GeoGirls is a FREE program for youth in Washington and Oregon!

GeoGirls is a 5-day, 4-night geology and technology camp for girls (cis and transgender) at Mount St. Helens for girls in Oregon and Washington. During camp we will explore the volcanic eruption of Mount St. Helens, the hazards volcanic eruptions pose to the human population, and the technology used by scientists to monitor volcanoes. Our entire program takes place within the area affected by the 1980 eruption of Mount St. Helens. 

GeoGirls is a collaborative effort between the Mount St. Helens Institute and the U.S. Geological Survey – Cascades Volcano Observatory with partners from various scientific universities, agencies, and private companies. Throughout the week we will spend time with many different research teams hiking, exploring, collecting data, and team building. This is a unique experience, unlike any other summer camp! 

GeoGirls is only possible with the help of our fantastic science volunteers. Read about the GeoGirls 2023 research projects!
