U.S. GEOLOGICAL SURVEY 
Introduction 

The data reported herein was tabulated from field notes into a spreadsheet. The data was 

collected during autumn of 1999 as part of a U.S. Geological Survey, Geologic Division, 

Postdoctoral Fellowship to J.S. Caine. The data was used to characterize fracture networks and 

fault zones and their impact on the hydrogeology of crystalline, Precambrian rocks of the 

Colorado Rocky Mountain Front Range just west of Denver, Colorado (Figure 1). As part of the 

characterization effort the data were used to numerically simulate fracture network hydraulic 

properties such as fracture porosity and permeability. Data from the Harrington, Nobel, and 

Green localities formed the basis for a Master's thesis by Stephanie Tomusiak working with 

Shemin Ge at the University of Colorado, Boulder. Additionally, numerous field assistant 

volunteers helped collect and record the data and their names appear throughout the body of the 

data. The reader is referred to existing and future publications for a full explanation and 

interpretation of this characterization and modeling study (Caine, 2000; Char, 2000; Tomusiak 

and others, 2000; Caine, 2001a and 2001b). 

Figure 1: Simplified geologic map of the Turkey Creek Watershed showing fracture network data-collection localities. 

Individual rock types have been grouped together in hydrologically significant units and structures. The US40 Fault 

Zone locality is outside of the watershed and is not shown in its correct position. Poles to all data collected at each 

locality are shown in equal area projections (n is the number of fracture orientation measurements collected at each 

locality). Modified from Sheridan and others, 1972; Bryant and others, 1973; Scott, 1972; and Bryant, 1974; Char, 2000.

Collection of Fracture Network Data in the Field 

Overview 

Fracture network data was collected in the Turkey Creek Watershed (TCW) to better 

characterize fracture network and fault-related hydraulic parameters and answer a few primary 

questions about this complex aquifer system: (1) How do fracture networks vary in individual 

lithologies? (2) How do fracture networks vary from one lithology to another? And (3) How do 

the variations in common and measurable fracture network parameters translate into numerically 

simulated hydraulic parameters such as fracture porosity and permeability? 

In practice, several approaches have been used to better characterize fracture network 

hydraulic parameters. These have included aquifer hydraulic tests and numerical modeling with 

discrete fracture network modeling schemes (Anna and Wallman, 1997; Jones and others, 1999); 

fracture network data collection from pavements and tunnels (Sweetkind and others, 1997); 

analysis of mineralized and altered fracture networks as indicators of the systematics of 

paleoflow in an aquifer (Taylor and others, 1999); borehole televiewer logging and flow 

metering (Paillet and Pedler, 1996); lineament analyses (Bryant and others, 1975); and 

environmental tracer analyses (Abelin and others, 1991). Many studies, however, only address 

one of two major components of the needed information for comprehensive groundwater 

resource evaluation in fractured rock at the watershed-scale (notable exceptions come from work 

at Mirror Lake, New Hampshire, Barton, 1996; Hsieh and Shapiro, 1996; Tiedeman and others, 

1998). These components include either field-based characterization of the geometric properties 

of fracture networks (typically from the borehole to outcrop to aerial photographic scales) or 

aquifer hydraulic testing to directly measure hydraulic parameters (typically at the scale of 

individual to multiple boreholes). The following describes the field data collection techniques 

used in the TCW study where aspects of both of these components are investigated. 

Outcrop Selection and Fracture Data Collection Along Scan Lines 

Color aerial photographs (at a scale of about 1:12,000) were used to select representative 

exposures of the dominant lithologic groups. Field inspection identified nine suitable localities. 

Natural outcrops with length scales of at least thirty meters and exposures of at least two near 

orthogonal faces were sought. By taking measurements on two near-orthogonal faces, fractures 

that were subparallel to one face were captured on the second face in an attempt to eliminate 

scanline orientation bias. Typically at least three and up to nine scan lines were analyzed at each 

of nine localities. Scan line sampling was used to collect the raw fracture network data (Priest, 

1993). A graduated tape, or “scan line” was stretched across the outcrop face and where 

practical, scan lines were set up at near right angles to major fracture sets to further avoid scan 

line-fracture set orientation bias. For each fracture that intersected the tape position (from which 

spacing and density are derived), orientation, trace length, termination, an estimate of aperture, 

degree and type of mineralization, shape, roughness, and any indicators of timing relationships 

(e.g. crosscutting and offset of other fracture sets) were recorded. These parameters form the 

basic fracture data from which Discrete Fracture Network models were constructed (to be 

reported elsewhere). Because the foliated rocks were folded and faulted any indication of 

structural position of each locality was also determined. Rock type, ‘unit’ contacts, 

compositional layering, foliations and a variety of lineations were also recorded at each locality. 

iii 
Data Format and Contact Information for Additional Copies 

The raw field data was entered into a spreadsheet computer program and formatted with all 

pertinent information regarding outcrop location, fracture scan line orientation and number, 

location geology, time, date, data measurer and recorder (listed below), assorted comments, 

samples and photographs taken. Measured data for each fracture encountered on a scan line was 

tabulated into individual data columns in the spreadsheet to facilitate a variety of calculations 

and transferability into other computer codes. In order to collect field data rapidly numerous 

abbreviations were used in the field notes. These are listed below.

Measurement Localities 

Location and elevation data is taken from U.S.G.S. topographic maps. UTM coordinates are 

in continental U.S. Zone 13. Latitude and longitude format is: degrees minutes seconds. Scan 

lines were collected from multiple elevations at each locality thus one representative value is 

reported for each locality.

COMMENTS / NOTES: Avg. spacing of fol || fracs ~ 4/m. They tend to tip out into steps and are quite short (1.5 to 2 m).

Fabric tends to 'come' and 'go', maybe forming compartments spaced on order of a few 10's of m's. Compartments ~ 10m wide?
