It was 19 meters....just under 60ft. If they reshaped the takeoff and made it poppier, that easily could have been taken 80ft. plus. Watch the edits again, and you'll see that a few ladies sent that thing deep as shit.
Would it have been optimal for a male big-air? No, not at all, but that shit wasn't much smaller—if at all—than the city/scaffold big-airs. It would've worked well enough that people could've done some ill shit and gotten footy, that's for sure.
This is all assuming of course that the gal's jump wasn't plowed immediately following...which I assume it probably was...
