 The Island Creek Coal Company , the North East Lumber Company , and the Cole and Crane Real Estate Trust leased to the commission 1 @.@ 5 acres ( 0 @.@ 61 ha ) encompassing the tree for it to be managed as a state park for the lifetime of the tree . The commission removed vegetation from the immediate land around the tree , constructed a fence around the plot , and built a bridge crossing the Trace Fork of Pigeon Creek so that motorists could access the park from the highway . The state built cooking ovens , picnic tables , and benches along the tree 's southern slopes . Also , due to its enormous size and advanced age , the Mingo Oak acquired spiritual and inspirational significance . It became a place of worship , and a pulpit and benches were built beneath its branches . During the summer months , outdoor sermons were delivered by preachers at the tree . The Mingo Oak was also credited with raising awareness of conservation .
