Hello all,
   I am looking for delta-18O (or delta-D) values for the Colorado River
above Lake Powell. I am particularly interested in the snow-melt signature,
but will take anything I can get. Data from the Green, Platte, Uncompahgre,
Arkansas, or upper Rio Grande would also be useful. Any references or
citable data would be greatly appreciated.
  If anyone out there has a nice set of unevaporated water samples from the
Colorado, I would be happy to measure them and share the data.

Many thanks,
David Dettman
