Places to Protect

Adamsville Ruins

Coolidge (Pinal County)

Adamsville is a large Classic Hohokam habitation site, dating from AD 1100 to AD 1450, consisting of a platform, mound, at least one compound, a ball court, and 41 associated mounds of which some still have standing architecture. Listed on the National Register of Historic Places, it is located near the 19th century town for which it is named. It’s the second largest Hohokam housing area along the Canal Casa Grande, second only to the combined communities of Grewe and Casa Grande. The current size of the site is 155 acres of which 126 acres are proposed for addition to Casa Grande National Monument. The site is threatened by encroachment from commercial development and the State is not able to provide adequate protection.

Buckhorn Baths

Mesa (Maricopa County)

In 1939 Ted and Alice Sliger established the baths unknowing that their efforts to make a living of the natural mineral waters would help to establish the East Salt River Valley as a mecca for spring training. In 1947, the New York Giants made the Buckhorn Baths their spring training home and continued to do so for over twenty-five years. Willie Mays, Ty Cobb, Gaylord Perry, Leo Durocher and others were regulars at the Baths. The Sligers established a post office, bus stop, water hole, museum, and motel, which they operated for over sixty-five years.

Also known as the Buckhorn Mineral Wells and Wildlife Museum, the latter moniker due to an immense taxidermy collection, the baths have been closed for years. Ted has passed away and Alice is a century old. Listed on the National Register of Historic Places, the location of the Buckhorn Baths makes it a prime target for development, and speculation is rampant.

Arizona State Parks & Trails


Our Arizona State Parks & Trails need your help. The economic downturn and tight state budget led the State Legislature to strip out and redirect most State Park funding. Elimination of the voter-approved Arizona State Parks Heritage Fund in FY2010 caused a $10 million permanent annual revenue reduction and removed the last source of Parks' capital and maintenance funding. This also removed all matching funding for historic preservation projects as well as all local, regional and state park enhancement & trail improvements. We urge the Governor and State Legislature work with the State Parks Board, staff, and advocates to create a full operational State Parks system and return funding through supplemental and sustainable sources. 

Camp Naco

Huachuca City (Cochise County)

This adobe compound was constructed by the U.S. military between 1919 and 1923, as part of the War Department's Mexican Border Defense construction project -- a plan to build a 1,200-mile barrier along the border. After the camp closed, the Civilian Conservation Corps used the complex in the 1930s for staging projects in southeast Arizona. Over the next several decades, the property owners used the structures as rental housing. In 1990, VisionQuest purchased the property for a rehabilitation camp for wayward youth. The rezoning was denied and the camp has remained vacant ever since.

VisionQuest donated the property to the Town of Huachuca City in 2006. By that time, the property had been heavily degraded due to neglect. Many of the adobe structures are eroded from exposure to the elements. The roof of one of the barracks has caved in, and other buildings merely ruins. In May 2006, arson destroyed four of the non-commissioned officer buildings and damaged the roof of a fifth. Presently, unchecked vegetation is threatening the foundation of buildings and increasing the danger of fire.

Broadway Boulevard

Tucson (Pima County)

Broadway was born modern. The boulevard expressed the new American optimism and post-war economic boom. Like many cities, Tucson was growing rapidly. In 1940, the population was 35,000; by 1960 it soared to 212,000. As an important suburban corridor, modern structures were built along its edge to support new neighborhoods with their curved streets and rambling ranch houses. Broadway was a reflection of the American Dream. The Regional Transportation Authority funding, approved by Pima County voters on May 16, 2006, included plans for significant expansion of Tucson's mid-century modern Broadway Boulevard. The scope expands the road from four to eight lanes and threatens 127 significant and National Register eligible properties and the small businesses they house.
