A few further comments.
1. On his ascent of the Old Route, Fritz bushwacked up from the bottom, observed that the lower tier was "slabby and uninteresting," traversed the boulder field all the way to the Northern end of Millbrook, gained the Death Ledge from there, and in order to "to study the whole cliff more closely," traversed back to the Old Route start. On the way down, he walked South until it was possible to descend to the Death Ledge, which he then traversed all the way back North again, again looking for additional route possibilities, before reversing the bushwack to the car.
2. My comments about choss on the lower tier notwithstanding, Mim's post is accurate; there is some good rock at the far left end of the lower tier, underneath the portion of Millbrook known to the cognoscenti as The Beach.
