Prismatic Bkk horizons in the Mojave desert of Southern California.
The white colors in the Bkk horizon are calcium carbonate precipitating from the dry, arid conditions. The prisms about 1/2 a foot in width form from swelling when it does rain.

Majestic shifts in colors in Vermont. The Orange are from yellow beech and birch leaves mixed with red and orange maple leaves. The dark green on the other slope are conifers, such as spruce, pine, and balsam fir. Contrasting colors occur due to slope direction and soil parent material.
Eastern Hemlocks do exceedingly well in rocky soils with seasonal hydric conditions.
