Imagine looking up at a nearly vertical dam wall and seeing a herd of wild goats calmly climbing across it as if gravity barely existed. That is exactly what makes the famous Alpine ibex footage from Italy so extraordinary. In the BBC’s Forces of Nature with Brian Cox, Alpine ibex climb the steep face of the Cingino Dam in Piedmont, moving across surfaces that appear almost impossible for a large animal to negotiate. The reason is not simply athletic ability: the ibex are seeking mineral-rich salts deposited on the dam wall.
The animals featured in the footage are Alpine ibex, scientifically known as Capra ibex. They are specialized mountain ungulates whose bodies and hooves allow them to negotiate extremely steep rocky terrain. The Cingino Dam is located in Antrona Schieranco in Italy’s Piedmont region and rises roughly 46–51 meters depending on the measurement standard used.
What looks like an impossible stunt is actually a remarkable example of animal anatomy, balance, friction and survival working together.
The Incredible Scene on the Dam Wall
The BBC footage opens with an extraordinary sight: Alpine ibex positioned on the face of a huge dam.
Instead of staying on relatively safe ground, the animals begin moving up the wall.
Their hooves find tiny irregularities in the surface while their bodies remain remarkably close to the concrete and masonry. Some individuals appear to move almost horizontally before gradually working their way upward.
The visual effect is astonishing.
From a human perspective, the wall appears too steep to climb without ropes or specialist equipment. For the ibex, however, the steep surface is simply another challenge their anatomy can handle.
The BBC describes the scene as mountain goats climbing a vertical dam wall in Italy because they are seeking elements essential to life.
Where Is This Incredible Dam?
The famous climbing takes place at Cingino Dam, also known as Diga del Cingino, in the Antrona Valley of northern Italy.
The dam is part of a hydroelectric system in the Piedmont region.
The structure is surrounded by mountainous terrain, making it a fitting location for Alpine ibex. The reservoir is situated at an elevation of roughly 2,250 meters above sea level, although the surrounding landscape rises much higher.
The dam itself became internationally famous after photographs and videos showed ibex climbing its steep downstream face.
National Geographic documented the phenomenon after photographs of Alpine ibex on the dam became widely circulated, noting that the animals were climbing the near-vertical wall in northern Italy.
Why Are the Ibex Climbing a Dam?
The ibex are not climbing the dam simply to demonstrate their impressive abilities.
They are searching for mineral salts.
According to the BBC’s description, minerals from the rock used in the dam have been dissolved and deposited on its surface. These mineral-rich deposits provide substances that are important to the animals’ bodies.
The dam therefore accidentally creates something valuable for the ibex.
What humans built as infrastructure has become a source of minerals for wild animals.
This is one of the most fascinating aspects of the behavior.
The Ibex Are Looking for Salt and Minerals
Wild herbivores need more than grass and leaves.
Their bodies require minerals such as sodium, calcium and other elements for physiological processes, including maintaining bones, muscles and nerves.
The BBC explains that mineral deposits on the dam provide the ibex with essential nutrients, helping explain why they are willing to undertake such a dangerous-looking climb.
Mineral-seeking behavior, sometimes called geophagy or mineral licking depending on the behavior involved, occurs in many herbivorous mammals.
Animals may seek mineral-rich soil, rocks, water or other natural sources when particular nutrients are valuable or difficult to obtain from their normal diet.
Why Do They Need These Minerals?
Minerals have many roles inside an animal’s body.
Calcium is particularly important for bones and teeth, but it is also involved in muscle contraction, nerve signaling and other physiological processes.
Sodium and other electrolytes are important for maintaining fluid balance and normal nerve and muscle function.
For a mountain animal constantly running, jumping and climbing across difficult terrain, maintaining a functional musculoskeletal system is especially important.
The BBC specifically emphasizes the importance of calcium and other minerals for the ibex seen in the footage.
The Amazing Hooves of an Alpine Ibex
The secret behind the ibex’s climbing ability begins with its feet.
An Alpine ibex has specialized cloven hooves.
Each hoof is divided into two main toes, allowing the animal to position its feet with remarkable precision.
But there is another important feature.
The underside of the hoof contains softer tissue that can increase traction against hard surfaces.
Instead of behaving like a simple solid block, the hoof can interact with irregularities in rock and masonry.
This combination allows an ibex to place its feet on surprisingly small footholds.
How Can an Ibex Grip Such a Steep Surface?
The dam wall may look smooth from a distance, but it is not perfectly featureless.
Small cracks, edges, stones and irregularities can provide footholds.
An ibex carefully places its hooves so that its weight remains supported.
The animal also constantly adjusts its body position.
Every step changes its center of mass, meaning the ibex must maintain a delicate balance between gravity pulling it downward and friction and contact forces keeping it against the wall.
This is one reason the movement looks so controlled.
Ibex Hooves Work Like Natural Climbing Equipment
Humans who climb steep rock faces often rely on specialized footwear with high-friction rubber.
Ibex have their own biological version of specialized climbing equipment.
The outer hoof provides a hard structure for contacting surfaces, while softer areas underneath help provide traction.
Scientific research has measured the interaction between Alpine ibex hooves and dam-wall surfaces and found a relatively high coefficient of friction between the animals’ hooves and concrete.
That friction is one of the physical reasons the animals can remain stable on surfaces that appear almost vertical.
The Science Behind the Gravity-Defying Climb
The ibex are not actually defeating gravity.
Gravity is pulling them downward the entire time.
What they are doing is using their anatomy and the forces between their hooves and the wall to prevent themselves from sliding.
For an animal standing on a steep surface, several forces matter.
Gravity pulls downward.
The surface pushes back against the animal.
Friction resists sliding.
The ibex’s muscles position its legs and body so that its weight remains supported by the available contact points.
When those forces are balanced effectively, the animal can remain on the wall.
The Wall Is Steep, But the Ibex Adjust Their Route
Scientific observations of Alpine ibex climbing dam walls have provided some fascinating information.
Researchers filmed ibex on two Italian dam walls, including surfaces ranging from steep slopes to sections approaching vertical. They found that the animals often used zigzag routes while climbing.
This is important.
Instead of simply charging directly upward, an ibex can alter its path to manage the gradient.
A zigzag route can reduce the effective steepness of the path compared with moving directly up the wall.
Humans use a similar principle when building switchback trails on mountains.
Ibex Can Climb Steeper Than You Might Expect
A scientific study examining Alpine ibex locomotion found that some individuals traveled on extremely steep dam-wall sections.
The researchers recorded paths with gradients approaching or exceeding what would appear almost vertical from the ground. Young ibex and smaller animals were particularly capable of negotiating very steep sections.
The study found that climbing performance was influenced by body mass.
Smaller ibex and kids were able to negotiate steeper gradients than larger individuals in the observed dam-wall experiments.
That finding adds an important scientific dimension to the spectacular footage.
The climb is not just about courage.
Body size, friction, balance and locomotion all matter.
Why Do Young Ibex Look So Comfortable?
The BBC footage includes young ibex following adults across the steep surface.
A young ibex may look particularly vulnerable because of its small body and the enormous drop below it.
Yet the young animals have the same fundamental climbing adaptations as adults.
In the scientific observations of dam-climbing Alpine ibex, kids were among the animals capable of negotiating the steepest recorded paths.
Their smaller bodies may actually provide an advantage on extremely steep surfaces.
The Baby Ibex Follows Its Mother
One of the most memorable elements of the BBC sequence is the sight of a young ibex following an adult across the dam.
For viewers, this makes the climb even more dramatic.
The young animal must place its feet carefully while following the route taken by the adult.
However, it is important not to assign a human emotional explanation to the behavior. What can be observed is that young ibex can follow adults across difficult terrain, while the exact motivation of any individual animal cannot be established from the footage alone.
Why Smaller Ibex Can Have an Advantage
Body weight becomes increasingly important as slopes become steeper.
The heavier an animal is, the greater the force of gravity acting on it.
A smaller animal therefore has less weight pulling it away from the surface.
Research on Alpine ibex dam climbing found that climbing performance was negatively influenced by body mass, with smaller ibex capable of traveling on steeper gradients than larger individuals.
This helps explain why young ibex can sometimes appear remarkably capable on terrain that would challenge much larger adults.
Not Every Ibex Climbs the Dam
The spectacular footage should not create the impression that every Alpine ibex routinely climbs vertical dams.
Researchers studying dam-wall climbing observed different age and size classes and noted that large males were not observed climbing the studied dam walls.
That detail is particularly interesting.
The behavior appears to be influenced by body size and the physical demands of the wall.
The smallest and lighter animals can have an advantage when negotiating the steepest sections.
Why the Dam Is So Useful to the Ibex
Natural mountains already provide Alpine ibex with mineral sources.
But the dam has created an unusual artificial surface where mineral deposits can accumulate in accessible locations.
National Geographic reported that Alpine ibex climb the Italian dam in summer to access mineral deposits on the structure.
The animals are therefore exploiting a resource created unintentionally by human construction.
This is a striking example of wildlife adapting to a modified environment.
The Cingino Dam Became a Wildlife Internet Sensation
Photographs of ibex climbing the dam became famous long before the BBC video.
National Geographic reported in 2010 that images of Alpine ibex clinging to the Cingino Dam were circulating widely online. The images were sometimes incorrectly described as showing bighorn sheep climbing a dam in Wyoming, but the animals were actually Alpine ibex in Italy.
The distinction matters because Alpine ibex and North American bighorn sheep are different species.
The viral photographs helped introduce millions of people to one of the world’s most impressive examples of mountain-animal locomotion.
Alpine Ibex Are True Mountain Specialists
The Alpine ibex is native to the European Alps.
Its natural habitat includes steep mountainous terrain where sure-footed movement can make the difference between reaching food and falling.
Over generations, natural selection has favored physical traits that allow these animals to move efficiently through difficult landscapes.
Their climbing ability is therefore not an isolated trick.
It is part of a broader mountain-adapted lifestyle.
What Does an Alpine Ibex Eat?
Alpine ibex are herbivores.
Their diet consists primarily of vegetation such as grasses, herbs, leaves and other available plant material.
Their normal food provides energy, but mineral requirements can vary with factors such as age, reproduction and environmental conditions.
This is one reason mineral-rich locations can become attractive to herbivores.
The dam does not replace their normal food.
It provides an additional resource.
The Climb Is a Nutritional Investment
From the ibex’s perspective, climbing the wall has a cost.
The animal must expend energy.
It also faces a risk of falling.
Yet the behavior persists because the potential nutritional value of the mineral deposits can make the climb worthwhile.
This is a common principle in animal ecology.
Animals routinely balance energy expenditure, nutritional benefits and physical risks.
A mountain goat climbing a dam is simply expressing that principle in an extraordinary environment.
Why Don’t the Ibex Fall?
This is probably the first question most people ask after seeing the footage.
The answer is a combination of hoof structure, friction, balance, body positioning and careful movement.
The ibex is not relying on a single magical adaptation.
Every step is part of a mechanical system.
The animal’s weight pushes against the surface, the hooves create friction, the legs adjust body position and the animal selects footholds that can support its weight.
Scientific measurements of ibex locomotion on dam walls demonstrate that the animals can generate sufficient traction to negotiate very steep surfaces.
What Happens If an Ibex Missteps?
A fall from a steep dam wall could obviously be dangerous.
That risk makes the animals’ precision even more remarkable.
But wild animals do not calculate risk using human concepts such as “this is terrifying.”
Their behavior has evolved through natural selection, and animals that are poorly adapted to difficult terrain are less likely to survive and reproduce.
The ibex’s remarkable confidence is therefore better understood as the result of specialized locomotion rather than human-like fearlessness.
The Difference Between a Rock Face and a Dam
Alpine ibex naturally climb rocky mountain slopes.
A dam is different.
Its surface is artificial and can contain relatively regular sections of concrete or masonry.
Yet the animals are able to use small irregularities and surface texture to gain traction.
The scientific studies of ibex on dam walls are particularly useful because they show that the animals’ climbing ability is not limited to natural rock.
Their locomotion can work on human-made surfaces as well, provided the friction and footholds are sufficient.
The Incredible Precision of Each Step
Watch the ibex closely and the climb becomes even more impressive.
The animal does not simply run upward.
It makes a sequence of small, controlled movements.
One hoof moves.
The body shifts.
Another hoof searches for support.
The animal’s head and torso adjust as its center of gravity changes.
Then the process repeats.
At a distance, it looks effortless.
Up close, it is an extraordinary display of biomechanical control.
How Fast Can an Ibex Climb?
The scientific observations provide some useful measurements.
Researchers recorded Alpine ibex moving uphill at speeds of up to approximately 2.6 meters per second for kids on the steepest observed paths, while other size classes showed different maximum speeds. Downhill movement could also be surprisingly rapid.
The animals therefore do not necessarily move slowly simply because the terrain is steep.
Their movement can include walking and faster gaits depending on the conditions.
Going Down Can Be Just as Impressive
Climbing upward gets most of the attention.
But descending is also mechanically demanding.
A downhill animal must control its movement while gravity accelerates it toward the bottom.
Researchers found that Alpine ibex sometimes used more linear routes when moving downhill compared with the zigzag routes used during ascent.
This difference suggests that the animals adjust their locomotion according to the direction of travel.
The Ibex Has a Remarkable Safety System
The safest way to understand the animal’s climbing ability is to think of its body as an integrated system.
Its hooves provide contact.
Its legs provide force.
Its muscles maintain posture.
Its joints absorb movement.
Its nervous system constantly processes information about body position and terrain.
Its eyes help locate the next foothold.
Together, these systems allow the ibex to operate in terrain where a human would require specialized equipment.
What the BBC Video Actually Shows
The video is from the BBC’s Forces of Nature with Brian Cox, a series that connects spectacular natural scenes with the physical forces governing our planet.
The exact YouTube video was published by BBC on July 12, 2016, and is identified as part of Series 1, Episode 3.
The sequence is particularly effective because it combines an extraordinary animal with a simple scientific question:
How can an animal stand on a wall that appears impossible to climb?
The answer lies in physics and biology working together.
The Ibex Is Not Defying Gravity
The title says the ibex “defies gravity,” but scientifically the animal is not breaking the laws of physics.
Gravity is still acting on it.
The ibex succeeds because its feet and body generate forces that counter the tendency to slide downward.
In other words, the animal is not defeating gravity.
It is using friction and biomechanics to live with it.
That distinction makes the behavior even more impressive.
A Perfect Example of Evolution and Physics
The Cingino Dam ibex provide a spectacular example of how biological evolution can produce animals capable of exploiting difficult physical environments.
The dam did not evolve alongside the ibex.
But the animals already possessed climbing abilities developed for mountainous landscapes.
When a human-made structure presented a sufficiently textured surface and a valuable mineral resource, those abilities became useful there too.
This is a fascinating intersection of ecology, evolution and physics.
Why the Ibex Does Not Need Climbing Equipment
A human climber needs ropes, harnesses, specialized footwear and careful route planning.
The ibex carries its climbing equipment with it.
Its hooves are permanently attached.
Its legs are designed for mountain movement.
Its balance system operates automatically.
Its muscles respond rapidly to changes in terrain.
Its body has been shaped by evolution rather than manufactured in a workshop.
The result is one of nature’s most impressive natural climbing systems.
A Mountain Animal Taking Advantage of a Human Structure
There is something especially interesting about the relationship between the ibex and Cingino Dam.
Humans built the dam for water and hydroelectric infrastructure.
The ibex have found a completely different use for it.
The structure has become a source of minerals.
This does not mean the dam was intentionally designed as wildlife habitat.
Instead, the animals discovered that the artificial environment provided something useful.
Why This Behavior Became So Famous
Many wildlife behaviors are spectacular, but few are as visually easy to understand as an animal walking vertically up a wall.
You do not need specialized knowledge to appreciate how difficult it looks.
That visual quality helped the Cingino ibex become an internet phenomenon.
National Geographic’s coverage in 2010 helped popularize the images, and the BBC’s later footage introduced the behavior to an even wider audience.
The Cingino Dam and the Alpine Landscape
The Cingino Dam sits within a mountainous region of Piedmont.
The surrounding environment is very different from the flat landscapes where many people are accustomed to seeing domestic goats.
Here, steep slopes and rocky terrain dominate.
For an Alpine ibex, such landscapes are normal.
The dam simply provides an unusually extreme version of the same climbing challenge.
A Reminder of How Specialized Wild Animals Can Be
The ibex footage is a reminder that wildlife often possesses abilities that are easy to underestimate.
An animal that looks like an ordinary goat at ground level can become an extraordinary climber when placed on steep terrain.
Its physical abilities only become obvious when we see them pushed to their limits.
This is why videos such as this one are so valuable for wildlife education.
They reveal adaptations that might otherwise remain invisible.
The Young Ibex Makes the Climb Even More Amazing
Perhaps the most memorable part of the BBC sequence is seeing younger ibex negotiate the wall.
Their smaller bodies make them appear delicate compared with the huge structure beneath them.
Yet they move with the same fundamental confidence as the adults.
Scientific observations support what the footage suggests: young Alpine ibex can be exceptionally capable on steep dam walls, with kids recording some of the steepest paths in the study.
Nature’s Ultimate Cliff Climbers
Alpine ibex are among the most impressive naturally occurring mountain climbers.
They can move across rocky slopes where a single mistake could have serious consequences.
The Cingino Dam simply gives us an unusually clear view of those adaptations.
Instead of seeing the animal against a natural mountain background, we see it against a giant human-made wall.
The contrast makes the ability impossible to ignore.
