ouch!

When I first looked at the picture, I thought I saw a kickstand, which would
mean it is a posed picture. However, I think that dark line is his chain,
which means that this poor guy is flapping at both ends.

Is it my imagination, or is the top half of the headset going along
for the ride? That can't have ended well...

The guy's racing XC on a rigid fork and the steerer snapped, looks like.
That's insane.

Agreed. Double ouch.

It looks to me like a quill stem - what do others think?

So does that mean his steerer column separated somewhere in the threaded
section?

That's what I love about carbon steer tubes, but why did his chain
fall off at the same time?

I bet he reemed it out to fit a 22.2 mm stem in there 🙂

Look at his tires. The front is quite compressed and the rear is off
the ground. I assume he just same off a jump, which explains the stem
and the tires. I seem to recall my chain doing stupid things on jumps
with *mart mountain bikes as a kid, but someone with more experience
will need to confirm this theory.

That's not a carbon steerer tube. It's a threaded headset.

His chain didn't fall off. If you bothered to look at the picture with more
than a cursory glance, you'll notice that the chain is still wrapped around
the small chainring. As Paul H mentioned, it's post-jump, as is the
following photo I recently took with the same phenomenon present.

Um, when did old GT mountain bikes come with carbon steerer tubes?

Most importantly...

*the bottom 3 spokes on the front wheel are visibly BENT*

I guess this answers our spokes hanging vs. standing debate.

That's hardly the same thing. To me, it looks like the problem is at
the rear cluster- follow the line of the chain towards the rear. That
ain't normal.

There are many interesting things in this photo, which unfortunately is
too low resolution to make out the details. For example:

-what is the black line going from his back knee forward?
-what are the two black lines crossing his front tire, between the
stem and his lower hand?
-what is that thing that looks like a straddle cable and yoke in the
same region?

It's not clear at all that that is a threaded stem. The resolution just
isn't good enough, but for example, there appears to be a stack of
spacers at the bottom. I know of no threaded headset that looks
anything like that.

Then I take it you haven't seen too many dirt jump photos. The chain
inertia can easily pull the derailleur completely linear.

A straddle cable and yoke, most likely.

It looks like the locknut and cup. The diameter of the vertical portion of
the stem is such that it would not be large enough to clamp around the
steerer. I think it's threaded.

Possible scenario:

Rider falls forward onto bars.
Steering column snaps.
