The first Scottish colony on Mars, and was built in 1932. It used imported water from Earth to fill up a 24km wide crater, and imported grass to make a 50 square km grassland next to the new lake. Most scientists at the time thought it would never work. It used very new terraforming technology to make its own oxygen, and has been upgrading itself over the years. It is still (somehow) working to this very day.
In 1932, the Scottish needed a Mars colony to catch up with the English. They decided that they needed to outdo the British colony in every way. They decided to build an open air colony with a full lake next to it. This was an extremely ambitious project, and took forty-five years to even get the lake done.
