Huh? Mittersill was an independent ski area that closed in 1984, and after that it was an unofficial "backcountry" area. Its trails weren't added to Cannon's trail count until it was incorporated into Cannon in 2009. Looking at old Mittersill maps, it looks like a lot of its trails didn't have names (kind of like the Banshee slopes, which only got names sometime in the 90s).
In terms of trail count inflation, the only potential examples I see, looking at current and previous trail maps, are:
- Renaming Middle/Lower Cannon between the end of Spookie and the top of Zoomer "Rock Garden", which is a terrible name for a ski trail (then again, Cannon also has "Global Warming Glade"). Originally, the divide was where the exit from the former Hong Kong lift joined.
- Renaming the lower part of Big Link to Missing Link, though that does make more sense.
- Short Fuse, although that does enable giving Lower Hardscrabble from the bottom of Cannonball a more accurate blue rating and lets you close the former but not the latter, and you probably couldn't have named it "Upper Lower Hardscrabble".
- Making Goat Path a trail again, that one disappeared from the map after Peabody Express went in and Middle Cannon was widened, and returned in 2014 even more useless than before. (I vaguely recall that the name "Rock Garden" originally applied, perhaps unofficially, to the far end of Goat Path.)
- Maybe Blue Ball, which got that name in 2008, being previously part of Lower Hardscrabble's runout.
- Oh, and I'll add MH Cut-Thru, another terrible name, which should have been just a continuation of Middle Hardscrabble. Does anyone even still use the original exit that you had to climb out of? (Which was there so you could get back to the tram before the Peabody Slopes were cut, and then took them 52 years to fix.)
I'm not counting giving names to previously unnamed trails (Lakeside, Banshee, Jasper's Hideaway, most of Mittersill) or making former liftlines into trails (Chute, Parkway, Profile, Banshee Liftline). And there's cases to be made for or against several short connectors that got names (David's Detour, Zoomalanche, Stinky St). (Wonder if Stinky St was named after a deceased Tramway base lodge cat, as were Spookie, Gremlin and Jasper's Hideaway.) Everything else that's increased the trail count is new trails or glades. Also, there is no "Upper Gremlin", although there could easily have been; Gremlin was extended up the Peabody Express liftline when that lift went in.
