Endorheic lakes and basins retain water and allow no outflow, just evaporation. If the water sneaks out underground, it is probably cryptorheic like Devil's Lake, Wisconsin.

Wiki - GDAL
An essential building block in GIS work today is the open source Geospatial Data Abstraction Library (GDAL). But, it is worth noting, that most of us don't realize that we are using it within the many other geospatial apps in our daily life and worklife. As the entry explains, it is embedded in the software that the GIS word relies on, including QGIS, R, ArcGIS, ERDAS, ENVI, MapServer and GRASS.

Wiki - Amiable Child Memorial
New York City has so many hidden features. Consider the Amiable Child Memorial that is dedicated to a bot that fell off a high bluff on the Hudson River in 1797. Not only is he remembered with a memorial, but also with a street named after him. Wikipedia tells the story.
This is a full article for what could otherwise be a long-forgotten incident. How many of these are there in NYC?

Wiki - Disruptive innovation
When a new idea or product displaces an entire previous category, we might call that a Disruptive Innovation. Some of these disruptions change entire markets. Think of how the smartphone has not only replaced the Palm Pilot and the landline, but maybe also the movie theater.
This is a rich and lengthy entry. I am especially appreciative of the section in which the editors have created an extensive table of examples and categories of disruptive innovations. The Examples are robust and fascinating - each with its own Wikipedia entry. The "See Also" list at the end is remarkable. Many of these topics have direct applications to the ongoing innovation and diffusion of GIS. The often misused Killer Apps, Hype Cycles, and the nearly forgotten Blue Ocean Strategy.

The study of bird's eggs is called Oology. The article describes the underground activities of egging, and mentions Colin Watson who was arrested and convicted repeatedly until he died falling from a tree while egging. It also mentions the secret society of eggers, the Jourdain Society, which was raided by the police.

Wiki - Taï National Park
Taï National Park in the Ivory Coast. The fauna list is extensive, with three different types of pangolin. Still, the threatened species are amazing: "Five mammal species of the Taï National Park are on the Red List of Threatened Species: pygmy hippopotamus, olive colobus monkeys, leopards, chimpanzees, and Jentink's duiker."

Wiki - Living root bridge
Trees are amazing. Making a bridge out tree parts doesn't sound exceptional until you see this version where the tree parts are still alive: Living Root Bridge. One of the examples is the Rangthylliang 1 root bridge which is over 50 meters long. The See Also list includes the equally interesting Baubotanik and Fab Tree Hab.

Wiki - Buridan's ass
The 14th century philosopher, Jean Buridan, grappled with free will and indecision. Later philosophers satirized his approach with Buridan's ass but it also is used as an understandable illustration of the concept. Its broader application can be seen in places like this piece, "US Climate Policy Caught Between Two Worlds — Are We Smarter Than Buridan’s Ass?"

Cape Verde recently got some attention. One small piece of that small country is Fogo, the volcanic island. We have learned to look closer at little places, right?

Wiki - Fogo Island, Newfoundland
For such a small and difficult to reach island, Fogo Island has a pretty lengthy entry. You may have seen it on the 1606 Bertius map of Newfoundland or on Season 2 of Severence. The histories include Marconi and the Treaty of Utrecht.

According to Wikipedia, Samuel Seymour held a couple of interesting distinctions:

That time that an insulation company drove a block of ice from Norway to the Equator. In Africa they met with Albert Schweitzer. Sometimes a publicity stunt is more than just that.

Harrowing story of a munitions plant explosion in Sayreville in 1918. In the 1990s, some shells were found near an elementary school and the resulting search found another 5,000 unexploded shells. more than 100 years later, the local high school is still called...the Bombers.

Ancient Aquiry
Nearly 2,000 years ago, the ancient city of Aquiry was very big. A new paper in Nature says that LiDAR has helped them identify 20,000 earthworks in the city. Seems like a lot.

Wiki - Landlocked countries
Wikipedia has a lengthy entry on landlocked countries. It includes basic "records" like largest (Kazakhstan) and most populous (Ethiopia). Less basic, like the fact that Kyrgyzstan is the farthest landlocked country from any ocean. And a little odd was a list of countries that are landlocked by exactly two other countries.
But the truly unexpected section was about "double-landlocked" countries, which are countries surrounded by landlocked countries. In all the world, there are only two of these exist: Liechtenstein and Uzbekistan.

August quote
I should post this every year...
"When the first of August came round, the Professor realized he had pleasantly trifled away nearly two months at a task which should have taken little more than a week."
-Willa Cather (from The Professor's House, 1925)
