What is Nauwalabila I?
Nauwalabila I is a rock shelter archaeological site in Northern Territory, Australia. It is located on the southern margin of Deaf Adder Gorge in Kakadu National Park.
Archaeological evidence suggests that it is among the oldest Aboriginal sites on the continent, with an estimated age of more than 50,000 years. Archaeologists have found layers of charcoal and ash, stone tools and spear points, remains of food, and ochre.
The remains at Nauwalabila I offer vital clues about early Aboriginal culture and provide an important record of human interaction with the environment over tens of thousands of years.

Where is Nauwalabila I located?
Nauwalabila I is a rock shelter archaeological site located on the southern margin of Deaf Adder Gorge in Kakadu National Park, Northern Territory, Australia. It is considered among the oldest Aboriginal sites on the continent, with evidence suggesting human occupation dating back more than 50,000 years. The shelter is formed by a large sloping block of sandstone. Archeological findings include layers of charcoal and ash, stone tools, spear points, animal bones, shells, and ochre, a naturally occurring clay rock used as a pigment in rock art and ceremonial decoration.

Why is Nauwalabila I important for archaeologists?
Nauwalabila I is an important archaeological site because it potentially holds evidence of early Aboriginal culture dating back more than 50,000 years. Located in Kakadu National Park, this rock shelter contains layers of charcoal, stone tools, spear points, animal bones, shells, and ochre, which is a vital painting material for Aboriginal people. The discovery of ochre and worn sandstone slabs suggests its use as a pigment for rock art and body decoration. While radiocarbon dating proved unsuccessful, optically stimulated luminescence (OSL) indicates that the oldest findings might be 53,000 to 60,000 years old. The site provides insights into early human interaction with the environment and the tradition of using ochre in ancient art.

What types of artifacts have been found at Nauwalabila I?
At Nauwalabila I, a rock shelter in Northern Territory, Australia, archeologists have found an array of artifacts that suggest the site is among the oldest Aboriginal sites on the continent.
Discoveries include layers of charcoal and ash, stone tools, spear points, and remains of food, such as animal bones and shells. Also uncovered was ochre, a naturally occurring clay rock that was an important painting material for Aboriginal people. Slabs of sandstone show wear from grinding ochre into powder for use as a pigment in rock art and ceremonial body decoration. Faded paintings are also on the walls of the shelter.

How old are the findings from Nauwalabila I, and how do scientists determine their age?
The Nauwalabila I rock shelter in Northern Territory, Australia, is estimated to be more than 50,000 years old, ranking it among the oldest Aboriginal sites on the continent.
Archaeologists use optically stimulated luminescence (OSL) to estimate the age of the site. OSL measures the last time sand was exposed to sunlight. Radiocarbon dating attempts have been unsuccessful on the deepest findings at Nauwalabila I because the limit of carbon-14 dating is generally about 50,000 to 55,000 years ago.

What does Nauwalabila I reveal about the history of humans in Australia?
Nauwalabila I, a rock shelter in Northern Territory, Australia, stands as one of the oldest Aboriginal sites, potentially dating back over 50,000 years.
Archaeological finds, including charcoal, ash, stone tools, spear points, animal bones, shells, and ochre, reveal insights into early Aboriginal culture. The ochre, used as paint in ancient artistic images and ceremonial body decoration, highlights a long-standing artistic tradition.
The site's age supports the theory of human colonization during the Pleistocene ice age via the Sahul Shelf. However, dating remains contested due to termite activity potentially disrupting artifact layers. Despite debates, Nauwalabila I offers crucial records of human-environment interaction spanning tens of thousands of years.

Nauwalabila I, rock shelter archaeological site in the Northern Territory, Australia, that archaeological evidence suggests is among the oldest Aboriginal sites on the continent, with an estimated age of more than 50,000 years. Nauwalabila I is located on the southern margin of Deaf Adder Gorge in Kakadu National Park.
The Nauwalabila I shelter is formed by a large sloping block of sandstone that fell from the nearby escarpment. Archaeologists found layers of charcoal and ash on the floor of the shelter, which are believed to be evidence of campfire use. Stone tools and spear points, along with the remains of food such as animal bones and shells, were also uncovered, as was ochre, a naturally occurring clay rock that was one of the most important painting materials used traditionally by Aboriginal people. Far beneath the surface in the rock shelter at Nauwalabila I, there was evidence of many colours of ochre and slabs of sandstone that showed signs of wear from grinding. The proximity of these findings likely indicates that the ochre was ground into a powder and used as a pigment in rock art and ceremonial body decoration. There are also faded paintings on the walls of the shelter. Attempts to use radiocarbon to date the deepest of these findings failed (the limit of carbon-14 dating is generally held to be about 50,000 to 55,000 years ago), but the use of optically stimulated luminescence (OSL)—which measures the last time the sand in question was exposed to sunlight—led some archaeologists to believe that the oldest findings dated from 53,000 to 60,000 years ago.
The supposition that both Nauwalabila I and Madjedbebe—another rock shelter archaeological site, located about 45 miles (70 km) north of Nauwalabila I—were inhabited more than 50,000 years ago coincides with the theory that the original human colonization of Australia occurred during a Pleistocene ice age when low sea levels exposed the Sahul Shelf and would have allowed early humans to cross from Papua New Guinea to Australia almost entirely by land. The notion that this might have occurred more than 60,000 years ago led some scholars to suggest that the migration of anatomically modern Homo sapiens from beyond Africa and adjacent parts of Southwest Asia to South and Southeast Asia along the so-called Southern Route predated migration to Europe.
The date when humans first arrived in Australia via Sahul remains a contested issue, however, and some archaeologists and paleontologists are skeptical of the conclusions drawn from OSL dating at Madjedbebe and Nauwalabila I. Both sites are in areas where termites are active, and their tunneling can cause large rock fragments, such as stone tools, to be displaced downward into older layers, invalidating their associated dating with the sand surrounding them.
Nonetheless, the remains at Nauwalabila I offer vital clues about early Aboriginal culture and show the long and respected tradition of artists using ochre as paint in some of the oldest known artistic images. They also provide an important record of human interaction with the environment over tens of thousands of years.
