While snow and ice dominate Snow Rider 3D, rocky terrain is common. These rocks and boulders may mix in with the snow or be buried in unexpected places, making them difficult to avoid. A huge boulder might cause a rider to tumble, lose momentum, or be hurt. These obstacles need accuracy to handle when placed in the center of the track or on a steep hill. A boulder near a jump may require the rider to make a deliberate maneuver to clear it or take a detour.
