 Sand Hills is derived from newly obtained luminescence ages. Prior to development of the
 UNL lab, Geosciences faculty collaborated with colleagues from other institutions who spe­

 thus raising our research productivity as well as our national and international visibility.

 with Goble primarily in charge of lab operations. Other UNL faculty that will benefit directly
 from the lab include Dave Loope, Joe Mason, and Jim Swinehart. Several graduate students in
