GPS readings are dependent upon orbiting satellites for accurate
coordinates. Each day has a schedule of the hours with dependable coverage by
the available satelites. Wide variability in readings can occur during cusp
periods of satellite coverage. Additionally, forest canopy cover can skew
readings.

Most of the work I had done seemed within the ballpark, but several

locations were way off, especially trying to find the first windmill N
of

Rich Cabins. When the GPS told us we were there, we were still
in the

middle of forest and not a clearing in site. We did some
guestimation with

the map compass (kind of hard to triangulate in the middle of a
forest!)

  found our way - about 15 more minutes to find the windmill.

  Signe,

 

  Did you find them way off too? I know I entered several
camps from a list

  obtained from Sheldon's site that appeared to be much closer to
"reality".

    Since demonstrating ability to use a GPS is one of the Venturing
Ranger

    Award requirements, when I hiked with a crew of Venturers in
2001, we

took

    advantage of the opportunity to use the GPS at Philmont. As
others have

    observed, proper use of a GPS requires being aware of several
factors,

    including the fact that it does not *exactly* pinpoint
locations. There

    will always be some deviation and users must of course keep this
in

mind.

    It is also my strong opinion, and probably the opinion of just
about

every

    other GPS user out there, that one can not make it a substitute
for map

 

    compass skills.

   

    I entered waypoints before hitting the trail, and then I also
marked

    waypoints in my GPS as we went along the trek. The
waypoints taken from

  the

    locations themselves are in a spreadsheet that Selden has put on
his web

    site. http://w4.lns.cornell.edu/~seb/philmont-t19-gps.xls

    The waypoints are limited to the trek we did last summer, and
since it

was

    all North Valle Vidal, it will have limited use for any
treks this

  summer,

    but you should know those are from-the-trail markings and not
based off

  the

    map grids. Also, Trek 19 that we did in '01 is a
different itinerary

than

    the '02 Trek 19. The deviations of what my GPS
recorded where yours

  will

    take you will still be there, but they should be much closer than
the

map

    readings.
