I believe the problem is that the geometry itself, being that an heightfield, is already stretched in those areas.

Thank you, And! The geometry isn't stretched but the uvs are. It was converted to vdb and then to polygons polyreduced.
The video link you provided is very useful, it gives me some other ideas for my project.

This is pretty rough, but might work in your case.

The trick you provided, mestela, looks pretty cool! I'll try to remember it.
It does give me the stretched uvs as I asked but the problem I've found with this solution is that
it gives me some stray small islands of stretched uvs and it's hard to filter them out using the threshold.

But it reminded me that there is a heightfield mask by feature that lets you select slopes by angle.
So I've ended up transferring the mask attribute to my new mesh and creating a group from that.

I still had to add plenty of vertical seams as the slopes were all the way around the mountain.
The result isn't perfect but it's a lot better than before and might be just fine.

Thank you, Guys!
