We used the GPS-navigator mainly to keep track of altitude, but as we passed places of interest we saved the waypoints (lat/long) for later use. We never had much use of the waypoints since we didn't have any blizzards on our way down, and we didn't do much of night-trekking, but if you're going there, and you are bringing a GPS-navigator, you might have use of preprogramming your navigator with the following waypoints:

The GPS-navigator usually reported an error of about 30-50 meters, but I think the acutal error was greater. Expect the error to be around 100 meters in both lattitude and longitude if you are going to use the waypoints for night-trekking.
Unfortuantely I didn't get all the way to the top, so I dont have the coordinates (if you find any, or go get them yourself, please let me know).
