PRACHUAP KHIRI KHAN, THAILAND (AFP) – An antelope, a lonely figure, a family linking arms – Kanniga Premjai shines her flashlight across a cave to reveal long-hidden paintings, a stunning discovery for Thailand’s scrappy team of archaeologists.
For months, Kanniga and her small team have combed Sam Roi Yot National Park, about four hours southwest of Bangkok, following a ranger wielding a machete as he slashes a path through thorny vegetation.
They had searched about 40 caves – with no luck – before they stumbled on a cavern located a steep climb through rocky cliff terrain.
“I screamed when we found the paintings,” she told AFP, pointing out clusters of rust-coloured figures that look like they are holding hands.
The dark walls initially shrouded the etchings, but careful examination and the use of a mobile application – which helps researchers enhance rock art – exposed the drawings.
“They are pre-historic and they’re about 2-3,000-years-old,” Kanniga said.
Thailand has unearthed ancient temples and cities, such as the ruins in the historic former capital of Ayutthaya and northern Chiang Mai – which attract domestic and foreign tourists.
But the search for cave drawings is more challenging for Thailand’s understaffed Department of Fine Arts, often because of the arduous trekking required.
“A lot of their primary work is just preserving what is already found… and that already takes up a lot of time,” said Noel Hidalgo Tan, an expert with Southeast Asia’s regional centre for archaeology and fine arts.
“There’s a lot of places in Thailand that are still unexplored.”
Locals often venture into the caves to collect guano – or bat feces used as fertiliser – but might not notice the wall art, which is why Kanniga’s mission is “to search every cave and cliff in the park”.
“We don’t know what we’ll stumble upon,” the 40-year-old archaeologist said, as she ducked into the cave’s inner chambers.
While they are not Thailand’s oldest – that title belongs to markings believed to be between 5-11,000-years-old found in the north – the “Clay Cave” supports Kanniga’s hypothesis that the Sam Roi Yot area was once home for pre-historic people.
Cave exploration is Kanniga’s passion, but this year is the first in her nearly two-decade career that she is able to devote time and resources to it.
She is one of three archaeologists overseeing six provinces in the Ratchaburi Fine Arts Department and previously spent time assessing historical sites to determine age and provenance.
“Foreign archaeologists usually specialise in one thing, but in Thailand we need to do a bit of everything,” she said.
The discovery of paintings in 2016 by authorities doing a cursory sweep of Sam Roi Yot’s perimeter prompted Kanniga to push for further research in the park’s unmapped grounds.
Today, the national park is popular with domestic tourists visiting nearby beaches and avid birdwatchers observing the wetlands.
The evidence suggests that hunter-gatherers lived in the area some 3,000 years ago, said Tan, a senior specialist on cave and rock art in the region.
“They would be moving camp-to-camp, so they would have a camp up in the mountains,” he said, adding that the shoreline of the Gulf of Thailand would have been further inland.
