Back in 2014, I was hiking through Alligator Falls in Queensland, AU with a friend. We probably bit off a bit more than we could chew and started an 18km hike at 2pm. When we were making our way back, we were lucky the moon was out and bright. We were afraid we might be lost or off trail, but luckily we saw and recognized this Rock Totem:

It kept us on the path and we thankfully made it back out to the car.
