600mm (2 foot) x 600mm x 40mm - Lightweight polystyrene terrain tile. Each tile features a 20mm deep embankment (for the main river section with a smaller stream joining it) with textured mud and grass embankments. The stream section of the tile is graduated to give a shallower aspect than the river. The river and stream features various areas of mud and rock bedding. Both the river and stream have various grey-blue shades for an authentic river and stream effect. Both the river and stream start and finish centrally on the tile edges to allow for sympathetic "joining" to other river sections. Each of these boards can be used in conjunction with the various other tiles in the range.
