Photo Gallery

The broad Haleakalā shield volcano towers over the eastern part of the island of Maui, seen here from the beach at Kihei on the west flank. Its summit profile is irregular because of the many scoria cones that have erupted along the SW rift zone, which extends from the coast to the summit. The lava flow in the foreground also originated from Haleakalā.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
Halali'i (center foreground) and Pu’u o Maui (left center) are two of a series of young scoria cones erupted within the Haleakalā crater. Unvegetated lava flows form much of the crater floor, seen here looking NW from Pu’u Naue scoria cone. The crater is one of the few locations where the rare native-Hawaiian silversword ('ahinahina) plant is found.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
Kamoa o Pele (left) and Pu’u o Maui (right) are two of a group of young scoria cones along the southwest rift zone within the Haleakalā crater, seen here looking westward towards the Haleakalā summit.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
Pu’u o Maui is the largest of a group of scoria cones erupted along a rift zone that passes across Haleakalā crater, with the western crater rim to the upper left. The large summit crater formed through erosion and collapse events.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
Recent activity at Haleakalā took place from vents low on the SW rift zone. The lava flows that form the coastline below originated from two vents, one near where this photo was taken and the other below the scoria cone near the center. Kaho’olawe is in the distance to the SW.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
Pu’u Olai is a scoria cone on the west flank of Haleakalā that formed during the late-stage Hana Series eruptions, which produced a large number of scoria cones and lava flows along the SW and E rift zones.

Photo by Lee Siebert, 1987 (Smithsonian Institution).
The summit of Haleakalā on the island of Maui contains a large crater that opens towards the ENE. It formed by the erosion of two large valleys that eventually coalesced, along with collapse events. This view to the NE from near the summit shows the Ko’olau Gap in the distance and scoria cones on the crater floor from eruptions along a major rift zone that extends across the summit from the SW to eastern coasts.
