Gulick, Howard E. “The Baja California Mission Trail – Loreto to El Rosario.”
*Unpublished paper made available by the author. Encompasses intelligent and informed suppositions about the route of El Camino Real. Although it is supplanted by first-hand field research, it remains a model preliminary study, marshalling all manner of indirect evidence of the trail. *From Harry Crosby, who consulted with Howard Gulick in the preparation of his 1974 book, The King’s Highway in Baja California.
