Dear Friends of EISP,
Our Excavation Season V, which began on October 29, 2011, opened with our presentation to Governor Carman Cardinali of our two-volume report on Excavation Season IV. She noted that the Rapa Nui community, especially high school teachers and students, is very enthusiastic and interested in our work. This field season will continue as we carry out further excavation of statue (moai) RR-001-156 in Quarry Two, Rano Raraku. Reports of all work to date are available to the interested reader in the EISP Archives as Excavation Season I, Season II, and Season III or as Conservation Season I and Conservation Season II.
Before we began our excavation we visited the basalt quarries and outcrops sampled by our colleague Dr. Christian Fischer as part of our XRF analysis project. We have collected XRF data on over 40 sites. That information will be used byRapa Nui student Rafael Rapu in his comparative study of tools (toki) retrieved in our excavations.
Also in May of 2011, Chris Fischer and Monica Bahamondez, director of the Centro Nacional de Conservacion y Restauracion (CNCR), treated the excavated portions of both statues with water repellant. On drizzly days or days with intermittent rain we were amazed to see how well the repellant did its job! Droplets quickly beaded up and didn’t penetrate the surfaces of either statue. We noted that the stone surfaces usually dried within a maximum of ten minutes. We are also now engaged in a plan to share our extensive on-site environmental data with colleagues modeling the island’s ecology.
Our continued excavation of RR-001-156 revealed more about the ritual concerns of those who frequented Rano Raraku interior quarry over about 500 years. We collected further evidence of red pigment (kie’a), an indispensable part of Rapa Nui ritual life and today a valuable part of personal display during performance art.
Interestingly, Rapa Nui oral traditions say that statue carvers were paid for their talent and effort in desirable food, including especially tuna and lobster. At the deepest level of our excavation this season we found tuna vertebrae! Also, we found strong evidence of how the ancient carvers manipulated the statue to raise it upright, pivot it and drop it in a hole 1 m deep cut in bedrock. The process left scars and indents on the statue surface. When seen on statues lying on roads, these same sorts of scars have been interpreted by others as evidence of upright transport methods. Our excavation, however, clearly shows that such damage could have been caused in the quarry. The unpublished notes of the Mana Expedition to Easter Island (1914-15) suggested and support these findings in Quarry 2 and elsewhere in Rano Raraku.
Both of our excavated statues, as you know from our previous letters, are intriguing because they are nearly unique on Easter Island. While many statues have individual petroglyphs, these and only one other statue—of over 1,000 we have documented—have multiple petroglyphs carved as a composition on their backs. Underlying these carvings is a complex symbol found on less than 100 statues. It is referred to by previous researchers as the “ring and girdle” design, and sometimes said to represent the “sun and rainbow.” However, statue RR-001-156 and some others have two “rings” above the crescent “girdle.” We have long interpreted this form as the Rapa Nui version of the Polynesian maro or loincloth (maro is also a unit of measurement). As we noted long ago on a statue torso (007) at Ahu Oroi (12-460), the upright “Y” or “M” element below the maro on both of our excavated statues represents two hafted adzes. This depiction, which may be interpreted as evidence of craft specialization in the form of an emblem, is not consistent, however, and in some cases outside of the quarry it appears to depict other objects. Cristián Arévalo Pakarati, co-director of EISP, has spent hundreds of hours on site over the past months painstakingly measuring and drawing these designs as he supervises the site during our seasonal hiatus from on-going excavations.
We hope you continue to follow our progress over the next few years on this web site. Although we are partially funded by a generous grant from the Archaeological Institute of America, we need your help. Please join Friends of EISP.

Easter Island Statue Project Conservation Initiative Preliminary Report
July-August 2011
Project Target Statues
The target statues from the inception of this project are RR-001-156 and RR-001-157, both of which are located within Quarry 2 of Rano Raraku. RR-001-158 is adjacent to Quarry 2 on the eastward side and was selected by the conservators as a study control. All of these designations are given on EISP Map Sheet 1 (Van Tilburg and Arévalo Pakarati 2009). Rano Raraku, the quarry in which fully 95% of the known 1,042 monolithic sculptural objects documented to date by this project were carved, is a unit of the Corporación Nacional Forestal (CONAF; www.conaf.cl) and, as such, a World Heritage site.

Introduction
The main objectives of this mission, carried out with the assistance of Cristián Arévalo Pakarati, Rafael Paoa Rapu and Vaiheri Tuki Haoa, were firstly, to apply the protective treatment on statues RR-001-157 and RR-001-156 currently being excavated by EISP and secondly, to start the Toki Sourcing Project by analyzing the elemental composition of the ‘toki’ found during the excavation using a portable X-ray fluorescence spectrometer.
Environmental Monitoring and Conservation Mission

March 8-16, 2011
Introduction
The main objective of this mission, carried out with the assistance of Cristián Arévalo Pakarati, was to evaluate the status of the environmental monitoring equipment illegally removed in 2010 and to re-install it on site for a measurement campaign of seven months to November 2011. In addition, another objective was to complete the building of the fence on the site to ensure safety around both equipment and excavated areas and to avoid potential damage from cattle and horses. Finally, a few meetings in relation to the project were also organized with different people on the island.
Easter Island Statue Project Conservation Initiative Preliminary Report
February 2011
This report is the third in a series documenting the implementation of permitted excavations in Rano Raraku quarry on target statues RR-001-156 and RR-001-157 . Specifically, this report deals with the third excavation season, or Phase 3, and is focused specifically on RR-001-156. The conservation follow-up work that is anticipated for March, 2011 will be conducted by Dr. Christian Fischer and documented by him in a separate report.
The target statue for this season is RR-001-156. It was previously excavated by the Mana Expedition to Easter Island in 1914-15 (Routledge 1919). According to Routledge’s unpublished notes, “at the start, the statue was buried to a line midway between the lobe of the ear and the angle of the jaw” (NGS/WKR). Two separate excavations, both of which were haphazard and are poorly documented, were made of the dorsal side of the statue. The first excavation reached “to a depth of 16 feet measuring from the crown of the head.” The second excavation at the back was made “to extend the first excavation to 10 feet from the statue back” simply to take photographs. At the front, excavation reached “to the navel.” Our Historic Level Book provides a synopsis of the excavations and the objects collected.
Easter Island Statue Project Conservation Initiative Preliminary Report October-November 2010
Introduction
This report is a preliminary statement of the tasks undertaken and goals achieved during the second field season of Phase 2 of the Easter Island Statue Project Conservation Initiative. Phase 1 took place in April, 2010 and a full report of that work is on file with the appropriate agencies. This report is a detailed overview but not a final, scientific analysis or synthesis of our findings. That will be produced at the end of the combined work planned for Phase 3 and Phase 4, which entails the similar excavation and study of Moai RR-001-156.
The Conservation Initiative is funded by the Archaeological Institute of America, and its intent is a scientific evaluation of the state of preservation, above and below ground, of the two statues described here (RR-001-156 and RR-001-157). In addition, the Conservation Initiative will monitor and collect scientific data on the discrete environmental contexts of the two statues. These data will be employed to determine the course of stone stabilization treatment to be embarked upon for each statue, and how that treatment may or may not be generalized to other statues.
Easter Island Statue Project Conservation Initiative Preliminary Report March-April, 2010
This project is the first controlled, scientific archaeological excavations ever undertaken in the interior of Rano Raraku Quarry. It is also the first stone conservation and preservation pilot program in Rano Raraku.
All but one of the 22 standing statues (moai) in Rano Raraku Quarry interior have been previously exposed through unscientific and undocumented digging. The Target Statues for this project (RR-001-156 and RR-001-157) have been dug or otherwise disturbed by the Mana Expedition (1914), the Franco-Belgian Expedition (1935), and the Norwegian Archaeological Expedition (1954-55).
The Easter Island Statue Project (EISP) has a 20 year history of archaeological survey on Easter Island (Rapa Nui), the objective of which is the creation of a full and complete, island-wide monolithic and portable statue inventory and the compilation of an historical image record for each statue. Prior to the selection of Quarry Two for the excavations described here, the EISP team completed a five year mapping foray in the interior of Rano Raraku, the volcanic quarry from which 95 percent of the extant monolithic sculpture were produced (Van Tilburg 1994; Van Tilburg, Arévalo Pakarati and Alice Hom 2008).

Field Work
In June, 2009, Christian Fischer, Research Associate of the Cotsen Institute of Archaeology, UCLA and Mónica Bahamondez P., Centro Nacional de Conservación y Restauración joined Jo Anne Van Tilburg and Cristián Arévalo Pakarati (of EISP) in the field on Rapa Nui. Our immediate goal was a fact-finding and reconnaissance field study that would acquaint our colleagues on the AIA Project with the island sites and objects that are target concerns of our upcoming conservation work.

In the interior of Rano Raraku quarry, EISP has mapped and documented every statue in each of their various carving phases, as well as the independent histories of the individual quarries. Two statues, famously dubbed “Papa” and “Mama” by Katherine Pease Routledge, co-leader of the Mana Expedition to Easter Island, 1919, were the immediate focus of our attention. We studied specific issues of stone faulting and breakage, and planned a strategy for environmental monitoring, which will be carried out during 2009-2010. [Read More...]
September 2007
To date, Van Tilburg and the Easter Island Statue Project (EISP) have inventoried 887 monolithic statues (moai) and compiled a metric database buttressed by 24,000 original and archived images. Some 35% of the known statues are located on or in direct relation to ceremonial sites called image ahu (Martinsson – Wallin 1994: Appendix 1 gives 164 image ahu; Van Tilburg 1986; Van Tilburg and Vargas C. 1998).
Rano Raraku, a volcanic crater on the island’s eastern plain, was the source of the sideromelane (basaltic) tuff from which 95% of the statues were carved. This source is irrefutable as there are 397 in situ statues, of which 141 in various stages of completion have recently been mapped by EISP in the interior quarries (Van Tilburg 2005; www.eisp.org). Much rarer statue lithologies are basalt (hawaiite lavas) from three named regions; trachyte and ‘red basaltic scoria’ or ‘red scoriaceous lava’ (also used as pukao or ‘topknots’ that were placed on the heads of about 75-100 statues).
There are only 20 statues (portable and non-portable) now in the EISP database which were carved of basalt. Of these, 7 are in museum collections. The British Museum holds two basalt statues, both of which are of central and very great significance to furthering our understanding of Rapa Nui history. One of them (1869.10-5.1) is re-carved on its dorsal side with bas-relief and incised petroglyphs of great iconographic significance. This re-carving is unique in its style, detail, and expertise and quality of execution. Four other statues, including 1869.10-6.1 (Moai Hava), have incised petroglyphs of lesser distinction but within clearly defined, limited typological categories. Another 30 statues still in situ on the island have applied decorations of similar styles.
Support Sustainable Archaeology on Easter Island
Dear Friends,
In 1982, I established the Easter Island Statue Project. Through a methodical archaeological survey my Rapanui colleagues and I have accomplished the digital mapping of Rano Raraku statue quarry, documented over one thousand statues throughout the entire island and created the world’s largest archaeological archive describing the statues.
Working with scientific colleagues at The Cotsen Institute of Archaeology at UCLA and with conservators from Chile’s Centro Nacional de Conservación y Restauración, the first phase of our three phase project has been initiated. We are currently excavating and conserving two statues in Rano Raraku interior quarry of major archaeological significance. Knowledge gained there will allow preservation of other statues throughout the island.
In 2008, our work was rewarded with a major grant from the Site Preservation Task Force of the Archaeological Institute of America (AIA; www.archaeological.org).
This wonderful AIA grant has jumpstarted our conservation initiative. EISP has no endowment. Our only source of income is grants and U.S. tax deductible contributions. We also enjoy profit sharing through sales of contemporary indigenous art in our Mana Gallery on Easter Island.
Please help us match the AIA grant. Join us in A Monumental Task, Join us as a Friend of EISP!
