Glatiation and glacial movement during an ice age was not(is not) a constant continuous thing. Once enough ice and snow had built up to get the glacier moving the ice would move in one direction for awhile. Then it might stall or stop moving for a number of years and then start up again moving this time in a different direction. The farther you get away from the source usually the more variable the direction. If you look at the snap lake map you will see two main ice directions shown. So imagine that you put a circular mark on a piece of paper, this represents a diamond pipe and you have used ink or an oil paint. Now imagine laying a piece of plastic drafting milar over this. You slowly move the sheet in one direction for a bit, stop and then move it in another direction. (You can move it in as many ice directions as you want.) What do you end up with? A line which zig zags back to the source. (Those zigs and zags would be displaced indicator trails.....but they still lead back to the source. What I have just discribed is an over simplified version of what really happens. To do it accurately you also have to factor in that as material moves out from the source it also fans out so to do it right you have to draw a fan around each of those center lines and that when the next ice direction occures it again fans and smears. Which is why when you get a good distance away from a source you can get quite a wide belt of thinly dispersed indicator minerals. Boulders of kimberlite particular a train of numerous boulders wouldnt move far however before they turned into rubble because the boulders are soft so you should be able to follow them back to the source which should be firly close. There are also alot of local variables to throw into this mix but that is the general gist of it. So if you were following the trains of indicator minerals back over long distances you could have several of the zigs and zags I mentioned but the trains should also be getting stronger and narrower and when you start finding actual boulders, I would assume you are getting quite close to the source. Hope that helps, whom ever you are:)
