Bedrock mortars at Chitactac-Adams Heritage County Park. People used these to grind foods for thousands of years here as this particular area was inhabited for at least 3,000 years and probably longer. The mortars are right there to appreciate on a walk around the park. There are so many in various spots. I enjoy thinking about these, and the people who used them, and their descendants living in the Silicon Valley and other places today.

SLAC – Longest Linear Accelerator
Looking down the hall of the 2 mile long straight building at Stanford’s linear accelerator. Straight, not level. The guide said if it was level it would follow the Earth’s curve and at 2 miles long it would then be about 12 inches off of straight at the end. This building was designed to be straight because a couple of stories below ground, under this support equipment that the building is housing, is a long tube that is designed to accelerate particles very near the speed of light. And those particles go straight. You don’t get too many opportunities to look down so perfect an example of a diminishing perspective through distance.
This is the outside of the building, looking down the exact same stretch as seen in the inside photo above it. You can see highway 280 going over the linear accelerator as a bridge not too far ahead in the photo.
Our tour guide took us to a newer building added down the end of the accelerator where x-rays generated by the accelerated particles are used for modern research. The accelerator was running throughout this whole visit, and does so through most hours of most days of the year. And so, behind the tour guide in the above photo, here a few stories under ground, x-rays are flying through the labs in a horizontal tube that I pointed out with the added blue arrow. These x-rays are used in the various experiments going on in the numerous rooms of SLAC.
There is something wonderful about humans working together on huge ambitious projects to advance our understanding of the universe. And it is pretty great to get to look at these projects and to consider what they do and how they do it.
Coming back up to the surface, surrounded by California.
Flip Phone Pix
Here are some fun with a flip phone photos from in and around San Jose. These photos have no added filter effects; this is just how cell phone photos use to look. They are less than 2 megapixels and sometimes look a little like computer generated paintings and sometimes like incredibly detailed versions of foggy dreams.

A Well Used Post
So many signs have been here.

The Box on Mt. Umunhum
All cleaned up. Can not go inside still, but you can touch it now. It’s no longer behind all of the barrier fencing that had been up for quite a while. Same great views of the valley and a new paint job for the box.
San Jose view from above
From up on Mt. Hamilton, you can see a lot. Hard to see in my photo, I know. However, the left of the photo above shows San Jose and at right of middle shows San Francisco amongst much more. Its easier to see in person and so I highly recommend visiting. Drive safely and slowly as the road to the top is winding, includes many rocks and dirt patches, and is a favorite for impressive bicyclists to conquer.
South San Jose is in the right of this photo above and Monterey is in the center in the distance.
And when you are ready to go inside the Lick Observatory from atop Mt. Hamilton, you can see this gigantic telescope from 1888, among other modern telescopes at the observatory.
