Tell Glade is a misleading name.
This is a wide open mogul field, without the trees that most people would associate with a glade.
Tell Glade gets its black diamond rating more from the bumps than from the pitch, though it is steeper than blue runs.
There is a great amount of room to practice here, which many ski classes do.
It has been groomed before, but you could stay an entire season and never see it flat.
