To solve this cache you will need a map and a protractor or a mapping program such as OziExplorer. Why not bring the bike and enjoy the trip?
Shell and I have been in the NSW RFS for the last 10 years. I wanted to share some of the navigational lessons that we have learnt. Believe it or not but GPS has not totally replaced the trusty compass and a map for all of us. In the fire service we still use both for fire spotting. How fitting that a cache of this type is located here in one of the most fire ravaged parts of town during the 2003 firestorm.
For the purposes of fire spotting triangulation is very helpful as often you can get the bearing of smoke but often it is very difficult to get the distance, therefore if your were to only take a single bearing it is very difficult to locate a fire. By taking three bearings you can use triangulation to accurately determine the location of the fire. You will see just how accurate when you find this cache.
Based on these principles use the following to calculate the cache location.
Assume that on a perfectly still day I placed a flare next to the cache. Our fire spotters are located at the following caches have reported a smoke sighting at the following bearings.
Spotter 1 is at GC1BMK4, she can see smoke at a bearing of 158.5 Degrees Magnetic.
Spotter 2 is at GCD0F7, he can see smoke at a bearing of 120.4 Degrees Magnetic.
Spotter 3 is at GC19KTA, she can see smoke at a bearing of 291.9 Degrees True.
With this information you should be able to find the cache location as the flare soon burns out.
While your at the GZ keep an eye out for crazy muggles. You'll understand when you get there and look down the hill!
