Bishop Peak is a 1,546-foot (471 m) volcanic plug in San Luis Obispo, California. It is the tallest of the Morros or "Nine Sisters", a chain of similar peaks stretching to Morro Bay. Often said to take its name from its resemblance to a bishop's miter, it is named in homage to the town's name (San Luis Obispo). "Obispo" is the Spanish word for Bishop.
Geology
Like the other Morros, Bishop Peak is primarily composed of dacite. About 20 to 25 million years ago, magma welled up underneath a layer of softer rock and solidified. The softer overlying rock has since eroded away, leaving a distinct rugged shape.[5]
Wildlife
Bishop Peak's thin, rocky soil supports many plants that are not common in the surrounding area. Vegetation includes an Oakwoodland, sage scrub and chaparral.
Quarrying has taken place as far back as 1890. Granite for the nearby city of San Luis Obispo can be found along curbs in most of the city's older neighborhoods and on several extant structures, most notably, First Presbyterian Church.
Bishop Peak Natural Reserve includes 350 acres (1.4 km2) of land purchased or donated since 1977.
There are many access trails that rock climbers use regularly on Bishop Peak to access different climbing walls. One of these trails, the 'Oh Man' trail starts just to the left of the cracked wall, which is off of the Highland or Patricia Drive trailheads, and it can be taken as an alternate route to the summit. It was named the 'Oh Man' trail due to the fact that it is a short, springy trail and it must be taken at a steady tempo in order to maintain safety. It is rated a Scramble Class 4, but it is off of the main trail, and therefore access is currently closed.[citation needed]
