Popis:	We study the nature of damped Lya absorption (DLA) systems at z= -17) to the total neutral gas cross section is not necessary; (4) of the 11 DLAs studied, 45% are disk dominated, 22% are bulge dominated, 11% are irregular, and 22% are in galaxy groups, indicating that galaxies that give rise to the DLAs span a wide range of morphological types and arise in a variety of galaxy environment; (Abridged) Comment: 52 pages, including 17 figures; ApJ in press; a complete version with full resolution figures are available at http://falcon.mit.edu/~hchen/pub.html
