Because strong Lyman alpha emission is expected from young star forming galaxies at high redshift, it offers an efficient tool for identifying these galaxies. The Large Area Lyman Alpha survey is one of the first and largest successful searches for Lyman alpha emitting galaxies at high redshift. In the LALA Bootes field (which lies within the NOAO Deep Wide-Field Survey's Bootes field) we have obtained deep narrowband images covering 1/3 square degree in each of eight filters, sampling redshifts z=4.5, 5.7, and 6.5. We focus here on the higher redshift windows, where we have confirmed a luminous Lyman alpha emitting galaxy at z=6.535 and several others in the z=5.7 window. We discuss the physical properties of these objects, including their contribution to star formation rates and metal production. We also discuss the implications of Lyman alpha galaxy observations at z=6.5 for reionization.
