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

"www.ventanahiking.net" - info about recent unavailability  
"www.ventanahiking.net" was down for a 10 day period (April 2-11) due to repeated goDaddy forwarding failures.  I have now taken control myself so that URL now works and should continue to work in the future.  But I urge its current users to switch to the "real" URL "bigsurtrailmap.net" for future uses.   Full story

Many trail/camp locations on printed 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 (mostly GPS'd), and also locally-known "use trails", water sources, waterfalls, and other features in the Ventana and Silver Peak Wilderness areas and in Big Sur state parks.  It can be:  displayed in a web browser (with quadrangle map or shaded terrain or satellite image background) -OR- displayed in Google Earth software -OR- printed in page-sized quadrangle map sections -OR- loaded into a Garmin GPS.

Wilderness hikers take note:  you cannot assume that a wilderness trail will be passable and followable!  Trails may be blocked by brush or downfall and/or without apparent tread, especially for secondary trails and "use" trails.  Brush grows quickly in these wilderness areas, extensive falls of fire-damaged trees occur after strong winds, trails along the steep slopes are very subject to erosion, and maintenance is spotty.  Know before you go - you may be very glad you did!  I've encountered too many hikers who had no clue regarding the difficulties they were going to encounter, and who did not end up with the wilderness experience they had anticipated.  Where tread is sporadic and/or confusion with animal tracks possible, use of a GPS loaded with accurate trail data is recommended!  Left-clicking on a Trailmap line or icon displays an "information bubble" which for trails includes the latest summary of hiker-reported trail conditions and a link to the full VWA Trail Report (when available), as well as trail distance, cumulative elevation gain, and GPS data.

Trailmap Notes:
• Green trail/camp indicates verified location  (left-click on trail for its current condition)
• Yellow trail/camp indicates UNverified location  (left-click on trail for its current condition)
• Black trail/camp is "historic", i.e. no longer used
• Orange trail is a non-USFS "use trail"  (trail condition unknown)
• Tan campground has nearby public vehicular access (possibly 4-wheel-drive only)
• Water information may not be valid during drought year (duh!)

General 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.

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!)  

GoogleMaps-specific Usage Notes:
• Sidebar can be removed/added by clicking «/» at sidebar top-right
• Backgrounds "Satellite" and "Map" also available (under "More" button)
• "Terrain"/"Topo" backgrounds can only zoom in to a 1000/500 ft scale vice the 50 ft scales of "Satellite" and "Map"
• Green GM National Forest area does not depict in-holdings within the National Forest
• Mouse left double-click on map centers and zooms in on that location
• For lat/lon info: in "My Maps" (Google Account required) click "New", enable "Lat/Lng Marker", and "Save changes" - then right-mouse-click on map gives option to place marker with location's lat/lon
• You can direct Google Maps to many geographical features by typing a name such as "Cabezo Prieto" into the search entry box at top center.  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 GM) will direct GM to that location. 
• Trail metrics data can be cut off by or extend beyond the "bubble" which pops up when a trail is left-clicked - this is a Google Maps problem

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. 

GPS Notes:
• Free, high-resolution (quadrangle-quality) contour line maps covering California can be loaded onto a Garmin GPS by using the download and instructions at California Topo Map webpage.  [NB: A note on that download page recommends using a newer map, but I do NOT recommend that for the Big Sur area.  The plethora of additional information the newer map includes is seldom useful and clutters up the small screen, making the contour lines harder to read.  It also displays intermittent streams more boldly than perennial streams!  And finally, it highlights its often incorrect "trail" lines, which are often misleading and more harmful than helpful.  Trails in the older file use the same data so can also be misleading, but they are thin dashed lines which are easier to ignore.].  But note that its "trails" (thin dashed lines) are often inaccurate and best ignored.  For hiking in Big Sur, use the Garmin-format Big Sur Ventana/SilverPeak Trailmap since it has accurate trail and camp locations in addition to contour line data. 
• USGS NED 1/3-arcsec elevations have been added to all gpx files
