During the 9 hours of vigorous eruptive activity on May 18, 1980, about 540 million tons of ash from Mount St. Helens fell over an area of more than 22,000 square miles (57,000 square kilometers). The total volume of the ash before its compaction by rainfall was about 0.3 cubic mile (1.3 cubic kilometers), equivalent to an area the size of a ... No volcanoes existed in Kansas during Tertiary and Quaternary times so a source outside the state must have been responsible for the large quantities of ash deposited here. Most of the Kansas ash was probably carried in by wind from a volcano in north-central New Mexico, eruptions in Yellowstone, Wyoming, and from Long Valley caldera in California. Paleogene to Neogene rocks in Kansas consist of river silt, sand, freshwater limestones, and some volcanic ash derived from eruptions in the western United States. Near the beginning of the Paleogene, the Rocky Mountains were formed, as were the streams and rivers heading eastward out from the mountains into Kansas.
