Big Bear Solar Observatory

Backround info: The Big Bear Solar Observatory is (currently as of April 2019) the largest solar observatory in the world. The observatory is run by the New Jersey Institute of Technology with other parties taking an interest (funding) such as NASA, USAF (Air Force), and the NSF (National Space Foundation), etc.
Aaron and I honeymooned  in Big Bear back in 2005,where we stayed at this charming bed and breakfast called the Star Gazer's Inn & Observatory. On the week we booked, they had a retired astronomer come in and do a one hour presentation before they let us loose on the telescope. It was quite a magical experience we never forgot.

When we finalized plans on coming down to California for two months, we knew we must go back and visit the inn. Sadly, after doing a bit of research online we found out it had shut down a number of years ago.

We decided to still go spend a day up in Big Bear. When researching points of interests, we came across the Big Bear Solar Observatory. And they do one public tour each month, which happened to be in two days from when we discovered the tour's existence. I got us booked minutes later.

Although quite a different adventure from staying at the Star Gazer's Inn & Observatory, It was still an amazing experience.

When we first approached the gate entrance to the observatory, we noticed that the observatory was on the lake. Yes, they built up the land in order to keep the telescope cooler than it would be on the main land. Our guide, Vasyl, gave us a history on the observatory mentioning that they originally had to row boats out from the mainland to get out there, before they built the causeway connecting the main land to the observatory. Unfortunately, several earthquakes had devastated the walking path, so they have been forced to rebuild it several times over the years.
On the property, there were two dome structures and a third metal shipping container that housed other telescope equipment. The  shipping container and smallertelescope were gated off, but Vasyl mentioned it was monitored by the GONG organization (Global Oscillation Network Group) & the US Air Force. 

The smaller of the two domes was opened, so we could see the interior,  but was not large enough to accommodate the tour group size. It looked to be out of commission at the time of our tour.

After fifteen minutes of being in windy, frigid weather, we all crowded into the main dome. The day of our tour, it had been overcast, and disrupted the daily observations of the sun, which was a bit of a disappointment. They had been observing the sun for a partner science program's rocket launch to provide comparative data. One of the astronomers, John Varsik, had programmed an algorithm, which automatically closes the dome in the event of cloudy skies, of which there is no manual override. The dome had closed minutes before the rocket launch and a few hours before the tour began.

Even though we weren't able to view the telescope in action to see live imagery, we still had a great time viewing the equipment and interacting with the scientist. One of my two favorite scientists from the trip were John Varsik who was an all around wizard. He was able to perform every position at the observatory. My other favorite was the main telescope engineer, Claude Plymate. He was a pretty eccentric guy, but seemed equally as sharp. His academic background was astronomy, but he also wore more than one hat. His job description seemed more electrical/mechanical engineer.

Aaron and I had a fun time checking out the electrical wiring and bussways, as well as attempting to figure out how things work. It was definitely a great learning experience.


The gold plated box on the right was the 'Sarcophagus', which housed the delicate photoreceptor sensors for the telescope. In order to view the sun through the earth's thick atmosphere, they have to cryogenically cool it to extremely low temperatures, to isolate the sensor's surroundings from any temperature abberations. The cryogenic equipment is to the left. - Aaron
The control room housed many monitors which the staff used to keep an eye on the equipment. This is one that monitored the exact positioning of the mirrors so that the light would be positioned properly on the photoreceptor equipment. - Aaron

In the list of top 10 deepest lakes in the world, Crater Lake is pretty cool for several reasons. In addition to this lake being in a volcanic caldera (a crater-like hole that forms after a volcanic eruptions leave the ground deep underneath unstable and unsupported).

It's also a lake with no connected sources (streams, etc). So that makes it crystal clear. Interestingly, there's actually a way to measure the clarity of a body of water: the Secchi disk:

By the time we made it to the Redwoods, we had already been on a whirlwind tour visiting Yosemite National Park, Sequoia National Park, and a number of national forest and state parks. Between the long drives, lack of sleep, and altogether crankiness of the four of us, we were less than excited about seeing more trees.

On the drive through the hills on the way into Yosemite Valley, you can see some of the recent wildfire devastation. There were a few places that had been setup with what looked like makeshift lumber mills, each having large stacks of charbroiled logs piled high. They maintained sprinklers on them to keep them wet, for some reason. I couldn't find that I took any pictures of these burnt log mills. Not sure if they can still salvage some of the wood deep inside the logs, if they grind them up for sawdust, or just stack the logs out of the burned zones to remove any future wildfire fuel.

Sequoia National Park and Kings Canyon Park are lesser known parks compared to their northern neighbor, Yosemite. Although they lack the grandeur of Yosemite's rock formations and waterfalls, Sequoia National Park is still pretty magnificent in its own right.

The park is set up on a half loop, encompassing over 400,00 acres with an elevation climb from 1700 feet to the higher elevation points of around 7000 to 8000 feet with varying biospheres by elevation. From start to finish, it was by far the most diverse park we have been to, yet.

Death Valley has plenty of living things. Campgrounds, resorts, swimming pools, restaurants, and more tourist amenities can make it quite the opposite kind of experience that its name would suggest.

But the landscapes are probably the main attraction in this place. It feels like the closest thing you can get to standing on a desolate Martian landscape. Many of the photos you could take here, resemble those sent back from the Curiosity rover.

Not being huge fans of hot weather, we decided to do the whole trip in one long day. Which probably was a mistake, because there were so many things to see that we hurried from place to place, spending much of the time driving between viewpoints, hiking trails, or other destinations. I could easily spend another couple days seeing things that we passed by, and hiking some of the longer trails. It's a big place. The entire park comprises nearly 3.4 million acres. It's more than 4 hours just to drive from one end to the other, which you'd never actually do. You loop around the park, meandering in and out of different areas.

Here are the highlights:

Four months late, but Trek Tales is officially up.  We named it after our RV, a 1997 Safari Trek (class A motorhome).

We won't be able to write about each and every day's event, but will cover the highlights and points of interest. We're hoping to get at least one post up a week.

Also,  you can view our map to see where we are currently at.

We hope you enjoy the Trek Tales!

Six Flags was something I've wanted to do since I was a kid. It sets itself apart as a theme park for roller coaster enthusiasts. While every other park has an over-arching theme (Disneyland, Universal Studios, Knotts, etc), Six Flags just tries to have the biggest and baddest rides.

The entire experience of the day can thus be easily broken down to each thrill ride:
