What is the most northern point of land in the world?

According to the American Geographical Society, the most northern point
of land in the world is Cape Morris K. Jessup on the extreme northeast
area of Greenland.

Commander Robert E. Peary, an arctic explorer, killed a musk-ox within a
half-mile of this point, and is credited for naming it, also. The cape
was named after a New York banker and philanthropist, Morris K. Jessup.
Jessup helped finance several of Peary's expeditions.
