I would add some water below this ice or a fine, small layer of ice here and there as if the wind blew snow over the ground and in some grooves it stuck.
I'd love to do that but mixing snow, ice and ground materials in a convincing way is yet beyond my abilities I fear.
I tried an area with more reflection for a wet look but those bright reflections started to compete with the ice, diminishing the aesthetic effect.
Initially I wanted to put something on a rock and chose a PBR material with displacement map, only it looks like dirt instead, maybe because of an adequate PBR shader missing or the low sun position.

I‘ve planned to setup example scenes and write a short what-to-consider for CPU BiDir, Metropolis and Filters settings to get quite fast renders for caustics and/or scattering volumes, with a reasonable noise.
That will come handy, looking forward to it!
