Dirk... Note that gps locations and elevations don't work well in the Lone Pine Creek drainage -- the GPS satellites that are low on the horizon are out of reach due to the high mountain ridges. So GPS readings can be way off.

Now, if you're determined, then go here and pick up as much info as possible: Mountaineers Route info links within... Much if the info is old--broken links, etc, but what is there is well worth reading.

A note about the MR Notch: View these two pictures from last year, May. The first one is looking eastward toward the Notch, from the Easy(deadly) walk-off. Second one is looking westward from the Notch, tracks following the walk-off. The Final 400 is immediately to the left not in the picture.
