The site as a whole is quite complex, consisting of multiple historic and cultural features which include Native American ruins, an 18th century catholic church, the western most battle field of the Civil War, and a historic ranch, the Forked Lightning, which was once the home of the movie star Greer Garson. Two sites within the park, the pueblo and the Glorieta Pass Battlefield, are National Historic Landmarks.
Originally designated a New Mexico state monument in 1965, it was established as Pecos National Monument by President Lyndon Johnson in 1965. 25 years later the park was greatly enlarged and renamed to Pecos National Historical Park.
The main unit of the park preserves the ruins of Pecos Pueblo, also known historically as Cicuye. The first Pecos pueblo was one of two dozen rock-and-mud villages built in the valley around AD 1100 in the prehistoric Pueblo II Era. Within 350 years the Pueblo IV Era Pecos village had grown to house more than 2,000 people in its five-storied complex. The main unit also protects the remains of Mission Nuestra Señora de los Ángeles de Porciúncula de los Pecos, a Spanish mission near the pueblo built in the early 17th century. A 1.25-mile (2 km) self-guiding trail begins at the nearby visitor center and winds through the ruins of Pecos Pueblo and the mission church.
Forked Lightning
The Forked Lightning was added to Pecos after actress Greer Garson sold the property to the Conservation Fund, in 1991, which then donated the land to the National Park Service, increasing the area of the park by 5,500 acres..
While the cultural history of the site is diverse and complex, so is that of the site’s conservation. The largest feature, the mission, was constructed of adobe, a material which was used extensively in the arid climate of the American Southwest, but which has fallen into disfavor for a variety of reasons which include building code, lack of skilled labor, and cost of construction. In order to protect the historic adobe, in some cases Pecos has followed the same approach which Fort Union has employed, applying a thin layer of modified mud over the top of the bricks to “shelter” them from the elements. In addition to using shelter coats, the park has also employed a second approach to protection, using veneers. New exterior walls are constructed from new adobe blocks. These veneers, shelter the delicate original material by encasing it in new, sacrificial adobe walls. Both approaches offer protection, however each method has drawbacks.

Conservation History
The records which detail the excavation, stabilization, and maintenance of resources at Pecos PNP span more than a century. The development of the site, as it continued to be excavated and stabilized for interpretation, is detailed in The Spanish Colonial Architecture of Pecos, (Ivey 2005). However, the types of documentation methods used by cultural resource managers and archaeologists has never been formally reviewed or assessed. 
Since the beginning of excavation and stabilization work at Pecos by Jesse Nusbaum and Alfred Kidder in the early20h century, many  archaeological projects and stabilization efforts have occurred on the resources at Pecos. In several instances, documentation of these efforts is confined to narrative notes and archaeological drawings (plan, profile, etc.) These tend to be either incomplete or unclear. Bill Witkind, who was the director of excavation activities between 1939 and 1940, famously created a very complex numbering system, which made him prone to referencing incorrect room identifiers in his notes. Later, the excavation work performed under Jean Pinkley from 1966 to 1969, was found to be substantially lacking in documentation at the time of her untimely death. Notes and field note books, while easy to complete in the field at the time activities are being conducted, tend to be disorganized, lacking in completion, and not easy to reference. Thankfully, James Ivey mined these archaeological notes for critical information, which were then organized into a narrative in The Spanish Colonial Architecture of Pecos; Courtney White also included these in Convento Room Histories (date).
Making sense of original fabric, and what interventions were made when and where and by whom, has been of interest to park staff since the mid-1970s. Over the course of twenty years, several park archaeologists and outside consultants put significant effort into organizing the archaeological and maintenance records for prehistoric and historic structures. The most useful of these are: the stabilization history of the entire site, A Stabilization History of Pecos National Monument: 1974 and Before, by Larry Nordby, Gary Matlock, and William Cruetz in 1974; several reports written by James Ivey in the 1980s focusing on the evolution of  the Spanish colonial architecture of the site, leading up to his magnum opus A History of the Establishment of Pecos National Monument and The Spanish Colonial Architecture of Pecos Pueblo, New Mexico in 2005; and Convento Room Histories, a compendium of references to stabilization by rooms in the Convento written by Courtney White in 1994 which builds upon the efforts of Nordby et al. to update the narratives with work completed in the elapsing twenty years. These documents provide an essential guide for cultural resource managers to reference the standing walls and features by location, and access an entire past history containing stabilization and condition records.
Conditions and Stabilization Documentation (1974-present)
In the 1970s, cultural resource documentation shifted away from archaeological records to documentation about the condition of the walls. The first instance is Nordby, Matlock and Cruetz’s report from 1974, which describes in narrative the condition of each wall face or elevation by room, along with the present dimensions of the walls. After this, the only documentation consists of field notes from Nordby. Into the 1980s, documentation is sporadic. A brief document was prepared in 1985 which contains a list of preservation activities and in 1986the only documentation consists of reports for emergency stabilization, including work on the North Transept wall in the 18th C. Church. Some information from this period between 1974 and 1987 was recovered from interviews between maintenance crew members and Courtney White, and their recollections are included in Convento Room Histories.
CAC Contributions
The products of this project phase, including the Conservation History Database, represent yet another moment in which knowledge is consolidated. Descriptions of the work carried out since the mid-1990s will serve as an “update” to the room chronologies. Departing from the conventions used in the past, however, is the addition of photography to aid in illustrating conditions and interventions. The increasing reliance on photography as a tool for recording, encouraged by the introduction of digital methods, means that the amount of information to be potentially gleaned from picture records is substantially greater than written forms or descriptions. By making photographic metadata queriable, the Conservation History Database is thus a more potent and sustainable tool for the cultural resource managers at Pecos NHP.
