What they left is not a hunting scene or a herd of animals but geometry — lines, grids and repeating shapes worked into a cliff face on the southern edge of the Sakon Nakhon basin. Nobody has deciphered them. They were made long before anyone in this part of Thailand wrote anything down, by people whose language and names are gone, and the rock has carried them through something like a hundred generations of monsoon.

Phu Pha Yon National Park: The Forest Behind the Rock

Barking deer and sambar move through it...

Entry runs twenty baht for a Thai adult and a hundred for a foreign one, with small charges for a motorbike or a car. There is a campsite, gear for rent, a shop and a place...
