Using an early sample of over 400 high redshift QSO spectra from the Sloan Digital Sky Survey (SDSS), we present one-dimensional line-of-sight power spectra of Lyman-alpha absorption spanning scales from 100 to 10,000 km/s. We then reconstruct the three-dimensional real-space mass power spectrum, the most precise power spectrum to date at redshifts 2 < z < 4.
