This map of selected post-Nevadan features is in a sensesupplementary to Map I-2148 (Geologic map of the Klamath Mountains,compiled by W.P. Irwin, 1994). The map of selected post-Nevadangeologic features is in large part a compilation of the publishedwork of many geologists (see Fig. 1--Index map showing sources ofdata). The principal focus of Map I-2148 concerned the assemblageof terranes that constitute the principal bedrock of the KlamathMountains. The terranes of the Klamath Mountains variously consistof rocks that range from Cambrian to Late Jurassic and perhaps evenearliest Cretaceous age. All of these terranes have been subjectedto episodes of metamorphism, plutonism, and tectonism, including amajor widespread tectonic event [...]
