We went back to Henry Coe State Park this weekend. This time I didn’t forget the camera, so you can see the pictures. I also brought my foretrex 101 which, when combined with a data cable, allows you to see where we went (click for a bigger version):

I saved waypoints where we camped – Kelly Lake and Willson Camp. The car was parked at the Coe Hunting Hollow entrance.
Here’s the GPX file for you tech heads who want to drag and drop it into Google earth for yourself (Note:You need to expand the time slider to see all the tracks and version 4.1.7087.5048 or later). Cynthia wanted to see our net altitude changes, so I did an Excel import and created a profile graph – as you can see, the first day was brutal.
Some other highlights:
- I caught my first fish on my own fly rod – a big (honest!) bluegill in Kelley Lake on a poorly cast wet fly
- Wild Boar repeatedly came to visit us in the middle of the night at Willson Camp on Saturday night and scared the crap out of Cynthia. They don’t run away when you yell at them
- I didn’t get bit by ticks like last time
- We saw 8 other people over 3 days
All in all, it was a great trip. We scratched that long overdue itch to be in the back country, and it was cool to see a new area of the park.

Nice work on the altitude profile. That explains the photo of Cynthia past out in the tent. I couldn’t see the boar at all in the picture, so i did a color inversion and I see that they weren’t boars at all… they were little blue eyed gnome ghosts.
Also I could load the GPX but it didn’t seem to add any place marks of tracks for me to look at. Do I need the purchased version of Goog earth?

Yeah, the boar picture is really poor, you need to view the hi-res version full screen to see the faintest outline. Also, you helped me discover you need to have a very recent version of Google Earth for the .gpx to work right, and even then it\’s a bit dodgy. You need to turn on the time slider, and then expand it to show the whole period if you want to see all three days at once.

ZOMG! That map is super cool! I’m wondering if I can do the same with my ForeTrex 201. I may be installing google earth as soon as I get home. Sweeeet.
Looks like a fun trip! Great to see pix of that place, maybe Suzy and I can go next time.

I installed Google Earth on my Linux box today, but unfortunately it’s an older version so the GPX functionality hasn’t yet introduced. Fortunately, however, there is an alternative. Google Earth also accepts a KML (KeyHole Markup Language) format which is easily created with GPS Babel. Just type the following.
gpsbabel -i gpx -f in.gpx -o kml -F out.kml
GPSBabel was also able to grab my GPX file directly from my Garmin with this command line:
gpsbabel -t -w -i garmin -f /dev/ttyUSB0 -o gpx -F out.gpx
(For windows users that have USB cables try :usb instead of /dev/ttyUSB0. If you have a serial cable, try COMx where x=the COM port you’ve connected your GPS device to.)

[...] All my thanks go to Pat for showing me how to get the data off of my Garmin ForeTrex 201 and insert it into Google Earth. It produced beautiful products like this and this of both the Deschutes day hike in Oregon and the Cathedral Lake backpacking trip in Yosemite. I’m going to use this on all my future trips. [...]
