I would be VERY surprised if that can't be massaged back....I've had nearly that bad on stock rims and never even worried about it...but that's probably at a point I would take it to a specialist. Shouldn't be a problem.

be thankful you weren't wearing Magnesium hoops....

...wonder what that hit would have done to carbon fiber rims?...

I could speculate, but I really don't have the knowledge of carbon rims properties to comment.

I'll just say I like metal that bends before breaking in areas like that....

Strangely i had the same thing happen last ride.Was time to give the wheels a polish and noticed a flat spot (not as bad as the pic) on one side of the rear rim.
Managed to get it back into shape using a plastic hammer,also thinking glad it is soft unlike Carbon Fibre or Magnesium.

That can fixed. There is a guy near me that does fantastic work
Not sure where you are, if there is something close to you, but
www.mcwheel does a great job.
Of course the other thing is you may be able to buy a used for about the same money.

I wonder if it would have been worse if it was between two spokes? :dunno

Don't think that the CF rims aren't as stong as aluminum rims.

Actually the best thing you can do to protect your rims might be to have a compliant suspension with good-flowing valves and light Dymag carbon fiber wheels, so that if you hit a boulder the wheel goes up over it instead of bending. Race Tech Gold Valves and the Dymag carbon fiber rims, and you would have no rim damage at all. Maybe spoke damage with the all-Cf ones though. The Dymag rims are really INCREDIBLY strong against forces in that direction, though not so strong against being squished from the sides in a wheel vise on a lift table, their strengths and weaknesses are very directional. The Dymag CF rims are exceptionally strong, which is one reason they have more rotational inertia than the BST Blackstone Tech CF wheels which have lighter rims and less weight out at the edge.

For instance, years ago when I (unfortunately) drove my old TLS into the broad side of a Jetta at speed, I didn't get to inspect it much before the ambulance came and before the bike was stolen by the city tow driver, but the front of the bike up to the engine was pretty much gone, forks and frame probably bent, the Dymag all-CF wheel spokes disintegrated and just exploded into leeetle teensie tiny pieces of CF all over the intersection (some of the CF fender pieces held together better 'cause I'd 'glassed the underside). Headlight, guages, upper fairing (TLS) all just gone completely. Heli Bars a mess. Fairing stay & windshield probably ripped off by my body. Thumb-brake master lever probalby what ripped down my belly and crotch 'till it poked a hole in my left ball-sack, etc. (and damn scary to find blood in your ejaculate even just once).

The bike was embedded deeply into the Jetta (behind his front wheel) still a little up in a stoppie-like posture embedded beyond the bike's gas tank, but after they pulled it out the carbon fiber rim (no longer having any spokes at all) was shoved right against the bike's front axle, rim embedded deep between the widely splayed brake discs, but still completely intact and holding air to the tire! No rim damage and tire didn't leak at all! Not a bend or a crack in the rim I could find with my one good unbroken arm LOL, certainly no hissing leaks. Those Dymag carbon fiber rims are WAY stronger than ANY other rim I've ever encountered, including the BST! At the bike show the Dymag rep lifted a CF rear wheel over his head and threw it down (with no tire) onto the concrete as hard as he could and it just bounced undamaged, and he did that all weekend long. The Marvic Cf wheels looked pretty strong too. And the hybrid Dymags with CF rim and the mag center are an even stronger combination. Though I must admit, the catastrophic failure of my CF spokes may have helped minimize the damage to the rims, like breaking your sacrificial clavicle prevents the breaking of your more critical neck. Come to think of it, amazing I didn't break my clavicle LOL. But the old 3-spoke Dymag all-CF rear wheels didn't have the best hub attachment either.
