Then you can stroke the path you made with the pen tool, and the hachures should appear, following the mountain shape. I'd demonstrate, but my computer and Photoshop are in another state at the moment. I can't remember exactly which settings you'll need to adjust, but play with the brushes window for a while, and you should see what you need.
