Probably the simplest and most accurate way is to use position 
measurements to determine the direction.  Look in what direction the 
feature you want to orient points, identify a point in that direction 
at suitable distance, go to that point and record the position (or use 
the already mapped data of it) and use both positions to determine the 
direction.

With very simple tools (like piece of cardboard with an angular scale 
drawn on it) you can also record relative orientations and this way 
avoid the need to find a reference point in exactly the direction your 
object points to.  This is how you used to measure everything before 
the age of GPS.
