This large specimen contains both forms of lava, pāhoehoe and ʻaʻā from Mauna Loa, Hawaii.  It is easy to see from the pictures that pāhoehoe lava is characterized by its smooth, ropey texture. It often forms into these twisted shapes as it cools. ʻAʻā lava is much more viscous than pāhoehoe and has a jagged, blocky surface. It contains large chunks of solidified lava. Because of its high viscosity, ʻaʻā lava tends to move much slower than pāhoehoe and often forms small mounds or piles when it stops flowing. It is easy to remember the difference in names, as when you step on ʻAʻā type of lava, it is very sharp and makes you want to say "ouch." Both forms of Mauna Loa's lava contribute to the dynamic landscape of the Big Island.

Mauna Loa is the world's largest active volcano and is located on the Big Island of Hawaii. The Mauna Loa volcano has erupted 33 times since 1843, with a full eruption occurring in 1984 and an astonishing 29 eruptions between 1843 and 1984. Mauna Loa is a shield-type volcano, which means it produces low viscosity, runny lava. The Mauna Loa volcano lava is known for two distinct types of lava: pāhoehoe and ʻaʻā.

Additional information: Moku‘āweoweo is the summit caldera of Mauna Loa. The name Mauna Loa means "long mountain, in Hawaiian and Moku`aweoweo means "abundance of Mauna Loa's molten rock," and refers to the expansive and diverse array of lava types produced by Mauna Loa.
