Cape Columbia marks the most northerly point of land in Canada. It is also one of the northernmost points on Earth. Interestingly, the north geomagnetic pole is located on the island. This is the south pole of the Earth's magnetic field.

The island's physical structure is defined by complex geology. It contains three major geological regions. The Grant Land Highlands consist of a large belt of fold mountains. These dominate the northern face of the island. This area is part of the Franklinian mobile belt. This zone contains volcanic and intrusive rock from the Cretaceous period. South of these highlands lies the Greely-Hazen Plateau. This is a large tableland made of sedimentary and volcanic rocks.

A coastal sedimentary plateau covers most of the island. This area features highly eroded sedimentary peaks. It is part of the Franklinian Shield. In the southeastern corner, the island includes an extension of the Canadian Shield. This part consists of Precambrian igneous and metamorphic rocks. Additionally, there are syntectonic clastics known as the Ellesmere Island Volcanics. These belong to the Sverdrup Basin Magmatic Province. The island's features were established by uplift and faulting before the Pleistocene epoch. Later, isostatic rebound caused more uplift after the Last Glacial Period. Glacial ice, meltwater, and sea ice scouring shaped the final landscape.

Archaeological records on the island are remarkably complete. This is because artifacts deteriorate very slowly in this climate. Cold, dry winds naturally freeze-dry items exposed to the air. Items buried in the permafrost are also well preserved. Permafrost is ground that remains frozen for long periods. Because of this, ancient settlements look almost exactly as they did when abandoned.

Earlier inhabitants included the Arctic Small Tool tradition peoples, or Paleo-Eskimos. They lived in small hunting bands. They mainly hunted muskoxen in the interior. Six different small-tool cultures have been identified in the Smith Sound region. These include the Independence I, Saqqaq, and Dorset cultures.

The Thule culture arrived around 1000 CE during a warming trend.

They occupied the Smith Sound area near polynyas. A polynya is an area of open water surrounded by ice. The Thule had several technological advantages over previous groups. They used effective weapons, kayaks, and umiaks for marine hunting. They also used sled dogs for transport. The Thule completely replaced the Dorset culture after 1300 CE. They maintained extensive trade networks. They even traded meteoritic iron from Greenland.

Some Norse artifacts, like chain mail, were also found in Thule sites. These date from roughly 1250 to 1400 CE.

European exploration began with a search for the Northwest Passage. William Baffin first recorded the island in 1616. However, the Little Ice Age slowed exploration for two centuries. In 1818, John Ross led the first recorded European expedition to Cape York. Later, the search for the lost Franklin expedition drove intense interest. Edward Augustus Inglefield named the island in 1852. He named it after Francis Egerton, the 1st Earl of Ellesmere. Other expeditions, like the Second Grinnell expedition, charted the Kane Basin.

Canada established sovereignty over the region in the early 1900s. The North-West Mounted Police conducted patrols to solidify this presence. In 2021, the population was only 144 people. These residents live in three settlements: Alert, Eureka, and Grise Fiord.

The island is part of the Qikiqtaaluk Region in Nunavut. Today, more than one-fifth of the island is protected. This area is known as Quttinirpaaq National Park.
