We report the results of first experimental and theoretical studies of two-dimensional (2D) Wigner solid (WS) motion on the free surface of normal and superfluid 3He, at ultra-low temperatures down to 0.24 mK. It is shown that the WS transport is determined thoroughly by the bulk Fermi-quasiparticle scattering at the surface dimple sublattice produced by localized electrons. Besides interesting electronic properties of the system, the 2D WS serves as a powerful probe for the bulk properties of superfluid 3He.
