My Position has Evolved over Time

Today I went mountain biking with friends. I have decided to start documenting the routes we take. I bought a Garmin Etrex Vista Cx GPS unit along with a handlebar mount. It worked extremely well. Here is our route. The altitude data are flawed for the first .2 miles, but after that the GPS got dialed in. Check it out:



You can zoom to see things more clearly, or click on the altitude profile to see our altitude changes (the Y-axis on this graph is in meters). You can see that we did two ascents to the water tower. The drop at about mile 4.2 is where my buddy Dave went over the handlebars. The "Snow Cave" is at about mile 4.7.
