Erected in 1917 after the original land purchase, this structure became the first building constructed at the camp and remains the oldest surviving Boy Scout-built and Boy Scout-owned camp building in the nation. Built under the supervision of Toledo Council Executive J. St. Clair Mendenhall, it preserved in its wet plaster the finger-written nicknames of his daughters, “Dutch” and “Irish,” along with his own nickname, “Chief.” Originally called the Headquarters and later known for many years as the Main Cabin, it had its original roof applied by Mendenhall himself and served for decades as the summer camp Trading Post. Severe deterioration nearly led to its demolition in 1990, but Tindeuchen Order of the Arrow Lodge 522 rescued and restored it, with lodge members spending more than a year raising funds and providing all the renovation labor; they also founded the Miakonda Scouting Museum within the building in 1991. The structure features a distinctive indoor and outdoor fireplace, and the outdoor ceremonial fireplace is believed to have been connected to the Tribe of Gimogash and the Order of the Mystic Circle, two honor programs that existed in the council during that period. The Toledo Area Council’s Executive Board formally approved a local Order of the Arrow lodge on January 9, 1957, and an organizing committee of selected Explorers and adults from each district met for the first organizational meeting on February 13, 1957, at Council Headquarters under the leadership of Camp Director John M. Claerhout. Invited Explorers were regarded as Honor Campers and included Paul Tait, David Bitter, Bill Steiner, Larry Wright, and others, while participating adults included Francis Drechsler, Paul Koester, and Zearl “Zed” Davis. The first Ordeal induction into the lodge took place at Camp Miakonda on Friday, May 3, 1957, with the ceremony conducted by the Findlay lodge of the Put-Han-Sen Area Council; eleven Wa-Be-Wa-Wa Lodge members were inducted, fifty-three new members joined during the summer of 1957, nine members entered the Brotherhood at the 1958 Conclave at Camp Berry, and David Bitter and Larry Wright became the first Lodge Vigil members in 1960. In 1973, the lodge’s name was changed to Tindeuchen.
