A late-1980 airborne EM/magnetic method test over the State Line kimberlite area of Colorado-Wyoming shows weak but recognizable anomalous responses to the known pipes. The magnetic survey indicates the presence of several shallow subsurface bodies adjacent to the known kimberlites, which are interpreted as possible blind diatremes. The survey data, in profile and contoured map form, has been correlated with geological map information available at the time. It can serve as the basis for reexamining kimberlite distribution in the area, taking into account geological findings during the recent work on known bodies.
