Many define three regions of the Trinity Alps by color as seen from the high summits of the central Alps. To the west is the extensive tract of land known as the Green Trinities, named not for a rock type but for the extensive swath of forest, perhaps the largest intact section of diversified forest in the greater Klamath Mountains. The Red Trinities includes lands of high ridgelines to the southeast that are defined by the characteristic igneous bedrock composed primarily of peridotite and interspersed with granite, which creates red-, brown-, and gray-colored summits. To the northeast, beyond the gash of Coffee Creek, are the granitic mountains of the White Trinities. The high, central Trinity Alps are also part of this group.

CLIMATE

Although the Klamath Mountains are much wetter than the Sacramento Valley and many other regions of Northern California, they are not nearly as wet as locations along the Northern California coast. Precipitation varies greatly in this relatively small area, from as much as 80 inches a year on some of the higher, west-facing slopes to less than 20 inches in some of the lower east-side canyons. Much of the precipitation occurs as either rain or snow during the winter months. However, thunderstorms are not uncommon during the summer.
