Site of an archeological excavation in the mid 1970’s that produced a female skull, stone and metal tools, pottery sherds of Chinese, Thai and local origin. A fragment from the skull was dated 350 CE by the Scripps Institution of Oceanography in La Jolla, California.
Surface survey in 2003 found more pottery sherds, obsidian flakes, a Spanish coin, and a whale harpoon. In 2009, a gravesite containing 52 female and male bones of various ages was discovered. Local scholars, such as anthropologists Dr. Erlinda M. Burton and Dr. Antonio J. Montalvan II, believe Huluga is an ancient settlement described in Spanish documents as Himologan.
Currently the site is under threat from urban development, treasure hunters and lack of support from the local government.
