This product consists of maps and trail information. The information is in digital form in various formats. The primary purpose is to provide you with reasonably current trail information. That is we have updated the trail maps and provided recent trail information. There are more than 600 MB on the CD-ROM.
  • Updated Trail Information
The trails were surveyed from about 2004 to 2006 and the data stored in GPX format files. The file contains both point information (waypoints) and linear information (tracks that are drawn as trails). With a program that can open a GPX file, these points and "trails" can displayed against a background image such as a USGS topographic map or orthophoto. There are both free and pay for programs that can open GPX files.
  • USGS 1:24,000 Topographic Maps - Digital Raster Graphics
Seventeen USGS 1:24,000 topographic quadrangles are provided on the disk in the form of TIF files.  These are provided for a background image for the trail data provided in the GPX format.
  • Modified USGS 1:24,000 Topographic Maps
Those seventeen USGS 1:24,000 topographic quadrangles are also provided in another directory in the form of PNG (instead of TIF) image files. Some of these map image files have been modified with current trails so you don't need to use the  GPX formated files mentioned above.  They are provided for viewing with a WEB browser or other graphics program. In addition, WEB pages are provided that overlay icons on these maps for referencing pictures taken at the locations represented by the icons.
  • Visual Photographic Guide
Over 1,200 pictures are included on the CD-ROM to give you a visual description of the area and a taste of what the trail is like. The pictures can be accessed with a WEB browser via "hotspots" that are overlaid on the background maps where the picture was taken or they can be accessed from the GPX format file when opened with ExpertGPS. The picture waypoints have links to html files containing the pictures.
  • Data for GPS Receivers
Various programs are available that can open the GPX file and send the waypoints and tracks to GPS receivers. Exactly what data can be transferred depends on the program and the GPS receiver model. The tracks can form a "trail map" on the screen of the receiver. Symbols assigned to the waypoints are oriented to Garmin receivers.

  • Trail Data "Guide Book Style"
Trail data, including elevation profiles, and descriptions similar to guide books are provided in a WEB page form. Most of the trails on the map are covered and some combination of trails that make for possible hikes are also done. An example for the Mt. Bierstadt Trail follows:

Mt. Bierstadt Trail

Some of the trails covered are:

Abyss Trail (Scott Gomer Creek), Beartrack Lakes Trail, Beaver Meadows Trail, Burning Bear Trail, Captain Mountain Trail, Chicago Lakes Trail, Chief Mountain Trail, Cub Creek Trail, Gibson Lake Trail, Goliath Natural Area, Grass Creek Trail, Grays Peak, Hells Hole Trail, Indian Creek Trail, Lincoln Lake Trail, Lost Creek Trail, Maxwell Falls, Meridian Trail, Mt. Bierstadt, Mt. Evans, Resthouse Meadows Trail, Rosalie Trail, Shelf Lake Trail, Silver Dollar Lake and Murray Lake, South Chicago Creek Trail, South Park Trail, Summit Lake Trail, Tanglewood Creek Trail, Three Mile Creek Trail, Torreys Peak
  • USGS 1:24,000 Topographic Quadrangles
Bailey, Shawnee, Mt Logan, Jefferson, Boreas Pass, Conifer, Meridian Hill, Harris, Park, Mt Evans, Montezuma, Keystone, Evergreen, Squaw Pass, Idaho Springs, Georgetown, Grays Peak, Loveland Pass

Some of the outlying quadrangles have not been modified because any trails that appear on them were not surveyed. They are included for reference - you might want to know the name of the peaks you can see from the trails that are included.

Some other quadrangles only had current roads drawn on them that you might use to get to the trailheads. The roads that are mapped include elevation data in the GPX file so programs that can show elevation profiles can display the profile of the roads. If you are planning a bicycle ride on the roads covered, the elevation profiles may be of interest to you.

The topographic map files that were not modified with trails have been squared off so multiple ones can be loaded at one time.  However, note that many software programs cannot load more than one map image file at one time. Otherwise, these files have not been modified so they can provide a background image for the trail data provided in GPX format.
  • Garmin GPS Receivers
Some newer Garmin receivers support "POIs".  A "poi.gpi" file is provided on the disk containing most of the waypoints. Another directory (folder) contains a file to help the user turn the data into a Garmin map for use with their mapping receivers. The user needs a program available on the Internet to accomplish the conversion.
