The type of geologic materials, and their hydrogeologic characteristics, is a major factor in determining the availablieity and sustainablility of a groundwater resource. The hydrogeologic characteristics of the major hydrogeologic units displayed in this layer include type (matrix, fracture-dominated, karst, or a combination of these) and magnitude of permeability (high, moderate, low). This layer should be used in conjunction with HydroGeologic_Sediments layer which contains unconsolidated quaternary deposits.Created by Integral Consulting Inc. and Heath Hydrology Inc. using USGS and Colorado Geological Survey data.
