The Advanced Viewer is a tool for visualizing and discovering spatial data in San Miguel County Colorado. This application is for users who need a complete web-GIS interface and many tools. Designed for use on a desktop computer. Includes the ability to add layers, alter layer appearance, generate property reports, find properties using many search methods, mark up the map with custom graphics, and print to a variety of paper sizes and image formats. Also includes an interface for viewing oblique imagery (Pictometry) in a separate window. Training videos will be made available.

The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads Shapefile includes all features within the MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB tha begin with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

These line shapefiles trace apparent topographic and air-photo lineaments in various counties in Colorado. It was made in order to identify possible fault and fracture systems that might be conduits for geothermal fluids, as part of a DOE reconnaissance geothermal exploration program.

Geothermal fluids commonly utilize fault and fractures in competent rocks as conduits for fluid flow. Geothermal exploration involves finding areas of high near-surface temperature gradients, along with a suitable "plumbing system" that can provide the necessary permeability. Geothermal power plants can sometimes be built where temperature and flow rates are high.

This line shapefile is an attempt to use desktop GIS to delineate possible faults and fracture orientations and locations in highly prospective areas prior to an initial site visit. Geochemical sampling and geologic mapping could then be centered around these possible faults and fractures.

To do this, georeferenced topographic maps and aerial photographs were utilized in an existing GIS, using ESRI ArcMap 10.0 software. The USA_Topo_Maps and World_Imagery map layers were chosen from the GIS Server at server.arcgisonline.com, using a UTM Zone 13 NAD27 projection. This line shapefile was then constructed over that which appeared to be through-going structural lineaments in both the aerial photographs and topographic layers, taking care to avoid manmade features such as roads, fence lines, and utility right-of-ways. Still, it is unknown what actual features these lineaments, if they exist, represent.

Although the shapefiles are arranged by county, not all areas within any county have been examined for lineaments. Work was focused on either satellite thermal infrared anomalies, known hot springs or wells, or other evidence of geothermal systems. Finally, lineaments may be displaced somewhat from their actual location, due to such factors as shadow effects with low sun angles in the aerial photographs.

Credits: These lineament shapefile was created by Geothermal Development Associates, as part of a geothermal geologic reconnaissance performed by Flint Geothermal, LLC, of Denver Colorado.

Use Limitation: These shapefiles were constructed as an aid to geothermal exploration in preparation for a site visit for field checking. We make no claims as to the existence of the lineaments, their location, orientation, and/or nature. San Miguel County Lineaments. Projection Information: UTM Zone 13 NAD 27 projection

This dataset contains several memos describing geothermal targets outlined by Flint personnel in Colorado. Phase 1 involved an ASTER and LANDSAT thermal infrared imagery assessment conducted by CIRES of the University of Colorado, which identified areas of warm ground that might indicate geothermal heating. CIRES used the thermal ground anomalies, together with other GIS layers, to come up with a set of areas ("polygons") having high geothermal potential.

This was followed by a "ground truthing" or site assessment by Geothermal Development Associates of Reno Nevada, during the summer and fall of 2011. Of the many areas targeted and visited, several stood out for their overall geothermal potential.

In the first memo, "Colorado Targets", GDA's Richard "Rick" Zehner describes the geothermal geology of the following properties, which were deemed to have the highest geothermal potential: 1. Routt (aka Strawberry Park) Hot Springs in Routt County; 2. Rico area, Delores County; 3. Pagosa Springs, Archuleta County; 4. San Luis Valley, Alamosa and Conejos Counties; 5. Lemon Hot Springs, San Miguel County

The second memo, "Comments on Rick's Report", from CIRES investigators, is a critical evaluation of Zehner's memo, in relation to CIRES' satellite thermal anomaly maps.

The third memo, "Penrose Area" is a detailed description of preliminary investigations into the geothermal potential of that area in Fremont County.
