About The Maps
These maps are created with GPS data that I logged while
hiking Section A through K of the Pacific Crest Trail in
2007. For most of the sections, a Garmin GPSMap 60Csx was
used for data logging. The GPS was always on while I hiked
and recorded the exact location of the trail.
This data was imported into National Geographic TOPO!
software which was used along with Adobe Acrobat Distiller
to create the printable pdf maps.
These maps are .pdf files and
require only Adobe Acrobat Reader to view or print them.
All maps are in 1:31,680 scale. 1 inch equals 1/2 mile.
They have UTM grids and use WGS84 datum.
Waypoints were edited in Garmin's Mapsource software. Two
types of GPS waypoints are included. The first are
half-mile points calculated using Mapsource's filter
function. These waypoints can be used to accurately measure
distance along the trail. The second are waypoints I
recorded with the GPS while standing near trail landmarks.
The waypoints are shown on the printable maps as blue dots
and also available to load into a GPS if you carry one or
view in Google Earth.
Each half-mile waypoint has a name that starts with the
section letter followed by the number of half-miles it is
from the start of the section. For example in Section C,
C001, C002, C003, C004 etc. Only the even numbered
half-mile points have text labels on the printable maps.
The unlabeled blue dot waypoints on the printed maps are
odd number halfmile waypoints.
Even if you don't carry a GPS these printed halfmile marks
are useful for a hiker as they accurately measure trail
distance. Need to hike 20 miles today? You would need to
hike 40 half-miles. The waypoints are also an easy way to
communicate you location to Google Earth users back home.
Waypoints are also included for almost of the water report
locations listed at www.4jeffrey.net. These waypoints
are named "WR" followed by the approximate trail mile
indicated in the water report. For example WR252,
WR256, WR239. All the WR waypoints were recorded by my
GPS while I was standing at the water source. WR
waypoints are labeled on the maps in larger blue text.
Not all the WR location will always have water, you
should carry a copy of the water report for the latest
information about water on the PCT.
Other water sources I found but not listed in the water
reports, are named WA followed by the approximate trial
mile. They use the same larger blue text labels. Most WA
locations are between Kennedy Meadows and Crabtree Meadow
where the water report does not cover. These are water
locations I found in June of 2007, which was late in the
season of a relatively dry year.
Once in the Sierra, I have stopped marking water locations
as is generally plentiful.
