Beginning: Marking Your Map

At first it's a bit hard to get around in Ark Survival.  Later on you'll get a GPS but in the beginning all you have is a map.  You make the map as you go along so only places you've been will show up.

The Obelisks

Ark has 3 giant obelisks in the sky (red, blue and green) whose purpose isn't entirely understood but are clearly seen from most points on the island.  Generally speaking the Red Obelisk is North West, The Green Obelisk is South West and the Blue Obelisk is South East.  On a clock dial, the Blue Obelisk is 4:00, the Green Obelisk is 7:00 and the Red Obelisk is 10:00.

When navigating around the map remember that the Sun and Moon rise in the East and set in the West, just like in the real world.  Between that and the three towers you should be able to find your way around.  The towers show up best at night.

I changed the Obelisk to "tower" because Obelisk Wouldn't Fit.

When you're done it should look something like this:
