Zusammenfassung:	A steerable subsurface probe for particulate materials broadly includes a plurality of elongated, helically flighted adjacent bodies, a frame supporting the bodies, a drive assembly, and a cable. The drive assembly is operably coupled with the bodies for selective rotation of the bodies in respective rotational directions and at respective rotational speeds so that the probe may enter a mass of said particulate materials and move beneath the surface of said mass. The cable is attached to the frame, with the end of the cable remote from the frame being at a control location outside of the mass.
