I checked this swamp some 5 years ago and concluded the golf course to be safer assuming it is clear.
However it is worth checking it again, as well as the other fairways, the more options the better, but I conquer with everything else said. unless we find a real safe landing spot, better not taking this risk again. “sergio’s Elevator” works only 99% of the time... (probably less than 99%).

Just doing the math: Brockway summit at pavement level is 7200, that is a road cut and there are trees and power lines. The shoulder of Martis Peak is 8000, so a reasonable altitude with a small margin is 8500 crossing that ridge. If you got sink you could move further west were it is lower and maybe still get through. It is 10.3 miles from the north end of Marlette lake, call it 55,000 ft, or 1360 ft dropped in a 40:1. So 9860 is a low margin glide at MC0. This is why I use 10,500 in my 50:1 glider.
