I can't be sure, but i doubt it. Those mountains are just a shade drawn on one side of the montains. I mean there may be some brushes imitating this, but i dont think you can make a nice long moutain ranges using those. The best "workaround" if you are not good at drawing from scratch, is to turn on bevel and emboss option and just draw lines in white. Bevel and emboss will apply a shade on one side and you will have similar effect. You can then play with B&E options to make the more smooth or sharp.
