Geometric Data
Colorado Rockies Map Map of the Colorado Rockies showing three versions of detailed maps:
     ♦ overview map of the entire study area
     ♦ 16 times enlargement for legible labels
     ♦ alphabetical list of detailed maps.

All three versions are linked to GIS colorcoded topographic contour maps; further linked to associated GIS profiles showing heights of terraces and pediments above floodplains. These maps and profiles are the geometric results of this study. Conclusions were derived from geometry shown by links from this menu.
Tabular Data
Surfaces from This Study This table summarizes heights of terraces and pediments above floodplains and provides a basis for tables of statistics. The table is organized by control point number and shows latitude and longitude of each control point; the detailed map it is on (see Colorado Rockies Map); names of each profile shown on the map; and representative distances above floodplains for up to 5 levels of terraces and pediments derived from profiles. Average of these reprenative distances are designated as Representative Values for N control points (Table 1), imported to GIS to make contour plots of four terraces heights above floodplains.
Surfaces from References Table of unconsolidated deposits from 150 maps and 22 reports freely available on the internet, includes units, ages, dates, dating methods used, and two columns of glacial terms. Organized by senior author. Translation available between map codes and senior author for comparison of this table to the Correlation Table which is organized by map codes and contains heights above floodplains from references.
Correlation Table Table comparing heights of surfaces above floodplains from the literature and this report and reaching a conclusion that this report and references are mapping the same surfaces though assigning different ages (see Correlation Chart). This table is organized by map codes; translation available between map codes and senior author of reference maps.
Correlation Chart Ages of surfaces or associated deposits from more than 170 references. The chart is scaled by years for the last 1.8 million years with corresponding Marine Isotope Stages, and graph of potential glacial lengths. Authors' geologic units (e.g. Qal) are plotted in absolute years based on stratigraphic nomenclature (e.g. late, middle Pleistocene) or glacial terms (e.g. Bull Lake or Illinoian). Organized by publication date, it shows persistent disagreement about ages of unconsolidated deposits in the Rocky Mountains.
