Been a cold week so glue has been taking longer than I would like to dry but I have managed to get the board to the next stage in the build.
First two steps where to cover some of the dips with scenic cement applied with a brush and then sprinkle the WS snow (using a spoon) onto the wet patches and let dry. This helps cover up some of the blue showing through and starts to add the texture. Even though I started this bit on Sunday and it took till Friday to dry solid I have not gotten any pictures of these steps

The reason for using the cement rather than glue is that I do not want the dips to be completely filled in by the glue / snow mix now - just smoothed out slightly. Using the wood glue / pva has a habit of lumping the snow mix together in small clumps even if it is watered down whereas the cement has something in it to remove the surface tension and the result is a softer / smoother covering than I can get with PVA and water mixed together. It may be due to the very hard water (high calcium) we have here.
When the glue was dry any loose snow is blown off (do not wear a dark blue hoodie at this point) and the whole board sprayed with scenic cement using a fine spray and then the snow sprinkled on in a reasonably thick coat straight from the plastic bottle (using the holes not the pour slot).
As the snow remains on the surface of the board I get a result like this close up:
with the board overall now looking like:
You may be worried by the texture - as this is for skirmish I am not concerned about troop trays or sliding figures and find after another couple of coats of cement sprayed on these are solid. Also remember each 'flake' is less that 1mm in size

Turns out that the black basalt rocks I thought about using would have been a better idea than the white ones (well more accurate to Earth) but some of them are translucent and look rather cool:
I know folks have been commenting on the water (marker pen and all) but now the light snow is on the tops I am really happy with the result:
The next stages are:
To sort out the edging - I'm thinking a smooth layer of flex paste and light sanding to hide the pink / white / glue mix:
As for scatter materials I am thinking:
- Bare trees dusted in snow
- Dead trees with snow covering most of them
- A wooden bridge over the crack
- Bits of the ice sculpture on there way to me (big thanks to Chris Palmer for sending me a couple -TMP Link
- Little piles of rocks
- Ice sheet
- Bones - I have a few dino bones around so these will get cut up
I am avoiding buildings for now as I have a great reference on village life and may end up building another board next to this housing a small hamlet rather than the odd igloo.
Any one else got any ideas?
