[BorregoWrangler]

"A little more than twenty miles southeast of San Diego, within the boundaries of the Mexican land grant Rancho Jamul, a curious and substantial masonry structure stands isolated at the foot of a low hill. The structure houses two octagonal kilns, a brick smokestack rising more than thirty feet above them. Limestone and clay from a deposit on the hill behind were once burned in these kilns by the Jamul Portland Cement Manufacturing Company, an enterprise created during the boom of the 1880s." -San Diego Historical Society
