After 1802 , the fort 's buildings fell into disrepair , and by 1806 , they were overgrown with vegetation . According to an entry in the journal of Zebulon Pike during his expedition through southern Louisiana : After the Pike Expedition , few travelers reported the site of the fort . The last report of the fort 's existence derives from an 1874 Missouri travel guidebook relating the physical characteristics of Vernon County . While not explicitly mentioning the fort , the guidebook noted the top of Halley 's Bluff had " the foundations of three furnaces " and " the remains of works — both earth and stone , covering the approaches to the furnaces and the descent to the excavations below , as if thrown up for fortifications . Later , the guidebook suggested that the works were remnants of French explorers who had built a headquarters for their operations there . In the early 20th century , Halley 's Bluff ( and the site of the fort ) became the possession of a Mormon group that eventually separated from the Church of Christ ( Temple Lot ) . This group , known as the Church of Christ at Halley 's Bluff , controlled the property as a compound from 1945 until 1979 . Since a dispute over control of the church in the 1970s , the compound has been the property of the Church of Israel , a Christian Identity group . In the 1980s , the church compound was home to Eric Robert Rudolph , who committed the Centennial Olympic Park bombing in 1996
