H I column density in a volume ﹩8\ h^{-1}\ \mathrm{Mpc}\,﹩ on a side and ﹩8\ h^{-1}\ \mathrm{Mpc}\,﹩ thick (comoving), from run C1 at ﹩z=3﹩. The insets are ﹩600\ h^{-1}\ \mathrm{kpc}\,﹩ (top) and ﹩80\ h^{-1}\ \mathrm{kpc}\,﹩ (bottom) on a side in comoving units, translating into an approximately 10 kpc (physical units) DLA around the disk galaxy in the center of the bottom panel. The DLA column densities correspond to green and up in the color map on the right. The resolved dynamic range in this model is 8192.
