Due to its tucked away location, Chair 20 rarely operates as of 2017.View down from the summit.Top station and last tower with height adjustment option.Yan towers and chairs.Lift line with an offset tower.First section of the line.Tri-leg return terminal.Lift overview.Tension carriage and counterweight column.
That chair only gets used on crazy stormy days where nothing except for Chairs 7 20 and 21 could open, every now and then it got used for lift evac training. I remember last year chairs 13 20 21 and 25 were often closed on weekdays because of staffing issues, maybe something similar this year?

Yes. Chair 20 operates during storms when much of the mountain cannot be opened.

Does this ever run if the Upper Mountain is open? In a nutshell does Mammoth ever have all of their lifts open at one time?

I’d presume that it runs whenever they need to relieve traffic at Roller Coaster.

I just noticed that 20 was marked as “Closed for Season” on the trail map today. Anyone know why?
