South west from Bishop.
This is the GoogleEarth view looking North, Bishop in the distance, Big Pine is about 15 miles south of Bishop on Hwy 395 (right side of image).
This GoogleEarth image is looking South (180 degrees from the 1st image).
There's the two switch backs.
Give the
Bishop BLM Field Office a call (phone number at the bottom of that web page). If they don't know, they should be able to give you the number of someone that does know about the condition of the Cayote Flat Road.
A lot of MC & ATV guys like to go up there to ride.
Can be noisy, but, it is a big area to boondock in.
I haven't driven or taking my MC on the road up there in many years.
But, I remember the switch backs as being OK, if the road has been graded.
They are on the first part of the climb and are so close to each other that you could walk (or ride an MC or ATV) to them and check them out before you get too far up.
Back in the day the dirt runway was known as the Coyote Flat International Airport.
Land heavy, take off light.
My sister that lives in Bishop says none of that happens anymore.
I was at South Lake and Sabrina Lake, a little lower in altitude, a few weeks ago.
Days were in the 80's, nights in the 50's.
Hope the weather holds nice, as it can really blow up there.
