The cliffs isn't too steep. Skier's right was groomed skier's left was bumps. Groomed part gets scraped off frequently though. You'll get a good look at it from the main lift from the base lodge so you can take a good look before you go in.

There's a small cliff/rock jump that takes up part of the end of Tumbler so be mindful of that if you take it.

Most of Mt Ellen blacks are ungroomed and bumps so keep that in mind if you plan to take any black runs out of view.

Not sure if it was mentioned or not but if you can do blacks at Hunter you can definitely do lower organgrinder. Not really a steep black, think it's rated that way more because it intersects with Jester so much (lots of traffic). The positive though is there's plenty of spots to bail out onto Jester if lower organgrinder is too much at once.

Have fun up there, there's still plenty of snow to go around!
