I will report on novel integral-field observations of bright gravitational arcs, designed to map the spatial distribution of the intervening CGM at redshifts z~1.  Our observations have  enabled the first tomographic views of individual high-zgalaxy halos inabsorption, and  thus offer  simulations new and independent boundary conditions to constrainthe so-called 'baryon-cycle of galaxies.’
