Oh, that's really simple:

#declare T_ARCTIC_01 =
texture{
    slope -z
    texture_map{   
      [0.1 T_SnowA ] //flatter 
      [0.1 T_Rock ]  //steeper
    }
}

in left handed system, you would use slope y.

I use different settings for  T_SnowA and T_Rock for w/o radiosity and changing
the values quite often, good values are also dependant on the lighting
situation. 

one example (i think i used this for the radiosity version):

#declare T_SnowA = 
texture {
   pigment { rgb 1 }   
   finish {             
      ambient 0.0
      diffuse 0.6 
      specular 0.3              
      roughness 0.6             
      brilliance 0.4
   }
}
