I climbed there in the early to mid 80's. Several old aid lines existed and we put in several short toproped routes and one lead line up near the left shoulder (right of prominent mossy chimney). Also on the bottom right toe of the formation we put up a cool as hell 5.10 flared chimney, "Binkleys closet of Anxieties".
Other than what I did, there was a bit of route activity in the late 80's near the aforementioned left shoulder area with several harder bolted routes going in. There is route info in the original Little Si guild book. 'circa late 80's
