The Jaggar Museum (wing of building in lower left) was part of HVO before 1986. It was remodeled by the National Park Service at the same time that HVO's large new building was constructed (building with tower). From the Museum's circular overlook, visitors can look across Kilauea's caldera to Pu`u Pua`i (Kilauea Iki's cinder cone), the Steaming Bluff, the Volcano House Hotel (the original site of HVO), and toward the upper east rift to the Mauna Ulu shield, which was built by eruptions between 1969 and 1974. Inside the museum, located immediately behind the overlook platform, exhibits show volcano-monitoring methods used by HVO scientists. The museum is open to the public 8:30 a.m. to 5:00 p.m. daily. HVO itself is a research facility not open to the public except by special appointment.
