I'm just trying to help out. And, yes, I absolutely agree that reopening the normal route of the PCT is the absolute best option. The San Bernardino National Forest is one of the better run National Forests in the area (relatively speaking) for whatever reason, so let's hope they get it together in time for the PCT Class of 2016 to pass through.
A few problems with your bypass:
1. You're still cutting through the
Lake Fire Closure Area. Township 1 South, Range 2 East, Sections 17 and 18 are part of the fire closure. If you're going to blow of the fire closure, that's your business, but you may as well take the regular route of the PCT in that case.
2. Many of the trails shown in and around Township 1 South, Range 2 East, Section 20 no longer exist. Indeed the trail shown going from Middle Fork Jump Off to Bighorn Mountain and from there crossing the tarn to join the Vivian Creek Trail has never existed in the history of the world. I don't know what that particular cartographer was thinking; perhaps he was smoking crack? I've been hiking up there since the 1960's and my dad since the 1940's and my grandfather since the 1920's. There is not now nor has there ever been a trail there.
3. That area is far more rugged than you may fully realize. As for going from the Middle Fork of the Whitewater River to the Vivian Creek Trail, it can be done; indeed I know people who have done it -- about 3 parties in the history of the Wilderness. Maybe a couple of others I don't know about, but making passage through that rugged, brushy area is no trivial feat. Unless you're really an exceptional athlete, you might want to think twice. Up to you of course. If you can do it, it would be an AWESOME accomplishment, and I will be the first to congratulate you. Indeed, if you hike all the way from Mexico and succeed in getting from Whitewater to Vivian Creek by a route through the wilderness, I'm good for a steak dinner and a beer at any restaurant in the vicinity of the PCT in the San Bernardino Mountains (probably Big Bear or Angelus Oaks). I don't mean to discourage you, but it is really something that you'd want to think through.
Good luck on the trail,
