Which north arrow on a USGS topographic map points toward the North Pole?

On a USGS topographic map, the north arrow that points toward the North Pole is true north. True north refers to the direction along the earth’s surface that leads to the geographic North Pole, making it essential for accurate navigation and orientation. In the context of maps, true north is typically depicted by an arrow or a line pointing directly towards the North Pole, which helps users align their maps with the earth's magnetic and geographical features.

Other types of north, such as magnetic north and grid north, serve different functions in navigation. Magnetic north is based on the Earth's magnetic field and can vary over time due to changes in the Earth's magnetic core. Grid north is aligned with a map's grid system, and while it approximates true north, it can also deviate depending on the map projection used. Field north is not a standard term used in mapping and may refer to magnetic north in specific contexts, but it is not relevant in relation to USGS topographic maps for identifying the direction of the North Pole.
