There are many wondrous, enigmatic and fascinating attractions on the Big Island of Hawaii, some better known than others, many out of the way and generally off the beaten track. Tour Guide Hawaii has produced an encyclopedic collection of the most up-to-date information, presented as short GPS-cued videos, in an app downloadable to iPhone and iPod Touch that covers the entire Big Island, highlighting the popular and the uncrowded, the famous and the secluded, the adventurous and the relaxing.

Here, at another large collapse crater formed by recent eruptions near the summit of Kilauea, a quick tour around Keanakako’i Crater will reveal fissures which were the source of lava flows in the 1974 eruptions. These eruptions were marked by enormous fire curtains and fire fountains. Also in this general area you will notice gravel sized pumice pebbles, formed from the froth of the lava which was ejected into the air, and cooled on its way down. Geologists call these pebbles “tephra”. There is a trail from Chain of Craters Road to the crater along which are some of the finest examples of “lava trees”.

NOTE: Currently Keanakako’i Crater is inaccessible, as a portion of Chain of Craters Road has been closed due to the current eruption in Halema’uma’u Crater.

600 feet wide and almost 500 feet deep, Puhimau Crater shows the typical morphology of a collapse structure that has not been invaded by post-collapse lavas. Notice how all the debris associated with this crater seems to point downward into the bottom of the crater; several talus cones run down the slope and there is no material stacked or scattered around the rim of the crater that is suggestive of eruptive or explosive events.

One can see exposed on the walls of the crater numerous pre-collapse lava flows that were truncated during the collapse. Obviously there is still molten rock close to the surface below this crater; one can generally see steam rising from numerous seeps. These steam seeps provide an oasis of moisture in the desert and lush steam gardens surround them.

Devil's Throat, Hawaii Volcanoes National Park: Photo by Donald B MacGowan

Less than 1/10 of a mile southwest along Chain of Craters Road from the Hilina Pali Road turnoff is a small patch of bare ground, the parking spot for the unmarked Devil’s Throat collapse crater. Devil’s Throat is an excitingly vertically-sided pit crater that is worth the visit just for the “okole squeezing” peering down the throat will give you.

An unmarked, approximately 50 meter trail leads south east from the road along a prominent earth fracture to the 30 meter wide by 55 meter deep pit. Keep your eyes on the trail in front of you at all times as you approach. Do not allow children or exuberant adults run ahead, especially in the dark, fog or vog, as there are NO safety rails and absolutely NO warning the crater is coming up…one simply arrives, teetering, at the brink. Be extremely careful approaching the crater rim, as the edge is very unstable and prone to collapse. It is also an interesting hike to trace the prominent fracture lines back towards Hilina Pali on the northwest side of the road to the prominent fault escarpment.

Collapse pit craters are formed when magma is rapidly extruded from one portion of a subterranean magma chamber to another, or is erupted onto land. The ground above the recently evacuated portion of the magma chamber simply collapses. Essentially, the entirety of the land traversed by chain of Craters Road is pocked with these features.

Viewing and photography are best done at Devil’s Throat when the sun is high in the sky and the walls and bottom of the crater are not in shadow.
