Light transport aircraft flight crew reported flying an unstable approach resulting in flight towards terrain event. The flight crew landed safely at the airport.

Narrative

Approach to landing not compliant with stabilized approach criteriaVisual approach; mitigating high terrain. Approach flown as briefed and planned with the anticipation of the possibility of sink rate warnings and late approach stabilization on final approach. The possibility of go around was also discussed and at anytime either of the pilots would be uncomfortable or unsure of the safety and/or successful completion of the approach we agreed to call for the go around. We aimed for 1000 ft AGL at 3 mile final. The uncertainty about the height and slope of the terrain in the final approach area made me turn on a shorter final thus causing late approach stabilization being high on speed. At 500 ft AGL speed was Vref+20; idle power. I verified with the pilot monitoring if he was ok with our position and speed at this point of the approach. We both agreed to continue for landing. The dilemma was flying lower above sloping terrain or being high on the approach but certain about the terrain clearance. We choose the higher profile over approach stabilization criteria. On hindsight I (as pf) could have flown a slightly longer and lower final approach path. This was discussed in the de-briefing between the pilots. Landing was in touch down zone and runway exit as calculated and planned.High and steep sloping terrain around the airport with limited to unknown information on the elevations. Need more information on the exact terrain heights around TRK airport. This will help altitude; distance; visual glide path judgement for circling and visual approaches into Truckee airport. Best would be to have visual approach charts with detailed terrain information in the airport vicinity.It is not safe to solely rely on visual judgement of terrain height during the visual part of the (circling) approaches into any mountainous terrain airport.
