Upper Oso Canyon to Nineteen Oaks

Date: Saturday, April 8, 2017

Time: 9:30AM - 2:00PM

Instructor: Susie Bartz

Location: Oso Creek

LOCATION CHANGED: Due to road and trail closures, this trip has been changed to Birabent Canyon: Hiking Across 100 Million Years

Come with Susie Bartz up Oso Creek into the Santa Barbara backcountry. We’ll see some amazing geologic exposures and hope to see how the land flowers after a fire season. On the way we pass along towering sandstone cliffs and navigate the conglomeratic boulders in the creek before crossing a major thrust fault. From there we encounter the rich colors and textures of ancient Franciscan rocks. Where did they all come from, and how did they get here? And why does this landscape evoke such a sense of violent upheaval? Consider some answers with Susie, and enjoy lunch at the Nineteen Oaks campground before returning to the trailhead.

This field trip is mostly within the area burned by the Rey Fire. As a result, the rocks will be newly exposed, and we’ll watch for consequent landslides and vegetation response after the winter rains. So any interested fire-following botanists will be most welcome!

NOTE: 4 miles round trip on a trail of moderate difficulty, including creek crossings and one short scramble up to the Nineteen Oaks campground. Participants should be in good physical condition with good balance.

Participants should bring:

  • Hiking poles
  • Sturdy boods with good traction
  • Lots of water
  • Bag lunch
  • Hat
  • Sunscreen

After college and graduate school, she married and came to Santa Barbara in 1974. She enjoys hiking and backpacking, and holds a degree in geology from SBCC. In 2009, she completed a project publishing the maps of legendary geologist Tom Dibblee, who was her personal friend and mentor, and in whose memory she dedicates her walks. As a geology educator, Susie works with schools and community organizations to bring an awareness of earth science to the general public in outdoor settings. She lives in Santa Barbara with her husband and assorted cats, and has two married daughters and three darling grandsons.
