Kīlauea's "Old Faithful"—a thing of the past

Detailed Description

"The whole Eastern Half of the lake is in a state of continuous activity with Old Faithful playing 10 to 20 feet every 35 to 45 seconds." J.M. Lydgate wrote these words and sketched this map of Halema‘uma‘u Crater in the Volcano House Register (a collection of hotel guest comments) in July 1909 to document his observations of Kīlauea Volcano. The red line on his sketch indicates the boundary of the lava lake at the time, and the location of Old Faithful is noted within the lake. Courtesy of National Park Service.
