The Lava Trees of Hawaii
When hot lava from a volcanic eruption invades a forest, often the lava does not overthrow the larger trees, but flows around them. The moisture in the tree cools the lava in contact with the trunk and a hard exterior shell is formed. As the lava drains away, only the solidified “lava trees” are left standing.
The tremendous heat burns away the wood inside and a hollow cast in the shape of the original tree is left behind. In some cases, the tree can remain standing and stays for years as a black charred skeleton, and in rare cases, some trees even survive and continue to grow after the eruption. (Source)
