"After four miles you come to one of two possible starting areas. The first is the unmarked road on your right (42N24A) that is blocked off to motor vehicle traffic....." This road is now open and is an approved Forest Service route. "From the corner of of 42N24 and 24A (N41.53751/W122.12469) you can walk down 24A about a 1/3 of a mile to a wide spot in the road on your left, there you will see an old jeep trail (N41.53914/W122.13411) heading south toward Whaleback's northern shoulder." You can now drive out the 24A. With care and a high clearance 4WD you can drive part way up the jeep road, to N41.53668/W122.13448. This is private timberland so it's not subject to Forest Service travel management rules. Park next to some huge slash piles and walk from here. The area has been logged and so once you leave the jeep road and head south up the hill, there is a lot of slash and blowdown on the ground, but once you leave the private land and get back on Forest Service (look for the red blazed trees that mark the boundary), the ground clears up nicely and from there it is a pretty easy but steep hike.
