Hundreds of petroglyphs can be seen on the volcanic basalt outcrops that lie next to the Gila River. The area is believed to have been utilized for thousands of years, more so from A.D. 500 until the 1800s. Many archaeological remains left by prehistoric peoples are visible, but the most predominant are the petroglyphs. Petroglyphs are difficult to date, so archaeologists have no way of knowing their age. Other features at the site include sleeping circles, geoglyphs, trails, rock alignments, and a historic canal. Due to its proximity to the Gila River, the area has a long history of use as a major traveling route by Spanish explorers (Juan Bautista De Anza National Historic Trail alignment), missionaries, and people heading for California (including the Butterfield Overland Mail route). In addition to cultural resources, the area contains a sizeable mesquite bosque with significant wildlife habitat. The site is monitored regularly by volunteer Site Stewards.
