Narrative:
We were directed after dingo to proceed to calls for the visual to 11L. Shortly after; I told approach field was in sight; and we were cleared for the visual approach. I was sequencing the approach as the first officer preselected altitude of 5500 which should have been adequate for terrain clearance. He was descending at 800 fpm and I was about to suggest that he reduce the descent rate when we got the GPWS warning at approximately 5800 ft. His training kicked in and he immediately disconnected the autopilot and leveled the aircraft. The warning lasted only a couple of seconds and cleared.I have flown to tus many times and this has never happened. I believe the high descent rate was the underlying cause of this alert. In the future I will make sure the flying pilot is a little more conservative on the descent rate until passage of the terrain to the northwest of the airport.
