The 11-minute VR video, narrated by Obama, is one part paean to the wonders of America’s national parks and one part warning of the threat posed by climate change. (AP Photo/Jacquelyn Martin, File)

The current lava flow erupted from a vent on the volcano in May and made its way to the sea in late July. Visitors can hike about 10 miles round trip to see the lava flow, or take a boat or helicopter tour to see the flow. (AP Photo/Caleb Jones)
