Lost POSELENIE (Ancestors of The Humankind Odyssey)

Gone from the starting settlement, walked a bit through the swamp and came to the rock, went with him and decided to come back. And no. Can't find the settlement, about 1.5 hours looking for, walked for almost everything, but the settlements are not, the ability does not help that they work almost close. Climbed to the highest point of the map, not helping. Even no signs of the settlement can not see. Already cheats downloaded to somehow find, and they go even through the same places (the waterfall in the rock), pass through it as then, but why go out on the territory of the Savannah. How to get back to base?
