In 1831, Enloe entered into a partnership with William Holland Thomas (1805-1893) to form the Oconaluftee Turnpike Company. The company widened the Indian Gap Trail from Oconaluftee to the crest of the Smokies, allowing wagon access to saltpeter mines on Mount Le Conte. The road's first tollkeeper, Robert Collins, would later guide Arnold Guyot on surveying expeditions across the crest of the Smokies. Mount Collins, between Clingmans Dome and Newfound Gap, is named for him.
