Realistic Greyscale Topographical Map of Mountainous Terrain with Elevation Variations and Textures

Create a greyscale map that represents terrain with various heights. Include distinct plateaus and a deep valley. Use shadowing and texture to show elevation differences. Maintain a monochromatic color scheme, focusing on white, grey, and black. Peaks should be prominent and valleys contrast with lower elevation. Ensure a three-dimensional appearance with realistic contours and slopes, Greyscale topographical map shows mountainous terrain. Distinct plateaus and a deep valley visible. Textured elevation differences represented by shadows. Monochromatic color scheme of white grey and black. Prominent peaks and contrasting valleys. Realistic three-dimensional contours and slopes emphasized
