Lake Atevine

Lake Atevine is a seasonal lake, located at the equator. The reason this lake can exist in the first place is because of a large asteroid which collided with the surface about 700 million years ago which holds the lake and acts as a heater by being more efficient to absorb the sunlight than the surrounding ice. During the impact the ice bended and gave way for the asteroid letting it (relatively) slowly lose speed and therefore did not cause a massive explosion-like event. The asteroid also were deformed during the entry making it thinner, wider and longer and naturally become a shallow bowl shape, where the lake is created during the late summers.
