A watershed is a geographic area that contains all of the rivulets and streams that drain into a river, river system, or other body of water, (in this case, Long Creek.) The ridge of land right here divides the Long Canyon watershed from the Cache Creek watershed, and it is called a water parting. Go over to the top of the saddle and you view the Napa/Yolo county line, looking off to the North.
There is always a nice breeze blowing over this ridge. The view looks just like hillsides of chaparral melting off into the distance, but an old-timer I talked to said that elk sometimes come out of Cache Creek and over this saddle into Long Canyon in their endless wanderings.
To log this cache, take a look at the two rusty old stoves, and write down the numbers on the top of either one. They look like dates. Then go ahead a log this when you get back home, but be sure to fire off an email to me, or I will be forced to delete your entry. No need to wait for confirmation.
The Top of the Watershed can be logged as a locationless cache by providing the GPS coordinates from your regional top of the watershed, a picture with your GPSr in it, and a small gif. or jpeg. of the topo map of the watershed, or part of the watershed including the top. Maps can be found at web sites like www.topozone.com.
