Two topographers working with an alidade and plane table. The man on the right is believed to be Roland Whitman Burchard, who was the topographer for the USGS Grand Canyon Expedition of 1923. Author Lewis Freeman described Burchard as a man of "powerful physique, great endurance, and a cool, steady hand."

Ejected tephra from Halemaumau at Kīlauea, May 31, 1925
This scene west of Halemaumau looks toward the rim of the caldera, southwest of Uēkahuna Bluff. New ballistic blocks and ash from the 1924 eruption coat the floor of the caldera.

Prior to the eruption of 1924, this area was swept clean and used as a landing field for airplanes. This view looking toward the north rim of Halemaumau shows the air field littered with ballistic blocks from explosions in the 1924 eruption.

Explosion from Halemaumau at Kīlauea May 18, 1924.
This was probably the strongest explosion of the eruption. Rocks and debris fell among spectators southeast of Halemaumau, causing one fatality. A torrential downpour and an electrical storm followed.

Eight persons, including newspaper and movie men observing the scene at Halema‘uma‘u, were caught in a rain of hot rocks from this explosion. The rocks emitted hissing sounds as hot gas, mainly steam, escaped from them. Park superintendent Thomas Boles was knocked down twice by this bombardment.

Boulder ejected from Halemaumau, at Kīlauea, May 11, 1925
On May 11, Ruy Finch and W.O. Clark visited Halemaumau and found a rock fragment weighing about 180 kg (400 pounds) that had been thrown 60 meters (200 feet) from the rim of the crater.

First explosion clouds from Halemaumau, Kīlauea 1925
Later scientists at the Observatory listed May 10 as the first day of the eruptive series. Between this date and May 27, they carefully recorded all explosions, ballistic falls, electric storms, and muddy rains as well as earthquakes felt and recorded on seismographs.

Valley of Ten Thousand Smokes, Katmai, Alaska, circa 1922
Valley of Ten Thousand Smokes in Katmai National Park, circa 1922. Windy Creek is in the foreground. Following the June 6, 1912 eruption of Novarupta-Katmai, thousands of fumaroles filled the valley for many years. Buried snow fields, glacial streams, and precipitation were converted to steam by the heat trapped in the pyroclastic flow.
