Abstract
Stellar winds of massive stars seem rarely to leave easily identifiable and explained dynamical imprints on the surrounding interstellar medium. The sensible, classically-predicted wind bubbles are few and far between. As part of a concerted effort to solve the puzzle that this presents, we carefully investigate the gas and dust environment of the Wolf-Rayet star WR155. An arc of material seen in ^{12}CO data, faintly in infrared images, and more faintly yet in the HI images is the most likely signpost of the star's interaction with its environment.
