IMAGE DESCRIPTION: 


A majestic mountain rising out of a serene desert wilderness


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


Nothing fancy here.  The landscape is a basic heightfield made in Terrain Maker.
 The ground texture is a leopard pattern for the sand, a slope map for the snow
and mountain texture, and a gradient to vary the texture with height.

The atmosphere consists of a plane for the clouds and a simple fog for distance
fading.

The cacti are constructed of cylinders and spheres with branch positions
randomly perturbed and textured with a radial normal pattern.  The sagebrushes
are nested spheres made semi-transparent with the crackle pattern.  All
vegetation was placed randomly on the ground using MegaPOV's trace() function
on the heightfield.

Note: I experimented with the textures after producing the submitted image, and
could not recall exactly what the changes were, so the submitted code will not
exactly reproduce the submitted image, but it's pretty darn close.
