Geology of Harmon Canyon Preserve

Join the Ventura Gem and Mineral Society and geologist Tim Garvey for Geology of Harmon Canyon Preserve. You'll learn geologic concepts about the local “dirt” on which we hike.

Did you know that much of the strata exposed in Harmon Canyon is part of the thickest Plio-Pleistocene marine sedimentary sequence in the world? Harmon Canyon’s creek beds and trails reveal the folded, uplifted and eroded nature of this strata.

Did you know that the Ventura foothills lie within the Transverse Range geologic province, a province that has one of the only east-west trending mountain ranges in western North and South America, and has “uplift rates” that rival the fastest growing mountains in the world? Come learn!

This event is free and open to the public.
