In the late 19th and early 20th centuries, the Jacob Lake area and the rest of the Kaibab was the summer range of the "Bar Z outfit" or the Grand Canyon Cattle company. This brand ran upwards of 100,000 cattle throughout the Arizona Strip. In the early 1900s "Buffalo Jones" used the Bar Z's corrals at Jacob Lake to pen a herd of buffalo which he then drove onto a ranch in House Rock Valley on the East side of the Kaibab. These same corrals were later home to a "cattalo," a hybrid between one of Jones' buffalos and a domesticated Hereford bull. The remnants of this buffalo herd are still in House Rock and occasionally wander up on top of the Kaibab to the Grand Canyon.
