Big Sur Ventana/SilverPeak Trailmap
with Camps, Water Sources, and Points of Interest
for wilderness explorers

Trail & camp locations on many maps of the Big Sur Ventana & Silver Peak Wilderness Areas are incorrect!  This Big Sur Trailmap provides accurate trail and camp locations based on local knowledge (GPS'd), and also locally-known "use trails", non-obvious water sources, waterfalls, and other features in Big Sur wilderness areas and state parks.  Updated weekly from local reports. 

Wilderness hikers take note:      You cannot assume a wilderness trail will be passable or followable!   click

    Extreme drought - historically "perennial" water sources may not be reliable click

There will likely be Poison Oak no matter where you go, creek crossings can be difficult or even dangerous should there be a large rainfall event, some previously "perennial" water sources have been occasionally dry after successive drought years. 

Trailmap Notes:
Wilderness trail usability => trailmap line width :   Trails with VWA Trail Reports have differing widths for different segments depending upon the latest reported conditions, thicker meaning more usable.  (Based upon my parsing of latest reports, the widths range from 4 down to 1 for better to worse trail conditions.)  Please recognize that these ratings are rough as conditions may differ greatly along different sections of a trail - consult the VWA reports for detailed trail information, available as a link on a trail's info window popup.  When no reports are available, as for state park and use trails, the nominal widths are: trails = 3, usetrails = 2, "historic" trails = 1.  Ratings necessarily depend upon the latest reported conditions.  This is a "planning" feature so implemented only in the browser and GoogleEarth versions, not in single-page-printable and Garmin-format trailmaps.  Left-click on trail for a summary of its current condition and a link to the latest VWA trail report. 
Orange trail is a non-USFS "use trail"  (trail condition unknown)
Black trail/camp is "historic", i.e. no longer used
Tan campground has nearby public vehicular access (possibly 4-wheel-drive only)
Water information may be questionalbe during a severe drought year

General Browser Usage Notes:
Mouse left click on trail/camp/etc displays feature info
Mouse drag moves map
Mouse wheel zooms in/out at cursor
Icon position not exact if two icons overlap (as icons then offset for better display)
Can get missing segments or icons if zoom in/out too quickly, before line/point re-draw has time to complete
If map loses trails or becomes otherwise confused, use browser "Reload" button
If info "bubble" is displayed, zoom-in will include bubble site (useful for forcing zoom-in to include desired location)
For Browser Printing:   use browser "File->Print Preview", adjust if necessary (often "Landscape" is better than "Portrait"), then click "Print"[sometimes, e.g. in older browsers, you must select Page 1 only for "Portrait" orientation or Page 2 only for "Landscape" orientation] 
For Google Maps Printing:   its "Print" link provides another printing option. 
For One-Page-Printable Quadrangle Map Sections:   click
Note that available inkjet-printer-compatible synthetic papers are tear-resistant, grease-resistant, and water-resistant/proof (~50/90¢ per sheet) - one on-line source is Hi-Performance Papers

Gmap4-specific Usage Notes:
Backgrounds "Satellite", "Terrain", "USGS Topo", "MyTopo", and "Map" (ala Google Maps) are also available   (under top right "topo" menu)
The "MyTopo" quadrangle map background includes USFS trail and camp locations (but much is inaccurate!)  

GoogleEarth-specific Usage Notes:
Website trail/camp/etc GPX file downloads broken:   Google Earth has now added an internal browser, which instead of saving a GPX file download from this website as a normal browser would, will try (unsuccessfully!) to display it in GE, even if you try to defeat this behavior by enabling the "Show web results in external browser" option.  To download a trail/camp/etc GPX file, you must instead use one of the Big Sur Trailmap options which opens directly in a browser or use the GPX file download webpage.
Note that Google Earth can also display quadrangle topo maps as a background - for instructions on installing and using them see Adding Topographic Enhancements to Google Earth
You can "fly" Google Earth to many geographical features by typing a name such as "Cabezo Prieto" into the "Search/FlyTo" entry box.  Apparently this works for all features named on a USGS topo map.  Entering a partial name can also produce useful results, e.g. "Doolans Hole" is not in the database but will be found if entered because "Doolans Hole Creek" is in the database.  Adding ", CA" will limit the results to California.  And entering a latitude+longitude (in a format known to GE) will "fly" GE to that location. 
Note that while Google Earth will directly read GPX files, it also filters them by eliminating some points.  So if you download the tracklog from your GPS directly to Google Earth, the full detail of your track will not be displayed.  But GE does not filter Google-Earth-format files.  If you wish to see all recorded GPS points, you can use the free gpsBabel software to both download the tracklog from your GPS and convert it to a GE-format KMZ file for loading into GE.  Alternatively, you can use Garmin's BaseCamp or MapSource software to download the tracklog and then use gpsBabel to convert that file into a KMZ file.
