Delineate the subsurface geology
The Raft River Valley occupies an upper Cenozoic structural basin filled with nearly 1600 m of fluvial silt, sand, and gravel. Rapid facies and thickness changes, steep initial dips (30 0C), and alteration make correlation of basin-fill depositional units very difficult. The Raft River geothermal system is a hot water convective system relying on deep circulation of meteoric water in a region of high geothermal gradients and open fractures near the base of the Tertiary basin fill.
