Visual observation of flow in a fully developed turbulent boundary layer along a two-dimensional channel has revealed the presence of systematic vortices both in the longitudinal and the transverse directions. In some cases a pair of longitudinal vortices has been observed connected together by a transverse one in a horseshoe configuration. As the vortices are convected downstream they grow and decay, finally dispersing as new structures are formed. An attempt has been made to characterize these vortex structures in terms of the wall layer parameters.
