Who We Are

The NCGS is a non-profit organization affiliated with the Pacific Section of the American Association of Petroleum Geologists (AAPG). We meet on the last Wednesday of the month, and more details can be found here. The Society’s objectives are to promote the scientific and educational aspects of geology, to foster fellowship and cooperation among earth scientists, to increase the public’s understanding of earth science applications in our daily lives, to recognize the responsibilities of geoscientists to society, and to promote honesty, integrity, and professional ethics in the geoscience community.
