For over 25 years I have been documenting the ancient Hawaiian sites of Nāpali with large format Black & White film. As this is still the only time proven archival photographic media. 
The project has been to document the ancient Hawaiian sites located in the worldʻs second fastest eroding area for future generations. Images from this project have been used in 2 Kauai Museum exhibits as part of "Preservation through Education" program.
Presently the first book "Miloliʻi" in the series on the land divisions of Nāpali is being published in January of 2019.
