Andrea Lorenzo (Lawrence) Grassi is honoured with a plaque at the lakes that bear his name in Canmore, Alberta, 🇨🇦. The story of this impoverished immigrant who overcame adversity in a new country and left his mark as a mountaineer and trail builder is told in this wonderful book.

July 30, 1869, the world’s first oil tanker named "Charles" departs from the US headed for Europe with a bulk capacity of 7000 barrels. Due to design flaws it was quickly replaced, like by the "Zoroaster" in 1878 🚢🛢️

The 15th-century Holstentor in Lübeck tilts because it was built on marshy compressible ground. It got so bad that the city almost demolished it in the mid-1800s, but its citizens voted to restore it instead. #geotechnical en.wikipedia.org/wiki/Holsten...

On April 26, 1908, in the early morning hours, a landslide hit the community of Notre-Dame-de-la-Salette, Quebec. The disaster killed almost three dozen people and destroyed much of the village. This is the story. 📸 Collection Jean Bastien 🧵 1/6

Several men in dark clothing and hats stand among the wreckage, examining the damage. One man stands near a large tilted section of wall in the foreground. In the background, partially collapsed structures remain, with a low ridge or hillside beyond.
