Navigation Navigation on the trail is an easy-to-learn skill, with several tools readily available. Like any other skill, it is enhanced by regular practice. A common method of learning a particular trail or area is by following a friend or acquaintance who knows the territory. This usually requires some repetition. The key is noting landmarks that are not likely to change. Trail maps are an important tool. Most of the Tug Hill region, much of the Adirondacks, some state parks including Allegany and Letchworth, and numerous DEC land management areas have snowmobile trail maps. Many clubs and county club federations publish maps that cover other areas of upstate New York. Snowmobile trail maps can vary considerably in quality and content. Sometimes changes are made after the map is printed, so always check with local sources for the latest information. A compass is another important navigation tool. Snowmobilers should know how to use a compass and always carry one. Inexpensive compasses are often included in trail and survival kits. Compasses are available at sporting goods stores and through hunting and hiking catalogs. A GPS receiver can be used instead of, but ideally in addition to a map. They can be used to record waypoints so you can trace your way back to your starting point and can be loaded to display trail data for the area you will be riding in. There are some inherent terrain and accuracy limitations with recreational units, but they are reasonably priced and can make long distance riding much easier. See local sporting goods stores and hunting catalogs for more information. Trail Markers and Signs Trail markers and signs are designed to communicate information about the trail to the rider. In order to establish a degree of uniformity throughout North America, the International Association of Snowmobile Administrators (IASA) has established some basic sign standards for all snow belt states and provinces. Here are the common signs seen on New York snowmobile trails. 25
