body came back with amazing details. An age factor of 12,000 or 13,000 years old was the big one. Second, the body was that of a female, likely a 15-year-old teenager. Third, the body was very much homo sapien, a modern human being. Dubbed Naia by the teams, an ancient Greek name for water nymph, the skeleton takes the title as the oldest known recovered human being in the Americas.
The discovery is significant because humans in general are only known to have been in existence for the last 200,000 years, and in the Americas they didn’t appear until approximately 14,000-15,000 years ago. Given the date of the skeleton, Naia represents one of the earliest inhabitants in the Mexican region as well as the entire Western Hemisphere.
Phyiscally, Naia’s body did not have many of the same characteristics found in today’s American indigenous people. This was concluded by skull and skeleton measurements and comparison with forensic data from modern Native Americans. Yet the body did provide a treasure trove of details for analysis: a complete teeth set, almost all of her skeleton, intact bones, and many extremity parts normally missing due to time.
It is assumed that Naia fell into the Black Hole cenote which sealed her fate. Estimates put her fall at approximately a half-mile of descent, which easily would have killed her. Clearly, she was not the only victim; many larger creatures twice to five times her size had been trapped as well.
Other features determined found Naia had given birth, was much smaller than today’s similar teenager, and weighed no more than 110 pounds. Life was rough in her time; Naia had a mended broken arm among other injuries. Given her teeth and skull form, she would not have resembled today’s Native American. However, her DNA did trace to the same markers as Native Americans.
Once testing was complete, it was determined Naia and the other artifacts needed to be moved and protected. Unauthorized viewers and looters were coming and intruding, eventually destroying much of the site will ill-prepared swimming practices and equipment (bubbles can easily damage underwater stone formations). Fortunately, Nava’s team created a 3D map of the entire cave system, preserving its information for archaeologists to still study regardless of the damage done.

40 of the Worlds scariest bridges
Everyone has a fear of something and fear of bridges is not less a fear. There are some bridges in the world which are very scary and even dangerous to cross over. These bridges in different parts of the world have set records as the most hazardous and the scariest bridges in the world. For people with fear of bridges; gephyrophobia, these are bridges you definitely want to stay away from but for the fun-loving daring people then this is an adventure you may want to venture into.
The Royal Gorge Bridge, Colorado;
This bridge found in the USA was made in 1929. During the time of its building, it did not have any wind cables which makes it very interesting. It was not until 1979 when wind cables were added to the bridge. It is in the highest suspension point in the United States which is similar to its historic significance, crossing 955 feet high over the Arkansas river. The Royal Gorge Bridge has held record as the tallest bridge up until 2001 when the Liuguanghe Bridge of China surpassed it. It spins 1260 feet over a rocky canyon.
The Invention of Pinball
Pinball is an arcade game where you score points by manipulating balls around on an inclined play field with flippers. The goal is to hit various targets without losing the ball through the drain at the bottom. Most modern pinball machines are themed—they tell a story and players complete objectives to finish the story. Pinball has been around for decades. But where did it come from?
Origins Date to 1871
In 871, the British inventor Montegue Redgrave received a patent for his game, “Improvements in Bagatelle”. Bagatelle was a game that used a table and balls, but Redgrave received the patent in order to make changes to the original game. He added a coiled spring, a plunger, inclined the playing field and made it smaller, and replaced the larger balls with marbles—all of which are features of pinball.
Mass Production 1930s
It wasn’t until the 1930s that pinball machines appeared in mass. In 1930 and 1931, these games were countertop machines, rather than freestanding with legs as we know them today. Manufacturers began adding legs in 1932.
The first countertop pinball machine was called “Bingo”, and was produced by the Bingo Novelty Company. This was the first pinball machine manufactured by D. Gottlieb & Company. Next, the company released “Baffle Ball”, another countertop mechanical game. In 1935, they released the same game in an electro-mechanical standing version. It even had a payout.
In 1931, another countertop pinball machine was released called “Bally Hoo”. It included optional legs and was the first coin-operated pinball machine in existence. It was developed by Raymond Maloney, the founder of Bally Corporation.
Origins of the Name
The game was not actually called “pinball” until 1936. The first pinball games did not have flippers, the balls were instead directed by static nails, or pins, which gave the game its name.
One of the most popular pinball machines in history is “Advance”. The tilt mechanism was invented in 1934 because players had been physically lifting the machines to shake the ball around. Tilt fixed this problem. The tilt mechanism was first used in “Advance” the pinball game made by Harry Williams.
In 1933, battery-operated pinball machines were introduced. They were first made by Harry Williams; by 1934, electric machines showed up which allowed them to offer plenty of extra features, like new sounds and lights. In 1937, the bumpers were added in a game simply called “Bumper” by Bally Hoo. Flippers were then added in 1947, in a game called “Humpty Dumpty”. Flippers were invented by Harry Mabs and incorporated into the D. Gottlieb & Company game. It used six flippers, three per side.
In the 1950s, pinball machines got flashier—they incorporated lights behind a glass scoreboard which helped highlight the scores and added two player options. In 1963, multiple balls were introduced; designed by Steve Kordek and first used in the game, “Beat the Clock”. He is also the one that moved the flippers to the bottom of the game.
Ever Changing Pinball
Pinball has continued to change with the times. Digital scoring was introduced in 1966, and 1975, the first solid-state electronic pinball machine was released. Later, in 1998, pinball machines incorporated video screens, and today, players can play pinball online.
