Sorry, haven't been around here for a bit. I was reading bill-e-g's post, thinking, yeah I'd like to so see this GPS track, and then I see he mentions me.
Maybe the track comes from this image:

Yep, that looks pretty accurate - the various routes that wander - take your pick.
Here's another good map:

To follow the long route (not the summer shortcut), take the north fork at the LYV split, go about 100 yards looking up to the left. The trail is easy to follow all the way past Lost Lake. There you hit the slabs/talus and cairn hell. It's tempting to follow a set that stay low, curling west, but later you will pay for it. Or you can head straight up, but don't go too far - another set of cairns mark the approaches to HD's south face routes. I'd aim like this: go about 3/4 of the way up the right side of the slabs until you find the easiest way across, which looks like this:

Once you past that stretch it's just a slog.
A couple of weeks back we were looking at LeConte Gully, just north of Grizzly Peak. It was a little too wet/slippery for us to finish and chossy all the way. But I want to try again when it's dry, it could be a fun and spicy shortcut. Apparently that was used as an approach BITD.
