San Bruno Mountain: Owl Canyon

April 16 @ 10:00 am - 2:00 pm

Owl Canyon is not as heavily forested as the adjacent Buckeye Canyon and is a bit more diverse with wildflowers. Owl has a pronounced central hump between each ridge line that makes the ascent up the canyon interesting and it still shows signs of the 2008 wildfire. Many oaks, bays, toyons, hazelnuts, ocean sprays, holly-leaved cherries, coffee berries and oso berries have stump-sprouted and eleven years later prove how adaptable they are to fire. The fire-reliant blue blossom seeds in the soil have created large thick communities on the canyon walls. Wildflowers to look for are larkspur, star lily, hound’s tongue, paintbrush, yerba santa, lupine, golden violet, blue-eyed grass, clematis and many ferns. We’ll have lunch on the flowering grassland ridge between Owl and Buckeye and hopefully see some colonies of blennosperma on the way down the ridge. Heavy rain cancels.
