Calling all you GPS gurus out there! ;-)
Took the ol' GPS out for a first spin on Monday on my hike up to Wind Cave in Logan Canyon (Garmin eTrex Vista Cx, just FYI). Wanted to keep track of how far up I'd hiked, so I reset the Trip Odometer at the bottom of the trail & started off.
All the way up the trail it was doing a great job of keeping track of where I was, how far I'd hiked, etc. (Although the recorded distance to the cave didn't quite match what the trail marker said -- was supposed to be 1.3 mi. to the cave, but I was just a shade over 1.5 mi. when I got there.)
However, while I was getting ready to head back down after digging the camera out of my pack & taking in the great views up there, I looked down at the Trip Odometer only to be shocked that it thought I'd hiked close to another 7 miles in those few minutes... and even while I was standing still, it was clicking off a couple tenths of a mile!
Now, either Wind Cave is also a rift in the fabric of space-time, or something monumentally screwy happened to my GPS signal (or even possibly -- and likely being a noob -- user error).
Anybody ever seen anything like this before, have any idea what went wrong?
Thanks!
