Also recall, Earth has the moon which is considered special, the current paradigm has a Mars size planet hitting Earth, donating much of its iron core and forming out of the debris, I have not seen much discussion on it but would this not increase the density of Earth compared to Mars and Venus?

Tim I am not sure I can see the lakes, I can see two ice streams that appear to be falling into a gorge, with tarn like terminations. Is that them?
