Discovery, Exploration
The approximate date when humans began expanding throughout the entirety of the Snow Rock Isles.
Around this year, humans likely invented their first boats. The first rafts could manage to travel over 10 miles without sinking. Humans managed to spread to every island. Finding land with higher soil content allowed them to move to agricultural subsistence, as unsuccessful as they likely were initially. Islands with grass were home to viable livestock. This variation in the human diet, beyond just fish, helped the human population grow.
