Hi GG,

Best way to map the trail is to use a GPS that doesn't have such restrictive limitations on breadcrumbing. Given that this is not an option, you seem to have hit on the next best solution on your own - manually setting a waypoint at each trail feature or change of direction. You can still use the track feature, but don't rely on it.

Trail features should use different waypoint icons or descriptions (branch, scree, water crossing, spring, etc.). Altitude is a nice thing to know (don't know if the Etrex records this) but remember that GPS altitudes can be off by several hundred feet.
