I started at the West Bluff lot and hiked to the Reserve which is maybe halfway along the green line (could be wrong). From the reserve I forged east along the top of several talus fields, dropping into most of them way before I needed to. Unlike the clean talus of the West and East bluffs, most of the talus I encountered was dirty, unstable and a real pain in the ass. The Ejaculator is a decent trip down so I'd recommend staying higher (more south) and in the woods. You can use the lake as your guide as you have a sense of where it is the whole time. You can start looking for the Ejaculator on your left once you've passed the eastern edge of the lake and the south shore parking lots are due north of you.
To get down from the ejaculator I went downhill and trended slightly left coming out on South Shore drive just to the east of the southern most lot of the south shore. If you were to reverse this trip you could walk east out the southeast corner of this lot and look for a drainage pipe on your right. From there start questing up into the woods in a southeasterly direction. You won't be able to see the Ejaculator until you are all the way on top of the bluff. It wasn't fun coming down so I don't imagine it's too fun going up...”
