Any clues about what's going on in the mountains right at his shoulder (camera left)?

My best guess is that it has to do with the Nik filter I applied in PS (no. 24, Full Contrast).

 

Here is the original before the conversion (not as interesting, eh?):

And a crop pre-conversion:

I noticed it after I converted it but ignored it because I liked the rest of the image too much to bother with that small detail, heh. But then Rontography asked me what was up with it, so I thought I'd see if anybody has any ideas about why it looks like that.

It looks like the B&W conversion screwed up that smooth gradient.  I'd recommend doing the conversion twice, once as you've already done it, and once to preserve the edge details, then stack them and clone out the ugly part of the original conversion.

Had you done a selection with the mountains as the edge before processing at any stage?

Nope, no selections whatsoever.

I just asked because it's happened to me a couple of times and I could never figure out what happened.
But it's a really cool shot no matter what.

First off, great photo.  I'd spend 2 minutes with the clone tool and call it a fix, it's such a minor part of the image, but it is interesting.

It seems that the contrast gain is too high for the light haze over the mountains. You might also have a bit of coma aberration at the high contrast, but unsharp edge between sky and ground. It is, however easy to fix in PS. You use the same technique as with halos in a hdr, just make a layer without the sharpening applied and carefully mask out everything except for the correction itself. This usually looks better than the cloning tool.

Did you sharpen the image before you convert?  I've seen this as chromatic aberration from sharpening a bit too aggressively.

This phenomena is usually related to too much increasing or decreasing of the shadows/highlights sliders in Lightroom. Go back through your history of the original RAW photo and jump back a few steps to before you adjusted those sliders, convert it to black and white at that stage, and I bet it disappears. Tinkering with those sliders a lot may not show in all areas of the photo, or on the color version, but the effects are pronounced in mono.

Thanks, BW is usually one of my last steps, so I might have been introducing these issues as well.

It's always best not to have to adjust any Lightroom sliders too far from how the shot was originally taken.  The more you increase any of the sliders like contrast, sharpness, luminance, highlights, etc. the more prone you are to some sort of altered edges and awkward looking color and highlight separation.

Yeah, I have a shot I like that I took with my friend's A7, but i blew the highlights too bad in the background.  His flash wouldn't have been strong enough to compensate for exposing for the background and I didn't have much time to fumble with the unfamiliar camera to get the shot anyways.  I have some horrible things going on in the sky in the background.  I'll have to spend some time reworking this one, but the highlights are just too blown out.
