Generally, filters designed for color film to "enhance" or slightly warm or shift the colors in the scene have very little effect on black-and-white film.
While the filter you refer to may make red rocks a bit more pronounced on color film, it will likely do very little, and maybe not even what you want, on black-and-white materials.
When I'm photographing in red rock country I am always confronted with the question of how I want to render the red rocks in relation to the rest of the scene. Sometimes, when the red rocks are slightly darker than other lighter sandstone rocks, such as in striated cliff walls, etc., then I may want to darken them. This would generally call for a green filter of some sort.
On the other hand, red-rock spires against a blue sky might want to be lightened a bit and the sky darkened a bit. This would call for an orange filter (or maybe yellow or red depending on the degree of contrast needed).
A polarizer with black-and-white film can be quite rewarding, since it can darken things with reflections on them appreciably. The effect is easily visible by looking through the filter. Just be aware that it is easy to overdo polarizing and that objects without reflections can often look dull and lifeless. (I guess a rock is lifeless, but you know what I mean...).
I'd recommend you do a bit of studying up on the usual colored filters for black-and-white and maybe acquire the basic ones: yellow, green orange, red, plus a polarizer. Then do some experiments with your red rocks. Take a shot with no filter and then all of the above.
You may find that even when using a rather strong filter, the effect on red rocks is very slight. Even though these rocks appear red to us, they are often of rather low color saturation and even a strong filter makes little change.
Good luck,
