The Center of California

2008-10-25T16:54:00.000-07:00

A family trip to the "Center of California" found this mark placed by the North Fork Chamber of Commerce and the School of Geomatics Engineering and Land Surveying at California State University, Fresno.

From the North Fork Chamber of Commerce website Historical Page:

Once upon a time... during the gold rush era, North Fork, California was known for its logging. But as time marched on, the town became legendary as the "exact center of California.

North Fork did not become an overnight sensation, however. In 1972 the Madera Board of Supervisors, after hearing a rumor the Center of California was close to Madera, decided to locate the Center. Their grand plan consisted of building a monument to which visitors from far-away places could travel and admire.

But the city of Madera was disappointed after the survey was completed and the Center was found to be close to North Fork, some 40 miles east of Madera. A metal stake was placed in the ground, but, unfortunately, the only visitors to the spot were local townspeople. Soon, the Center was forgotten and the stake was inadvertently destroyed.

Through the years, North Fork townspeople would ask each other, "where is the Center?" But the passage of time has a way of dulling the memory. Soon, no one could remember.

In 1994 the North Fork History Group decided to do something positive about the Center. A County Sheriff Search & Rescue Officer brought his Magellan Global Positioning unit to the estimated area, however the equipment was not sophisticated enough to calculate the exact spot. Then the U.S. Forest Service arrived with their GPS equipment which uses mapping satellites to determine ground locations. They actually calculated to within a meter of the final calculations. Someone suggested contacting the Fresno State University Engineering & Surveying Department as they should have the most modern equipment available. CSUF was definitely interested in helping re-establish the site.

In May 1994, the work began. Old blaze marks were uncovered. CSUF students went back to Cal State Fresno to enter all the information into their computers while North Fork's townspeople anxiously waited ... and waited. There had been an equipment failure. More data was required. The waiting game continued as students graduated and summer vacation dispersed those involved.

Unexpectedly, Huell Howser of the PBS series, California's Gold appeared on the scene contacting residents of North Fork ... "why were there 3 different sites claiming to be THE Center of California?" Huell said he would like to come to North Fork in May 1995 to do a TV story about the "real" Center. The people of North Fork knew it was time for ACTION!

Another call to CSU Fresno brought new results! A graduating student, Leonard Gabrielson, materialized to complete the crucial computer calculations as his senior thesis. Huell called to confirm the taping date. The townspeople panicked! They were still awaiting the final word from Gabrielson as to the exact point. Fortunately, the very night before Huell arrived, the townspeople were called by CSUF with good news: the Center had been re-established by Gabrielson. Using their most recent technology he was able to pinpoint the "exact" Center. Everyone else involved, including the U.S. Geological Survey, verified the calculations. The show could go on! Huell & crew arrived and townspeople, as well as members from the various organizations involved in the search, were interviewed.

And so, the story was taped and everyone lived happily ever after...

Except, the other areas claiming to be the Center of California! One was at South Avenue 11 and Highway 99, a pine tree and palm tree, denoted equal distance of north and south on Highway 99. Bob Thomason of CalTrans, whose major efforts saved the trees from destruction, stated the person who originally planted the trees was unknown even though a thorough search had been made.

Another site was claimed by the town of O'Neals (12 miles south of North Fork). People there tell of old-timers who remember seeing a marker saying "Center of California" in a field ... but none could remember where.

For some, the mystery lives on. For the townspeople of North Fork, they proudly state that a few miles from the center of town, is the "exact center" of California.

A NOTE OF INTEREST A point was made by USGS's Alan Mikuni, that back in 1930 when technology was not as advanced as the present, someone had determined the Center by taking a cut-out of California and placing a point on the cut-out where it would maintain a balance. Amazingly, this point turned out to be very close to the re-established current Center!

Latitude: 37°22.786' N
Longitude: 119°23.740' W

I found this mark along the Sierra Scenic Byway. It was indentified as a U.S.Bureau of Public Roads mark, stamped with a date of "1952". Additional stamping included a project station of "636+01.52", a benchmark elevation of "4597.35", and "21.13", possibly a mile mark.

I had never seen a mark placed by the U.S.Bureau of Public Roads, let alone heard of them. A quick internet search found the following:

The Federal Highway Administration (FHWA) was created on October 15, 1966, however it has several predecessor organizations and a complicated history. The first predecessor was the Office of Road Inquiry (ORI) founded on in 1893. In 1905 that organization's name was changed to the Office of Public Roads (OPR), and it became a division of the United States Department of Agriculture. The name was changed to Bureau of Public Roads (BPR) in 1915. In 1939 the name was changed to Public Roads Administration (PRA) and it was shifted to the Federal Works Agency (FWA). With the abolition of the FWA in 1949, its name was changed back to BPR and it was shifted to the Department of Commerce. In 1967 the BPR was transferred to the newly created FHWA, and was one of three original bureaus along with the Bureau of Motor Carrier Safety and the National Highway Safety Bureau (now known as NHTSA).

GU1670 - An Important Mark, in a different way than most

2006-12-08T15:03:00.000-08:00

Until recently, I was employed by a Civil & Survey engineering firm that was the contract engineer for the City of Coalinga, California. As the 'field guy' for the acting Engineer, I was fairly familiar with the local benchmark network. A few years ago, I was given the task to map a portion of State Highways 33/198, about 1.4 miles long, through the town of Coalinga. It was an infrastructure project for curb, gutter, sidewalk (etc.) improvements. During the project, I tied into multiple city benchmarks and other various benchmarks within the project area. Four of the 'others' are in the NGS database - AH5203, GU1673, GU1670, & GU4200. AH5203 - COALINGA RESET, at the north end of the project, was destroyed by the DOT while building a new bridge. (According the one of their surveyors, it is to be reset, again, by them.) For obvious reasons, it was not tied into. GU1673 - J156, is the main benchmark for all the vertical control in town, and was adjacent to the roadway and well within the project area. GU4200 - INTERSECTION, is a street centerline monument in a well, also well within the project area. GU1670 - G944, at the south end of the project was not located, and consequently, not tied into.

GU1670 was a standard brass disk set in a round concrete post. It was set on the side of the road, across from the old fire station behind a curb. It was reported as 'found' in 1984 and then 'not found' in 1985, and for all intents and purposes, it should have been there as no improvements have been done in the area in some time. I couldn't find it as part of the project, but the benchmark hunter in me kept looking. I went back multiple times over the next few years, kicking dirt and looking in the logical and not so logical places, with no luck. This site probably had the most visits by me for any mark I've looked for without finding anything.

As I mentioned at the beginning of this thread, my employment has recently changed. My present employer has a collection of surveying equipment and artifacts on display throughout the office. Last week I was speaking with one of the other employees (relatively new to the survey industry) about the purpose of benchmarks and their markings. I was using one of my employer's display benchmarks to show him what I was talking about. During our discussion, the designation of the mark caught my attention; 'G944 1958'. The '944' was familiar - there was a '944' series of marks around the Coalinga area, set in the late 50's. I routinely used 'Y944', north of Coalinga, as a calibration point for my survey-grade GPS. I searched the NGS database for G944 in the State of California and only got one hit - it was GU1670. After nearly four years of searching, I found the brass disk I'd been looking for, more than 75 miles away.

Now, for the rest of the story....

Flash back to 1987. I was studying Architecture at a local college and got hired by a Civil & Survey engineering firm as a draftsman. This was before computers and CAD; all the plans and maps were drawn by hand with pen & ink. I was hired because of my drawing ability and penmanship, not because I knew anything about surveying or engineering. I honestly didn't know what either a surveyor or civil engineer was, let alone what they did. As I drafted the maps and plans, I would ask about things I saw or drew onto the plans. Over time I found that I was more interested in the surveying portion of my job over the civil engineering portion, and the architecture I was studying for that matter. (That interest in surveying is still there, nearly 20 years later. The architecture is all but forgotten.) I routinely asked the chief surveyor and the lead crew chief questions. I remember posing the question 'what is a benchmark?' to the lead crew chief. He explained it to me using an old brass disk he had on his desk that he used as a paperweight.

Now, flash forward to last week. My new employers are the same chief surveyor and the lead crew chief I worked with back in the 80's. About seven years ago, they cleaned out their desks and went out on their own. Now I'm back with them. GU1670 was in their small collection. When I told them that I'd been recently looking for that mark, one of them, the old lead crew chief said 'Really? I used that thing as a paperweight for years!'
