Rode here a couple times this week.  Almost 8 miles of technical riding.  Click the pic for the interactive Google map.

Here is the profile of that trail (careful! - its huge so you can see the most detail).  The way we rode this trail it goes in a figure 8, starting at the bottom right and going across to the bottom left, then to the upper right, across to the upper left, then down to the bottom right.

Here is a Google Earth version, with altitude data included so you see a wall indicating the trail altitude.  Clearly not great accuracy, but probably somewhat close.
