Pine Twig Torches Lit the Way for 14,400-Year-Old Cave Explorers 2026

Pine twig torches, not thick wooden logs, were the lighting tool of choice for a small group of Paleolithic explorers who crossed a pitch-black cave in what is now Italy roughly 14,400 years ago. The finding comes from the Bàsura cave near Toirano in Liguria, where researchers have spent a decade piecing together how five people and a dog navigated nearly 800 meters of underground passage in total darkness.

The study, part of the multidisciplinary "Bàsura Revisited" project, analyzed 56 fragments of charcoal recovered from the cave floor. More than half of the pieces came from young branches of Scots pine (Pinus sylvestris) or closely related species, measuring just two to three centimeters in diameter. In other words, the group did not haul heavy torches into the cave. They carried bundles of thin pine twigs picked from living trees.

Why Pine Twig Torches Made Sense Underground

Our instinct today is that a bigger piece of wood burns longer and therefore gives more light. That intuition is exactly what the Bàsura evidence challenges. A thick trunk is heavy, awkward to carry through narrow passages, and slow to ignite. Thin pine twigs, by contrast, are light, resin-rich, and easy to bundle into a compact torch that catches fire quickly.

The researchers suggest the twigs were gathered from living trees rather than scavenged from the ground, which implies planning before the group ever entered the cave. That level of forethought matters: it shows these hunter-gatherers understood their lighting needs and prepared for them in advance.

What the Charcoal Fragments Reveal

The charcoal analysis is the core of the discovery. By identifying the wood species and the size of the branches, the team could reconstruct not just what burned but how it was selected. The dominance of small-diameter pine is a strong signal that the lighting strategy was deliberate and consistent.

• 56 charcoal fragments were recovered and analyzed from the cave floor.
• More than half came from young pine branches under three centimeters thick.
• The wood was likely collected from living trees, not deadfall.
• The group included five people and a dog, based on earlier trace evidence.
• The journey covered almost 800 meters of dark underground gallery.
• The event dates to about 14,400 years ago, during the last glacial period.

Who These Cave Explorers Were

The Bàsura group belonged to a culture of hunter-gatherers living during the last ice age. They were not casual visitors. Entering a deep cave in complete darkness required coordination, a reliable light source, and a reason to go. The presence of a dog alongside five humans adds a striking domestic detail to an otherwise sparse archaeological record.

Earlier research at the site documented footprints, handprints, and traces of crawling through tight passages. The new charcoal work fills in a missing piece: how they saw where they were going. Together, the evidence paints a picture of a small team moving carefully through the cave with handheld pine twig torches.

How Pine Twig Torches Compare to Other Lighting

Not all prehistoric lighting was equal. The Bàsura find sits within a broader picture of how early humans made fire work for them in enclosed spaces. The table below compares the practical trade-offs of common lighting materials.

Why the Discovery Matters for Archaeology

Fire use is one of the defining behaviors of early humans, but evidence of how fire was actually deployed in daily life is rare. The Bàsura charcoal gives researchers a concrete case of lighting strategy tied to a specific journey. It also raises new questions about how much planning went into cave exploration during the Paleolithic. The background to this story is set out in Trending: latest articles.

The finding nudges us away from the cinematic image of a blazing torch and toward something more practical: small, resinous bundles that could be lit, carried, and replaced as the group moved deeper. That shift in perspective is valuable because it grounds prehistoric behavior in real constraints of weight, fuel, and time. Earlier coverage in Farmer Uncovers 3,200-Year-Old Statue of Ramses II in Egypt shows how the argument developed.

What to Watch Next

Future work at Bàsura will likely focus on how the twigs were bundled and how often they were replaced along the route. Residue analysis and experimental burning could test how long a pine twig torch actually lasts underground. Each answer will sharpen the picture of a five-person team and their dog making their way through the dark.
