After passing through the through truss bridge you rounded a curve and passed through the town of Divide, all still on a very steep grade.
You then headed down grade around two more curves before arriving at Greasewood Canyon (pictured here in the foreground) where you were once again going up grade and around one more curve before arriving at Puma, the second main yard (pictured here in the center background).
The mainline from the through truss bridge headed to Divide is over by Dan Mulhern (yellow shirt).
Las Vegas is on the upper level in the far back.
