This week we explored the serpentine soils of Mt. Tam located north of the bay in Marin County. We hiked up to the serpentine area from one of the higher parking lots and learned a bunch of new plants.
The serpentine soil had a shiny blue-green color due to the extra heavy metals that were inside of it. It limits what plants can grow and causes these patches of shrubs amongst the douglas firs.
This beautiful manzanita is native to only this area of serpentine soil and found nowhere else! It pretty much dominated most of the serpentine areas.
Near the parking lot was this awesome view of the hills behind the Golden Gate Bridge that is kind of hidden in this picture. Highway 1 is to the right, the city is straight forward, and the bay is to the left of this area. So pretty!
