Southern California Botanists

The Pinnacles. Date To Be Determined. Leaders: Duncan Bell and Justin Wood

The Pinnacles are a great hiking and rock climbing area located just north of Lake Arrowhead in the San Bernardino Mountains. The trailhead is accessed via State Route 173 from either Lake Arrowhead to the south or Silverwood Lake to the west. It is located in a diverse transition zone between the yellow pine forests to the south and the Mojave Desert scrub to the north. The area is dominated by chamise and manzanita chaparral. During the trip we will explore an area dominated by large granitic boulders and outcrops, we will venture into some of the adjacent drainages, some recently burned chaparral, and will try to visit at least one seasonal meadow. During the trip we hope to see several special-status plants including Palmer's mariposa lily (Calochortus palmeri var. palmeri), Latimer's woodland gilia (Saltugilia latimeri), bluish spike moss (Selaginella asprella), and San Bernardino Mountains liveforever (Dudleya abramsii ssp. affinis). We are still developing the details of the trip so please e-mail Justin Wood at Jwood (at) if you are interested in attending or keep a look out for social media posts about the trip coming soon.
