Not sure of the north face, but walk around to the east and you should find a route that's about 3 going up, a 4 coming down (strange, but we thought it deserved a dual rating). Take a rope, a biner, and a big sling for the downclimb and you should be OK. The 'summit block' height isn't that high from the plateau LeConte shares with Mallory.
(This is info from mid-1990s, but I wouldn't think the geology up there has changed that much in 15 years.
