June 13, 2012 - Hawaiʻi Volcanoes National Park has reopened the section of Crater Rim Drive near the Devastation Trail parking lot to Keanakākoʻi Crater, and a portion of Crater Rim Trail that leads from Chain of Craters Road to the south side of Keanakākoʻi, to hikers from 7:00 a.m. to 7:00 p.m. daily.
Approximately 0.8 miles of Crater Rim Drive is now open to hikers, and visitors can enjoy an easy and accessible roundtrip walk through koa and ʻōhiʻa forest on pavement all the way to the Keanakākoʻi Crater overlook. Across the road, another overlook provides panoramic views of Halemaʻumaʻu Crater and Mauna Loa.
Keanakākoʻi, meaning "cave of the adzes", likely formed during the 1400s, during Kīlauea's great summit collapses. Until 1877, Hawaiian kahuna kākoʻi (carving experts) sought the crater's superior and rare basaltic rock for making koʻi, or adze heads. Bound to a sturdy ʻau koʻi (wooden handle), this valuable tool was used to carve vital objects like canoes and houses. But the famous adze quarry was covered by lava, first in 1877, then again during the fissure eruption in July 1974. Today, the crater floor is 115 feet deep.
The park closed Crater Rim Drive from Jaggar Museum to Chain of Craters Road and portions of Crater Rim Trail for public safety after Halemaʻumaʻu began to erupt in March 2008 and volcanic fumes caused poor air quality. Halemaʻumaʻu continues to erupt, and Crater Rim Drive remains closed from Keanakākoʻi to Jaggar Museum.

The two types of Hawaiian lava differ in appearance but are chemically alike. Pahoehoe has a smoother and ropey surface where a`a is jagged and clinkery.
