Returning, however, to the 19th century after General Kearny's passage through Arizona, Americans began to frequent the region in search of gold and silver. The influx of fortune-seekers was also the impetus for the arrival of American troops to protect them. It was near what is now known as Kearny that the first significant military garrison against the Apaches was established in 1859. Originally called "Camp Arivaypa" (located not far from what is now Central Arizona College Aravaipa Campus), it later became Camp Grant (which itself was moved to south of Mt. Graham in 1871). From the time of the establishment of this fort onward, the Americans could no longer be prevented from settling the region. The area became an integral part of what is often called the 'Wild West', with mining and ranching being the magnets that drew early settlers. Apaches, of course, took fierce issue with the intrusion, and their resistance was immediate and bloody. However, late 19th and early 20th century miners and cattlemen were rough, tough survivors and they were determined to stay. Gradually, the Apaches realized they had no recourse, particularly after a horrible massacre of many of their people at Camp Grant in 1871, and they finally consented to the establishment of a reservation on the San Carlos River in 1872.
