Picture of the day Trou au Natron is a volcanic caldera in the Tibesti Massif in northern Chad. The volcano is extinct, and it is unknown when it last erupted. Trou au Natron is located just south-east of Toussidé, the westernmost volcano of the Tibesti Mountains. The caldera has an irregular diameter of approximately 6 to 8 kilometres (4 to 5 miles) and is up to 1,000 metres (3,300 ft) deep. Because of its irregular shape, it has been theorized that the caldera was formed as a result of multiple massive explosions, each of which deepened the enormous pit. Its exact period of formation is unconfirmed, although a Pleistocene formation has been suggested. Much of the surface of the caldera is lined with a white crust of carbonate salts such as sodium carbonate and natrolite, known as natron, leading to the caldera's name, literally 'hole of natron' in French. This crust is sometimes known as the Tibesti Soda Lake. Both the slopes and the floor of the caldera contain thick layers of fossilized aquatic gastropods and diatoms, indicating that it was once home to a deep lake. This satellite image of Trou au Natron was taken in 2008 from the International Space Station, at an altitude of around 352 kilometres (219 miles). The white crust can be seen at the bottom of the caldera.Photograph credit: NASA The size of Wikipedia As of 20 April 2025 at 04:37, UTC, there are 6,983,863 articles on the English Wikipedia.

Hello Sunborn

I made some edits to a page you had previously worked on. My comments about the recent round of edits to the List of Zeta Psi chapters is on the Talk page. If you have continuing interest and time, I'd welcome your review. You'd also be welcome to join the Fraternities and Sororities Project. If I read correctly your reasons for semi-retiring, I concur that edit wars and Deletionism has been a problem. For us, we police these articles within our area of interest, and have kept the Deletionists and other trolls at bay. We now monitor several thousand pages, and are actively improving them.

As a fellow engineer, I believe that you should undo removal of [[Category:Wikipedian engineers|Sunborn]]
