Go up the orange (?) trail, which I think is also called the Brook trail, and then come down the blue trail. Up near the top, on your way down, there are a few spots, as I remember it, that are best done with small steps on your fanny
.
Or you can go back down the way you came up, or you can go down the back side of Mt Major, which is the "D" snowmobile trail. Follow the D trail to Jesus Valley road, turn left and follow it out to rte 11 and then back to the Mt.Major area.
