Editor's Note
Sedimentary
rocks that form at the earth’s surface from sediments eroded from
pre-existing rock. The processes acting on the sediment at the
time of deposition are commonly reflected within the rocks they form
and preserved over long periods of geologic time. Clues to the
surface environment during deposition can also be surmised from the
sedimentary record. These rocks that form at the earth’s surface
offer nothing less than a snapshot of earth history, an opportunity to
study ancient climates, long eroded mountain ranges, and tread on
ancient landscapes lost to the relentless power of a changing planet
