Tye,

Here is how I would do it.

I'm in the St. Charles USGS map. Let me know when you have it.

I'm on Grid 31, let me know whan you see it.

I'm on the trail on an azimuth of 150 at .5 miles from x8407 (a small peak.)

Azimuth is always a direction from.

Then when the helicopter comes, point your compass at them and read the back of the dial.

I'm directly ahead at a bearing of 240. (This tells them the heading to fly.) When they are pointed right out you, have them turn right a few degrees so the copilot can see you out the left side.
