The stadium consisted of an uncovered one-level grandstand, stretching from foul pole to foul pole, with small bleacher stands in right and left field. One baseball annual published just before the 1962 season referred to it as "a barn-like thing." It is best remembered for the horribly hot and humid weather (and attendant mosquito population) that had necessitated building the first domed stadium. The field was conventionally aligned northeast (home to center field) at an elevation of 50 feet (15 m) above sea level.

Temporary from the outset, the stadium was abandoned when the Astrodome was completed for the 1965 season. The Astros occasionally used it for running and exercising to acclimatize players to warm weather before a road trip. However, the players had to be careful, as rattlesnakes would often take up residence on the field. Monsanto engineers also used it as a testing ground for its synthetic ChemGrass, later known as AstroTurf, inviting cars and horses to ride on the synthetic surface to gauge its durability. It sat abandoned for ten years, accumulating random odds and ends from nearby Astroworld and weathering in the blistering Texas sun.

The right field corner of the stadium was located in what is now the northwest corner of NRG Center. Much of the northern half of the stadium (center field, left field and the third base stands) is occupied by a power station, and home plate was approximately located where a light pole in the adjacent parking lot is.
