The existence of low-elevation populations of Neotoma cinera in the northern Bonneville Basin shows either that these mammals can survive thousands of years in xeric habitats or that they can move across xeric lowlands far more readily than has been appreciated, or both. Current models of Great Basin small mammal biogeography are far too static to encompass properly the interaction of the wide range of geographical and biological variability that has produced the modern distribution of those mammals that have, for several decades, been treated as "montane" within the Great Basin.
