I-Map Series/Geologic Investigations Series
Possibly important to note – “In August 1996, the I-map series name was changed from Miscellaneous Investigations Series Maps to Geologic Investigations Series. All geologic maps approved for publication after August 1996 were published in the Geologic Investigations Series.”  searching using both terms couldn’t hurt after narrowing your research target area.
