creating projects for undergraduate research, master's thesis, and doctoral dissertations. A list of currently funded proposals can be found on the NSF website. Legacy Many applications for EarthScope data currently exist, as mentioned above, and many more will arise as more data becomes available. The EarthScope program is dedicated to determining the three dimensional structure of the North American continent. Future uses of the data that it produces might include hydrocarbon exploration, aquifer boundary establishment, remote sensing technique development, and earthquake risk assessment. Due to the open and free-to-the-public data portals that EarthScope and its partners maintain, the applications are limited only by the creativity of those who wish to sort through the gigabytes of data. Also, because of its scale, the program will undoubtedly be the topic of casual conversation for many people outside of the geologic community. EarthScope chatter will be made by people in political, educational, social, and scientific arenas. Geologic Legacy The multidisciplinary character of EarthScope will create stronger network connections between geologists of all types and from around the country. Building an Earth model of this scale requires a complex community effort, and this model is likely to be the first EarthScope legacy. Researchers analyzing the data will leave us with a greater scientific understanding of geologic resources in the Great Basin and of the evolution of the plate boundary on the North American west coast. Another geologic legacy desired by the initiative, is to invigorate the Earth sciences community. Invigoration is self-perpetuating as evidenced by participation from thousands of organizations from around the world and from all levels of students and researchers. This leads to a significantly heightened awareness within the general public, including the next cohort of prospective Earth scientists. With further evolution of the EarthScope project, there may even be opportunities to create new observatories with greater capabilities, including extending the USArray over the Gulf of Mexico and the Gulf of California. There is much promise for EarthScope tools and observatories, even after retirement, to be used by universities and professional geologists. These tools include the physical equipment, software invented to analyze the data, and other data and educational products initiated or inspired by EarthScope. Political Legacy The science produced by EarthScope and the researchers using its data products will guide lawmakers in environmental policy, hazard identification, and ultimately, federal funding of more large-scale projects like this one. Besides the three physical
