I have a 1965 raised relief map of California I use to estimate fireball 
explosion positions. It is a Nystrom "Lambert Conformal Conic Projection" 1: 
1,000,000.

My question is how close are the Longitude lines in (alignment) to TRUE 
NORTH ?

Latitude or elevation is not an issue. Thank you.

(I have had varying answers from Nystrom, who suggested aligning the map(?) 
with a compass, then rotate the map CCW 16 degrees ). There are no magnetic 
declination reference marks on this map. Just latitude and longitude.
