thats actually a pretty normal drop,they have strict minimums too.but topography can make some drops look insane.ive seen DC 4s,6s and even the Dc 7s erikson now flys well below the canyon rim here where i live,its about 1200 ft deep give or take in some places,awesome to see is the S2's dropping straight down the canyon wall making the drop,then turning hard left and flying out up canyon (due to winds)...living in the northern california mountains can be thrilling at times..lol
