Navigation
You must carry both a GPS device AND a map with a compass and know how to navigate reliably with both
Winter conditions significantly alter the landscape and can erase trail markings; eg. the distinctive cairns from the summer ACT are covered in snow during the winter. Furthermore, the winter ACT route does not follow the exact path of the summer hiking trail. Frozen lakes and rivers allow for several shortcuts, and the route avoids the highest elevations. Therefore, it’s important not to rely solely on the GPX tracks available for the ACT (though they are still a valuable reference). Instead, follow the dogsled and snowmobile “highway” made by experienced locals who are familiar with the terrain and current snow and ice conditions. This is your main physical navigation aid during winter!
Keep in mind that the exact route can change from year to year and may even be rerouted mid-season. While the GPX track can serve as a guide, if the current tracks in the snow take a different direction, follow them! However, be cautious of smaller side trails made by locals heading to other parts of the backcountry. Always keep an eye on your GPS device or map!
The main navigational challenge occurs during and after a snowstorm or period of intense winds. These weather events can quickly reduce visibility and erase the tracks completely—at least until the first local comes through on their way between Sisimiut and Kangerlussuaq. In such situations, it’s advisable to wait until the weather clears and then use your maps and GPS to navigate.
While reliance on GPS devices, maps, and compasses is vital, adventurers must also be prepared for potential device failures or poor visibility. It’s essential to factor in these navigation challenges when calculating the expected distance covered each day.
When planning your trip, consider the unpredictable weather and limited daylight hours, especially before mid-March. Start each day early and build enough flexibility into your schedule to allow for waiting out bad weather. Take into account that setting up and taking down a winter camp takes much longer that in summer! Pitching a tent, preparing your sleeping spot, melting snow, … with thick clothes and in cold conditions it is not a quick job!
