  We show that in type-II superconductors a magnetic field applied transversely
to correlated columnar disorder, drives a phase transition to a distinct
"smectic" vortex glass (SmVG) state. SmVG is characterized by an infinitely
anisotropic electrical transport, resistive (dissipationless) for current
perpendicular to (along) columnar defects. Its positional order is also quite
unusual, long-ranged with true Bragg peaks along columnar defects and
logarithmically rough vortex lattice distortions with quasi-Bragg peaks
transverse to columnar defects. For low temperatures and sufficiently weak
columnar-only disorder, SmVG is a true topologically-ordered "Bragg glass",
characterized by a vanishing dislocation density. At sufficiently long scales
the residual ever-present point disorder converts this state to a more
standard, but highly anisotropic vortex glass.
