Tuning Fork still has a ways to go. Not super wintery but definitely not isothermal. That said we bailed before 13k because the snow really sucked and wasn't getting better. Maybe it's better up higher but it was only getting icier as we ascended (at 2pm, lol)
Today despite the heat and sun it was pretty locked up even in the afternoon. Top of the snowpack was a very crusty 2" wind slab that was fairly saturated with water and was weird to ski -- at best...
Apron is fully isothermal and it is possible to ski to and from the lower TH.
