The short answer: Denali is estimated to weigh on the order of roughly 800 billion kilograms (about 1.8 trillion lb), calculated from its large volume and the density of its rock. The figure is a rough estimate.
Denali weight by type
Denali, in Alaska, is the highest peak in North America at 6,190 m (20,310 ft). Its estimated weight comes from its volume and the density of its granitic and sedimentary rock.
| Aspect | Approximate figure |
|---|---|
| Summit height | 6,190 m (20,310 ft) |
| Primary rock type | mostly granite and sedimentary |
| Estimated mass | around 800 billion kg |
| In metric tons | around 800 million metric tons-plus order |
| Confidence level | rough order-of-magnitude estimate |
What affects Denali weight
- Volume. Denali's enormous height and broad base set the amount of rock involved.
- Rock density. Its granite and sedimentary rock determine mass per cubic meter.
- Base definition. Where the mountain's base is drawn changes the volume counted.
- Shape. The peak's broad, bulky form holds a vast amount of material.
- Snow and ice. Glaciers and ice cover add some weight on top of the rock.
- Estimation method. The figure is approximate, based on geometry and density.
How Denali weight compares
Denali's mass is far beyond everyday comparison; it dwarfs every human-made structure on Earth, with even the largest buildings being an insignificant fraction of its weight.
Frequently asked questions
How much does Denali weigh?
Denali is estimated to weigh on the order of 800 billion kilograms. This is a rough figure derived from its volume and rock density.
How is Denali's weight calculated?
Scientists estimate the mountain's volume from its dimensions and multiply by the average density of its granite and sedimentary rock. The result is approximate.
Does ice add much to Denali's weight?
Glaciers and snow add some weight, but the vast bulk of Denali's mass comes from its rock. The ice cover is small by comparison.
