A nickname for the vicious death trap which is the Postenkill Gorge, in Troy, NY. A natural waterfall on the Postenkill creek, it seems to subsist on people who don't know that you should not try to climb wet, loose shale without equipment and training (perhaps not even then).
Like flypaper, the Gorge deviously lures multitudes of RPI students and other locals each summer into its gaping maw, requiring emergency services to come and perform various daring rescues.
