Question

if using a compass in the rocky mountians your magnetic declination will be

west of true north, east of true north or unaffected

Answer 1

Magnetic declination is the angle between the direction to the earth's rotational axis and the magnetic north pole. In other words, declination is the difference between true north (astronomic or axial, almost the same) and magnetic north (the direction the compass points). In North America (except in the extreme north), both of these points are in the same direction (or a zero declination) in an approximate north-south line running just west of the Great Lakes roughly following the Mississippi River. Because the earth's north rotational axis is north of the magnetic north pole (by "true" direction), all points lying west of that line have an "east" or "positive" declination, and points to the east have a "west" or "negative" declination.

The declination in the Rocky Mountains is east of true north. It would vary from about 15°E in the southern Rocky Mountains in Colorado to about 35°E in Yukon. You would have to know what part of the Rockies you are in to give a better answer.

Answer 2

It might rely on the place you might be in the rockys. In case you are in the south it could be appox 15 deg east of proper north and as you go toward washington state it could go to appox 21 degrees east of real north. Ps mike, no offence intended, but magnetic north differs from proper north as a result of 'magnetic deviation' So sure authentic north is continuously genuine north but magnetic north is not

Answer 3

The sky appears blue because blue light is shorter-wavelength, and when light from the sun reaches the upper atmosphere, the short-wavelength light is absorbed and re-emitted by gas molecules in the upper atmosphere, while the longer-wavelength light (red light, for example) passes straight through the atmospheric gases and reaches the earth's surface. The blue light basically bounces around in the atmosphere a lot, so the sky appears blue. Basically, ozone gas, a major constituent of the atmosphere is blue, and therefore the atmosphere is blue.
