School Marm is named this way because of its popularity as a location for ski and snowboard school lessons.
These lessons make this run fairly crowded, and at the end of the day in the late afternoon during ski out times this run becomes significantly more busy.
School Marm is located to the left of the Wizard Express, breaking off from Merlin's on the left side.
Conditions at this low of elevation can be variable in comparison with other areas you have skied on the mountain throughout the day, and are affected by the large amounts of traffic on this run.
School Marm quickly joins with Green Line and the Yellow Brick Road leading to Whistler Village, the day lots, Base II or the base of the Wizard Express.
