Lansing Post is located at the confluence of the Stewart and Lansing rivers within the Traditional Territory of the First Nation of Na-Cho Nyäk Dun. The Northern Tutchone and upper Stewart River people used the site as an annual meeting site in the early 20th century. The trading post was established by Frank Braine and Percival Nash in 1902. It functioned both as a fur trading post and trading centre for the Northern Tutchone, Peel, Macmillan River and Tulita (formerly known as Fort Norman) people. Trade began to decline after the Fort Norman families returned to the Northwest Territories, and the Mervyn family, who had taken over the post by 1912, moved into Mayo around 1938. The site was abandoned in 1950 when the road to Mayo was constructed.

Schedule A - Chapter 13 of the Na-Cho Nyäk Dun Final Agreement states that the Lansing Heritage Site shall be established as a Designated Heritage Site and that the Government of Yukon and the First Nation of Na-Cho Nyäk Dun shall jointly prepare a management plan for the site.

The management planning is complete and the Lansing Heritage Site Management Plan was signed on February 14, 2018 in Mayo, Yukon.
