An important element of Islam is the Qibla - the direction of the sacred stone of the Kaaba, in which devout Muslims should be sent to face during prayer.
In recent years Muslims in North America have differences over the method of determining the Qiblah. If you look at the usual flat map of the world, in the right direction - south-east. However, if you take the globe, the shortest arc to Mecca is to the north-easterly direction. Most of the Muslims, but not all, adheres to the latter.
