Such a wash really isn't a problem. Pretty simple, actually. 30mph and fly across. Seriously. Any wash to narrow to ride in and out can be jumped. The right hand side looks not to steep, assuming from the direction the bikes are facing that is the exit side.
If you're not up for that, or terrain does not allow sufficient speed, approach nearly parallel to the edge very slowly and pop the front end up as it runs out of real estate, just enough the bike stays level, grab the clutch and both brakes between when the rear wheel rolls off the drop and when it touches the bottom. You'll come to an immediate complete stop with compressed suspension. As the suspension rebounds, shift body weight aft and towards the exit side while yanking hard on the handlebars to pull the front end up and around to the exit direction. Once the front tire is pointed the right direction, shift weight forward and go hard. It'll all be over in about 3 seconds, and you never have to take your feet off the pegs.
The key is using spring rebound and body weight together to toss the bike around.
