Spring is a prime time to observe lichens, bryophytes and terrestrial algae with John Villella, a botanist with the Siskiyou Biosurvey and member of the American Bryological & Lichenological Society. Some lichen highlights include variant forms of Xanthoparmelia and Dermatocarpon, and local rarities such as Parmelina and Peltula. The hike is free, but registration is required: https://lichen-hike-2019.eventbrite.com.
Hikers will meet at the trailhead for a 2.5–4.5 mile round trip hike up 800 feet along a moderate grade trail. Participants should dress for the weather and terrain and bring water and snacks since hikes to the top may last 3 to 4 hours. Restrooms are available only at the trailhead; there is no drinking water. Due to limited parking at the trailhead, carpooling is encouraged. To help protect this special place, dogs and vehicles are not allowed on the trail.
