Mount Lucania in Yukon is the third-highest mountain in Canada, and the second-highest mountain located entirely within the country. A long ridge connects Mount Lucania with Mount Steele, the fifth-highest in Canada. Lucania was named by the Duke of Abruzzi, as he stood on the summit of Mount Saint Elias on July 31, 1897, having just completed the first ascent. Seeing Lucania in the far distance, beyond Mount Logan, he immediately named it "after the ship on which the expedition had sailed from Liverpool to New York," the RMS Lucania.

Mount Steele is the fifth-highest mountain in Canada and either the tenth- or eleventh-highest peak in North America. Its exact elevation is uncertain. Commonly-quoted figures are 5,073 metres (16,644 ft) and 5,020 metres (16,470 ft). A lower southeast peak of Mt. Steele stands at 4,300 m (14,100 ft).
