Physically it measures around long, and wide. It is in this place which the Ille Cave, one of the main archaeological sites, can be found. It is actually a network of 3 cave mouths located at its base.Paz, V., Ronquillo, W., Lewis, H., Piper, P., Carlos, J., Robles, E. Xhauflair, H. (2008).

Although excavations for this site have been done since 1998, according to UP-ASP, surveys and recordings have been done as early as the 1920s by Carl Guthe, in an attempt to record as many archaeological sites in northern Palawan as possible. This sparked the interest of Robert Fox (1970), but was also limited to recordings rather than excavations. It was only in 1990 that a full archaeological survey was made by the

Archaeological discoveries

Different archaeological evidences led to different revelations about the area. During the first excavation in 1998, the archaeologists were able to discover shell middens and human burials. Excavations in Ille continued in 2000 and 2002 at the west mouth and east mouth with deeper excavations. Evidence of

The cave has two main mouths facing the south: the east mouth and the west mouth. Both mouths have large trenches placed on them. Vegetation of mostly secondary growth trees surround and top the cave. The ground of the cave is mostly dry, but some areas are wet due to the water dripping down from the ceiling. Based on

s (from sherds found). There is an evident practice of cremation of remains, as both human and animal remains with evidences of burning were found a pit, making this the only evident "cremation cemetery" of this age, so far. An evidence of a complex burial ritual was also discovered. The ritual involves an elaborate process of defleshing and disarticulation of bones, crushing of (large) bones, and lastly, cremation and burial. As the remains were also found to be tightly concentrated and compact, it was suggested that it might have been placed in a container that decomposed later on.Lara, M., Paz, V., & Solheim, W. (2013).

pottery sherds were recovered from the site, amounting to approximately 12,600 pieces. Unfortunately, these finds cannot be confidently associated with any of the surfaces in the site due to turbation (postdepositional disturbance) of the layers where most of the sherds were discovered. However, some of the decorated sherds were traced back to 4000–5000 years ago, mostly red-slipped with impressed circular designs, with some circles filled white with either lime or clay. Other sherds were associated with the "Metal Period" (which was around 2500 to 1500 years ago in Philippine Archaeology) due to its designs with geometric forms (with some painted red), commonly associated with this period. Large pieces of undecorated sherds were also found that may have been fragments from burial jars. Majority of the pottery decorations are associated with Sa Hyunh-Kalanay pottery. Variations of the designs (in both technical and stylistic aspects) between the pottery from Ille Cave and other sites in Dewil Valley suggests that these may have been adapted from other traded pottery. Evidence of pottery firing have also been found in the Ille cave.Balbaligo, Y. (2010). Preliminary Report of the Earthenware Pottery from Ille Cave and Rockshelter, Palawan, Philippines. Hukay, 15, 1-20. While there are no primary jar burials in this site, Ille pottery would have probably played a vital role in burial practices of its communities of practice. Tradeware, although limited, were also found in Dewil Valley. Tradeware sherds recovered from the Ille platform were mostly brown stoneware,

epoch, there was an abundance of deer in the island. However, deer became rarer while the number of pigs increased during Mid Holocene based on the records from the Ille and Pasimbahan sites.(Ochoa, et al. 2014) said that "the increased number of pig remains and scarcity of deer in the middle Holocene middens of Pasimbahan also strengthen the observation that there is a clear shift from deer to pig hunting by the middle Holocene". Aside from faunal remains, plant fossils were also recovered from the different sites. Many plant remains such as seeds, wood fragments and plant tissues were obtained from the Pasimbahan – Magsanib site. After the sampling of archaeobotanical remains, results showed that "six out of the eleven plant tissues, seeds and nuts were found to be consistently transformed, either charred or probably mineralized state".(Ochoa, et al. 2014) The recovered seeds of ''

Stone tools

In total, there are more than 1000 stone tools discovered out of 50,000 artefacts recorded from Ille Cave— a part of Dewil Valley located in Brgy, New Ibajay, El Nido, Palawan— since the start of the excavations in 1998 under the direction of

y topsoil contained post-Neolithic artifacts which includes stone and shell beads. In the west mouth, some graves were found with stone adze which may date to an early phase. Stone adze was also one of the most significant artifacts found in the excavation in the southern half of the trench of the west mouth.(Lewis, et al., 2006) Aside from this, stone flakes were also found in Phase E, the habitation and cremation practice phase dated 8,000 to c.a. 10,000, of Pasimbahan site located within the Magsanib district of Dewil. In addition, the assemblage of artifacts discovered by the UP-ASP and National Museum in the deposit labeled Midden 2, one of the caves in the Dewil Valley which was first investigated for its archaeological material in the year 2007, were composed of mainly of stone tools, together with consumed animal remains and shell fish. Stone tools found in Midden 2 were cobble size stone tools associated with shell food remains, and pig bones. These finds negated the hypothesis that the deposits labeled Midden 2 were not actually an in situ assemblage of stones, bones, and shells.(Ronquillo, et al., 2008)


Cultural heritage

In the 1960s, Robert Fox (1970) headed a National Museum team that continued Guthe's work in northern Palawan; new sites were added to the list of sites first described by Guthe. A good number of these sites were from small islands located in Bacuit Bay. Of the sites Guthe surveyed, there were a few that National Museum excavated. One such site excavated in the 1960s was Leta-leta cave. Located in Lagen island, in the bay of Bacuit; the conclusion of the 1960s excavation led Fox (1970) to confidently describe the archaeology as a "Metal Age" burial site. The excavation was highlighted by the recovered unique earthenware jar with a mouth fashioned to look like a yawning/shouting person. This unique jar is now considered a national heritage artefact and displayed in the National Museum in Manila. The research and heritage work at Dewil has accumulated much information throughout its years of existence. In 2005 more artefacts were recovered at Ille in the form of pottery design and nephrite ornaments that reinforced the Mainland Southeast Asian connection of the site. In 2006 the excavation at Ille further expanded to include areas inside the cave itself. There were more artefacts recovered and the understanding of the

became clearer. Excavation on the southern half of the trench continued with the aim of understanding the nature of having Neolithic and Metal Period deposits at deeper levels compared to most of the area of the trench. Further excavation on these contexts yielded more materials such as pottery fragments and human remains. Some of the pottery fragments were found in concentration and belong to one vessel. Some of the most significant artefacts found in this square were a stone adze, a complete pottery pedestal base, and a ''
