Longevity and progressive abandonment of the Rocky Flats surface, Front Range, Colorado

Abstract

The AA. focus on an extensive remnants of the Rocky Flats surface between Golden and Boulder, Colorado, and use in situ-produced Be 10 and Al 26 concentrations in terrace alluvium to constrain the Quaternary history of this surface. Numerical modeling of isotope concentration depth profiles suggests that individual sites have experienced multiple resurfacing events. Fluvial incision into these surfaces appears therefore to progress headward in response to downcutting of the South Platte River. The complex ages of these surfaces call into question any correlation of such surfaces based solely on their elevation above the modern channel
