    I love the snowshed part, it’s pretty incredible when you go in it. I was wondering if they could upgrade it to a DTQ and still keep the snowshed since this should be a DTQ sometime around now.

      Not likely. Yan Triples typically had a 13 foot line gauge and bullwheel- too narrow for a detach quad at a typical 15 foot. And you’d really need to remove the shed to build the new terminal.

      There’s no need for an upgrade to 23. As it is, it has a 5-6 minute ride time, and is intended to serve only expert terrain. Given that Mammoth is the most-skied areas in North America, all a detachable will do is encourage people to ride it that have no business being at the top of 40º+ runs.

    I’m surprised this hasn’t been converted to hydraulic tensioning like a lot of other Yans out there. I feel like if they would take the time to remove chairs from the line and the haul rope to upgrade the tensioning system too.
