Southern Front of Lava Flow from Pu`u `Ō`ō

This Quicktime movie shows the southern front of the June 27th lava flow from Pu‘u ‘Ō‘ō. Lava here has flowed into a deep crack on Kīlauea's East Rift Zone. The line of steam extending out from the visible flow margin at the surface is inferred to be caused by lava deep within the crack. This video also shows the lava stream beneath the flow surface, supplied by a lava

Lake Waiau, at an altitude of 3,969 m (13,020 ft) atop Mauna Kea, is the only alpine lake in the Hawaiian island chain. It is thought to have formed at the end of the last glacial retreat, which in Hawai`i was almost complete by 15,000 years ago.
