Human Factors
On a visual approach to Runway 16L while descending to 7000 ft. we received a GPWS warning. I leveled off around 7;100 ft. and had the terrain in sight the entire time. After passing the hill I started a descent and was unstable so we went around.We were expecting the RNAV Y 16L but were taken off because of departing traffic on Runway 34R. This lead to an extended downwind and base to final. We were much farther out than we briefed or expected. When we finally turn final I used the RNAV 16 X approach plate for distance and altitudes. Over 'BADPE' fix the altitude is 6900 ft. I set 7;000 and started to descend my rate was too much and we received the GPWS warning. [Pilot flying suggests] when operating in mountainous terrain on an RNAV approach and you are taken off that approach see if there is another approach that is better suited for your new location and situation; and familiarize yourself with it before even starting a visual approach.
A-319 Captain reported a CFIT event during approach that was extended due to departure traffic.
