Vein Glory starts off pretty flat but gains steepness as it goes.
This goes right under the Union Creek lift and is a good trail for advancing the solid beginner to harder terrain.
This gets groomed often and is quite fun for most.
Sometimes, they close this trail and put boardercross/skiercross course here.
That is basically a race course with banks and jumps (and lots of nets to protect them) with racers going up to four at a time, much like motocross.
Be sure to check this out from the lift as it gives you the best vantage point.
