The theme of the 2004 GSA Annual Meeting and Exposition, “Geoscience in a Changing World,” covers both new and traditional areas of the earth sciences. The Front Range of the Rocky Mountains and the High Plains preserve an outstanding record of geological processes from Precambrian through Quaternary times, and thus serve as excellent educational exhibits for the meeting. With energy and mineral resources, geological hazards, water issues, geoarchaeological sites, and famous dinosaur fossil sites, the Front Range and adjacent High Plains region provide ample opportunities for field trips focusing on our changing world. The chapters in this field guide all contain technical content as well as a field trip log describing field trip routes and stops. Of the 25 field trips offered at the Meeting, 14 are described in this guidebook, covering a wide variety of geoscience disciplines, with chapters on tectonics (Precambrian and Laramide), stratigraphy and paleoenvironments (e.g., early Paleozoic environments, Jurassic eolian environments, the K-T boundary, the famous Oligocene Florissant fossil beds), economic deposits (coal and molybdenum), geological hazards, and geoarchaeology.

This is a well-illustrated treatment of and guide to all the fossil and present-day species of butterflies in one of the richest areas in North America for butterfly diversity and study. For much of the year, the meadows, forests, and grassy slopes of the Florissant region of central Colorado are alive with butterflies - nearly 100 species of these fascinating and beautiful creatures. Many of them have unusual life histories: the larvae (caterpillars) of one species take two years to mature; others develop close associations with ants; and the adults of some species live only a few days, whereas others survive for months in winter hibernation. Central Colorado is also the site of the florissant Fossil Beds National Monument, which has yielded 12 of the 44 known species of butterfly fossils in the world. To find fossils of these delicate-winged creatures in such a perfect state of preservation is one of the wonders of nature, since the fossils have endured 35 million years of geologic activity, erosion, and climate change. Remarkably, most of the fossil species are closely related to various present-day species.
