The Quarry is where Keith Foster, the architect, got his recognition, and deservedly so. It's located just south of the San Antonio Airport, and is built, at least the back nine, in a former rock quarry. It can play to 6,740 yards and 128 slope from the tips, but has 2 other sets of tees. The front nine is more links style with slightly rolling fairways, bordered by tall native grasses. The back nine is a drastic change from the front as you play through the pit with elevated tees, and forced carries over chasms from the former quarry, and is entertaining and fun to play. The routing is framed by a lake, limestone cliffs at least 125 high, and some fantastic views over the course. The grasses are tall, and the rough is thick, so be prepared for a challenge. It is open to the public with a country club atmosphere, the grounds are immaculate.
