Lava Trees and Tree Molds
There are two types of Hawaiian lava, a'a which is rough, chunky,
and crumbly and Pahoehoe, which is smooth, flowing and ropy. While
chemically alike the two types of lava appear differently because
the Pahoehoe lava is hotter and contains more gas than A'A lava
and thus Pahoehoe creates flows that appear very fluid.
During periods of fountaining eruptions lava thrust into the air
cools quickly forming smooth black droplets which are known as Pele's
tears or glasslike strands that are known as Pele's hair. When touring
the park these various forms of lava can be observed in many locations.
Desolation trail is especially good for spotting Pele's tears and
