Using geophysical data, we identify crustal sills that presumably produce the high heat flow expression within the central and western Snake River Plain (SRP) region of southern Idaho. We invert receiver function waveforms and analyze seismic velocity datasets from IRIS to identify anomalous velocity layers in the mid-crust that may relate to either partial melt or cooled sills. Gravity and magnetic data is used to further constrain the locations of these sills. We find the majority of identified sills to be located along the southern portions of the western SRP, which is coincident with locations of high geothermal gradient.
