Introduction:

This data repository presents the compilation of evidence and criteria-referenced analysis of twenty transverse drainages in the southwestern U.S.A..  Sites were selected from the major physiographic provinces, six from the Basin and Range, seven from the Transition Zone, and seven from the Colorado Plateau.  The selection process and the methodology used to analyze these twenty sites are presented in the main text, which uses the same structure in site numbers and names.  The data repository is organized by physiographic province.  For each site there is a short description of the location; discussion of the evidence as it relates to the consideration of the four mechanisms antecedence, superimposition, overflow, and piracy; a table that compiles the evidence by their applicability to the transverse drainage criteria; and lastly, an image of the site from either the field or MicroDEM.
