![]() ![]() Then measure the perpendicular distance between the lines. To measure trail width, find a relatively straight part of the trail and imagine or draw out two parallel straight lines that just touch the outsides of the alternate sets of tracks. The width of the zig-zag, known among trackers as trail width, varies from one species of animal to another. The trail in the next photo, made by a deer walking from bottom to top, is a good example of a zig-zag made by a four-footed animal. And since the feet on each side fall to their own side of the center line, the overall pattern is a zig-zag. The video doesn’t show the pattern on the ground, but it’s easy to see how the horse leaves a series of double impressions, each one a front track overlaid by a rear track. Notice that as each front foot leaves the ground the rear foot on the same side comes down in the spot just vacated by the front foot. If you click on this link: Bing Videos, then click on horses walking youtube and start the video, you’ll see a horse walking in slow motion. So let’s take a look at a video of a horse. Fortunately for us twenty-first century trackers, there’s a tool that can bridge the gap–the internet. ![]() Watching animals helps, but it’s hard to follow foot placement when animals are moving in real time. Two legged zig-zags are pretty straightforward, but four-footed animals also create zig-zags, and it’s not as easy to understand how a four-footed animal can do that. ![]()
