It depends on where in the Rockies you are. New Mexico? Colorado? Wyoming? Montana and Idaho? There will also be the standard deviations from the norm based on altitude, solar activity, weather, local anomalies, etc. The deviation will range from about 9o in northern New Mexico (which is the southern end of the range) to about 15o in northern Montana and the Idaho panhandle. Use the link to the NOAA web page where you can get a magnetic declination for any geographic location within the U.S. along with some correction factors. It is even searchable by zip code to make it really easy to approximate things quickly.

What is the name given to the difference between true north and magnetic north?
magnetic variation
If the magnetic North arrow in the declination diagram is to the left or north Gridline then what should the Compass reading be?
If the magnetic North arrow in the declination diagram is to the left of the north gridline, this indicates that magnetic North is west of true North. To obtain a compass reading that aligns with true North, you would need to add the declination angle to your compass reading. Therefore, if the magnetic North is to the left, the compass reading should be adjusted accordingly to the right (east) to compensate for the declination.
What is the name of the difference of true north and magnetic north?
The difference is referred to as magnetic, or compass, declination.
What happens to the angle of declination when you are closer to the poles?
As you move closer to the poles, the angle of declination increases. This is because the Earth's magnetic field lines are more vertical near the poles, causing the magnetic declination— the angle between magnetic north and true north—to become more pronounced. In extreme polar regions, the declination can approach 90 degrees, where magnetic north aligns closely with the vertical orientation of the Earth's magnetic field.
True or false Declination is the difference between true north and magnetic north?
True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).
What is the purpose of a declination?
Assuming the subject is magnetic declination the difference between the north pole and the true north pole this difference, is the magnetic declination, there is not information on what purpose it serves.
How are you affected by magnetic declination?
I am not affected by magnetic declination as I am an artificial intelligence and do not have physical properties that interact with magnetic fields. Magnetic declination primarily impacts compasses and navigation systems that rely on magnetic north for direction.
What is the angular difference between true North and magnetic North is called?
There is a general geographical difference, called magnetic declination. In addition, there may be differences that arise locally, as a result of nearby objects that attract a magnet, which is called magnetic deviation. Related links are given below.
In what part of North America is the magnetic declination greatest?
The magnetic declination is greatest in the northern part of North America, particularly in areas close to the magnetic North Pole. This includes regions of northern Canada and Alaska, where the declination can exceed 20 degrees. As one moves southward, the declination generally decreases.
What is the name given to the difference between true north and magnetic north?
magnetic variation
What is a magnet declination?
Magnet declination is the angle between magnetic north and true north. Declination is considered positive east of truth north and negative when west.
If the magnetic North arrow in the declination diagram is to the left or north Gridline then what should the Compass reading be?
If the magnetic North arrow in the declination diagram is to the left of the north gridline, this indicates that magnetic North is west of true North. To obtain a compass reading that aligns with true North, you would need to add the declination angle to your compass reading. Therefore, if the magnetic North is to the left, the compass reading should be adjusted accordingly to the right (east) to compensate for the declination.
What is the name of the difference of true north and magnetic north?
The difference is referred to as magnetic, or compass, declination.
What is the term used for difference between true north and magnetic north?
Magnetic declination or variation.
What is the magnetic declination in Jasper al?
The magnetic declination in Jasper, Alberta, Canada is approximately 18 degrees east. This means that magnetic north is 18 degrees east of true north in this location.
What is the Declination between true and magnetic north for San Angelo Texas?
As of my last update, the declination between true north and magnetic north in San Angelo, Texas, is approximately 4 to 5 degrees east. However, magnetic declination changes over time due to shifts in the Earth's magnetic field. For the most accurate and current information, it's advisable to consult a magnetic declination map or an online calculator.
What is the magnetic declination of Spokane Valley?
The magnetic declination of Spokane Valley is approximately 16 degrees east. This means that magnetic north is about 16 degrees east of true north in that location.
