One of Goa’s least visited but most fascinating sights is deep in the countryside at Usgalimal: a series of prehistoric petroglyphs (rock art), carved into the laterite-stone ground on the banks of the Kushavati River, and depicting various scenes including bulls, deer and antelope, a dancing woman, a peacock and ‘triskelions’ – a series of concentric circles thought by some archaeologists to have been a primitive means of measuring time.
These underfoot carvings are thought to be the work of one of Goa’s earliest tribes, the Kush, and were only discovered by archaeologists in 1993, after being alerted to their existence by locals. The images are thought to have been created some 20,000 to 30,000 years ago, making them an important, if entirely unexploited, prehistoric site. In order for you to make out the carvings better, you’ll likely have a helping hand from a local, who sits patiently at the site waiting to drizzle water from a plastic bottle into the grooves; he appreciates a tip for his efforts.
To get here, continue past Rivona for about 6km and keep an eye out for the circular green-and-red Archaeological Survey of India signs. An unsealed road off to the right of the main road leads 1.5km down to the river bank and carvings.
