Start to the right of the bolted Brownies in the Basin and go up a somewhat hard to protect (only the first 15 or so feet) crack and continue up for another 50ish feet aiming for the slight roof/bulge with several vertical cracks in it. When you get there step left, plug a two inch piece and enjoy a few perfect hand and fist jams (5.9 I think) that leads up to the pillar and belay point for Northwest Corner. Belay here or keep cruising to the top with the NW Corner finish.
Not sure what you mean here, "Brownies..." is the bolt route (or I should say, before the bolts were placed it was called Brownies....) and West Cracks I believe is the steep hand and finger cracks to the right of Brownies. Cracks deposit you on top of the pillar as for NW Corner.

An excellent alternative is to stick to the fist crack that wraps around to the right and then up. This gets you behind this small buttress eventually and at the start of West Dihedral. This crack is more of a big flake at one point and kind of spits you out to the right with bad feet for a 5.9ish move. Plug a good cam and commit to the jams and you get above to good holds. Keep on up and end up on a large ledge below the roof with a bolted route on the right. Either add a pitch up the offwidth dihedral to the left and join Northwest Corner or traverse on easy ground at the ledge level and walk off. Place gear on the traverse or not.
