Anybody know the compass declination for Yosemite?

pretty sure it is 15 degrees
unless sighting distant peaks I find it a non-issue since there
are so many trails along with valleys
kinda hard to get lost IMO

It's about 14 degrees according to http://www.magnetic-declination.com/

YOSEMITE VILLAGE CA
Latitude: 37° 44' 43" N
Longitude: 119° 35' 50" W
Magnetic declination: 13° 57' EAST
Declination is POSITIVE

It's moved over the years. Back in the late 60's using maps from the 40's and 50's the declination was 16 1/2 degrees.

Why is the declination even important?

by **balzaccom** » Thu Jun 11, 2009 9:07 pm

Because most maps give true north...and if you look at your compass, it won't correspond to North on the map.

Good way to get lost.

I'll take a map and compass over GPS any day! My compass never needs batteries.
