Fluvial Processes in Geomorphology & How the Flora Responded to a Devastating Debris Flow in Buckeye Canyon, December 31, 2022

Leaders: David Nelson and Doug Allshouse

Saturday, November 15,  10am-3pm

Fall is a great time to visit San Bruno Mountain even when most of the plants are “hibernating” and look at the Mountain with a new perspective. This hike will look at the geological history of the Mountain, the dynamics of the devastating debris flow that occurred on December 31, 2022. The debris flow in Buckeye Canyon and  wiped uprooted  all of the trees and wiped out all of the plants on the floor of the canyon. David and Doug are both CNPS YB board members and co-authors of the book: San Bruno Mountain: A Guide to the Flora and Fauna. This hike is part of the CNPS Yerba Buena chapter hiking program.

Meet at 10 am on Quarry Road at the base of Buckeye Canyon at the San Bruno Mountain Ecological Reserve. Bring water, lunch or snacks. Contact David at NelsonDL@Pacbell.net to register. Wear a hat for sun and take layers for possible foggy weather. Expect narrow trails and poison oak on trail edges along the route.

Directions:

1) From Bayshore Blvd, turn onto Valley Drive, the entrance to Crocker Industrial Park in Brisbane.

2) Drive down Valley Drive and turn left at the stoplight at the intersection of Valley Drive and South Hill Drive

3) Drive a very short distance on South Hill Drive; as the road begins to curve, immediately after a pedestrian crosswalk, you'll see a steep driveway on your left with potholes. Turn into that steep driveway and drive up. 

4) Immediately at the top of the driveway turn left and stop parallel to the concrete drainage ditch, next to the trailhead entrance sign to Buckeye Canyon. This is the location of the trail into Buckeye Canyon (Google Map)
