Fallen giant sequoias, such as the one on the left near Log Meadow (group LMN), enabled us to obtain samples near the original ground level. Swetnam is shown standing in a fire scar cavity cutting a section from a buttress growing around the fire scars. In the middle photo, Swetnam and Baisan are inserting a 2 meter length chain saw bar into a snag (CMC3) to remove a radial section. This tree had innermost and outermost dates of 1240 B.C.E. (Before Common Era) and 1844 C.E., respectively. The photo on the right shows R. Scott Anderson and colleagues extracting a core sample from a wet meadow in a sequoia grove for pollen and charcoal studies.
