PANAMINT LAKE WASH DELTAS
The rivers flow seldom in Panamint Valley, usually in the late winter and early spring, and only during the brief period in the aftermaths of rare rainstorms, coming and going within a few hours or days. Only then do they advance their carving journeys down to Panamint Lake, eroding the sediments of previous rivers, and exposing a wide range of minerals and rock.
Here is the basic plan of local terrain creation. The idea is to let water do the sculpting. We rely on local features, such as the ramps and hills around the immediate area, to guide some washes. Further away, we use satellite data to confirm the location, direction, and splitting/reconnection profiles the washes take as they proceed downhill. This particular area is about a mile from the lake's western edge, and the washes are beginning to spread out as the slope flattens.
The washes are flat-bottomed, so we use the terrain lifting tool to raise up anything that isn't a wash, creating islands, and giving the local desert a wild character, and a feel for some depth.
There are rocks everywhere, like some endless quarry, of every color and description. The default ground texture is an endless sheet of stones and pebbles. The wash bottoms came from pictures of washes from the area itself. As the route progresses, we use variations of color on these basic textures to capture the local geological feel. Each area is different, especially as height increases.
We then glaze the tops of each island with a mix of desert flat and more rocks. The desert flat is the tan stuff speckled with dots which came from a picture taken not far from this location. There is a browner version of it in the extreme foreground. We're letting the terrain sculpting bury the highway because there is a special tool for making cuts relative to a flat surface.
Must be spring! The rocks and plants come from great sheets spread like carpets over the terrain. We tell it what plants and rocks we want, and the simulation creates a random arrangement across the entire sheet. We give it a density and, scaling and rotation and it does the job of placing the objects. We add a gravel bed for the highway, now cleared of debris.
