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.

1923 Survey of the Grand Canyon of the Colorado River in Arizona
The survey of the Grand Canyon of the Colorado River in Arizona. This survey, perhaps the most difficult ever undertaken by government engineers, was made to show the possibilities for development of power. Every feasible dam site was surveyed and the flow of all tributary streams was measured.

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.
