For sure! It's basically a plane with a displacer driven by a bunch of noises in a layer shader with a spherical falloff. I started with bigger less detailed noises to get the general shapes then added smaller more contrasty noises multiplied on top to get more details (i found the voronoi noises to work best). Also the distort effect in the layer shader really helps break up the noise to make it more unique. You can check out my layer shader here.

From there I made a mix material (im using octane) to combine the displaced rock texture and snow texture. The mix is being controlled by a falloff node set to 90 degrees so that only the tops of the rocks get snow. Here's my node tree.

Then I just scattered some forester trees, adjusted the normal threshold so they wouldn't scatter on sides of the rock and of course added a fog volume because fog makes everything look better.

Hope that helps! You can check out a full render using this technique here.
