As has been true BEFORE 9 JULY (Do it today.)! throughout the 21st century, optimizing your attendance at so many high-quality sessions will require some serious prioritizing (GSA's scheduling app for mobile devices helps). Of the 27 proposed pre- and post-meeting fieldtrips, all but three focus Division Awards - 2013 on Quaternary/Geomorphology topics of potential interest to QG&G members.

They leverage new observations against long-standing but incompatible models of how the Colorado River established a through- going passage to the Gulf of California. Observations are weighed against models until a compelling scenario of downstream-directed integration by basin filling and catastrophic spilling remains the only hypothesis standing.
