A day to celebrate curling, one of the chilliest and coolest of sports where athletes compete in a grown-up form of shove ha’penny. But did you know that curling stones come from stone quarried in one of only two places? They need very specific low quartz composition so they have low water absorbency. Well, now you do so grab your broom and start brushing.

Original Prompt (ChatGPT)

Curling stones are made from three types of quartz-free granite: Blue Hone, Ailsa Craig Common Green (both found on Ailsa Craig island), and Trefor, which can be found in the Trefor quarry of Wales. Please create a map that shows the location of these two quarries, and adorn the rest of the map with interesting facts about curling stones, and the sport of curling.
