We present results from a survey of the Lyman alpha forest at 2.15<z<3.26 toward ten QSOs concentrated within a 1 degree field. We find correlations of the Lyman alpha absorption line wavelengths between different lines-of-sight over the whole redshift range. This indicates the existence of large-scale structures in the Lyman alpha forest extending at least over ~36/h comoving Mpc in the plane of the sky, as may be expected from recent large scale structure simulations.
