Short summary
This paper summarizes a workshop held in Parker, AZ, USA, to discuss planned scientific drilling in the Miocene(?) or early Pliocene Bouse Formation, a controversial deposit (of lacustrine, marine, or some hybrid origin) found in the lower Colorado River valley. The drilling project is intended to address this controversy as well as shed light on Pliocene climates of southwestern North America during an important period of past climate change.
