Gualala Arts Lecture Series presents:
Rock Formations

with Erik Olsborg
Monday, January 10, 2011, 7:00 p.m.
Admission is $5

Erik Olsborg Anyone walking along the Sea Ranch Bluff Trail or in the Gualala Point County Park has noticed the unusual layered rock formations and the impressive sea stacks just offshore. Now Erik E. Olsborg, in the first talk of the 2011 Gualala Arts lecture series, will unravel the geological story of the Marin, Sonoma and Mendocino coastline on Monday, January 10, 2011 at 7:00 p.m.

Mr. Olsborg will discuss peninsulas, arches, sea caves, rock bedding, faults and collapsed sea caves with a particular emphasis on the Salinian Block formations, those west of the San Andreas Fault.

To clearly illustrate his points he will use photographs of various project sites throughout the area. The story he will tell started millions of years ago, but is still being played out today. It is an intriguing one for those who know what to look for and this talk should provide some of the tools needed to witness that story and to make cliffside strolls more interesting.

A certified engineering geologist with over 37 years of experience, Mr. Olsborg provides engineering geology, geotechnical engineering and construction observation and testing services for residential, commercial and government agency projects. Mr. Olsborg has performed bluff studies on the Mendocino Coast since 1997. He has also performed coastal studies on the Sonoma and Marin (Tomales Bay) County coasts since the early 1980s.

His talks should appeal to those with an interest in geology and the weekend visitor alike. There will be opportunities to ask questions about the formations and about their effects on projects past and present. A $5 admission will be collected at the door.
