22-Oct-1999 -- The N37 W121 confluence lies in a cattle ranch in the foothills of northern California's Diablo Range, adjoining the Central Valley. Despite lying in a sparsely populated area, this confluence is fairly easy to reach, as it's close to the junction of two major highways (CA-152 and I-5).

Starting from the truck stop on CA-152, we drove south along winding dirt roads, through vineyards and orchards. Eventually we met up with a gravel road (Pioneer Road), which led to a locked gate (picture #6 below), where we had to park our car.

At this point we were about a mile from the confluence, and were preparing to hike the rest of the way, when we remembered - we had our mountain bikes with us! So instead we were able to ride our bikes the rest of the way.

Using a combination of ranch roads and singletrack trails, we could ride to the base of a small hill, just 400 feet from the confluence. At this point we left our bikes and hiked up the hill. The confluence is near the summit of this small hill. We took a series of photos (pictures #1 through #4) forming a panorama. The whole area is dry rolling grassy hills. (Picture #5 shows our two GPS receivers at the confluence.)

It turns out that an easier way to reach the locked gate would be to take Pioneer Road all the way from CA-152, starting just east of its junction with I-5.
