Mount Pierce (California)

Mount Pierce, sometimes called Pierce Mountain[2] or Monument Peak[1] at 3179 ft (949 m), is the highest point of the Monument Ridge which is part of the Coast Range in Humboldt County, California. It was named after U.S. President Franklin Pierce (1804–69).[3] The summit offers a wide view of a wide area in Humboldt, Mendocino, Trinity and Del Norte counties north to the state of Oregon.

Due to the high visibility of the top of Mount Pierce and the inability to see Mount Diablo from the northwestern corner of the state, a new principal meridian, the Humboldt meridian was established in 1853[4] intersecting the survey base line at the summit of Mount Pierce which still governs the surveys in the northwestern corner of California.[5]

The summit of Mount Pierce was marked with a tower of iron bars, now gone, but currently noted by an array of antennas, a geodetic marker and a plaque, placed on October 4, 2003 on the sesquicentennial of the establishment of the Humboldt Meridian Initial Point by Deputy Surveyor Henry Washington on October 6, 1853.[6] The center of the Initial Point is marked by a standard US Coast and Geodetic Survey triangulation station disc, stamped “Mt. Pierce 1928.”

Humboldt Meridian Initial Point - Established by Deputy Surveyor Henry Washington - October 6, 1853 - At this location, on October 6, 1853, Deputy Surveyor Henry Washington established the Humboldt Meridian Initial Point. All future surveys in Northwestern California would originate from this point, north to oregon, east into Trinity County, south into Mendocino County, and west to the Pacific Ocean. From this Initial Point, Townships and Ranges were laid out, six miles to a side, and further split up into square miles. This Initial Point is one of three in California, and one of 37 in the United States. This plaque, dedicated on October 4th, 2003, commemorates the sesquicentennial of the Humboldt Base and Meridian Initial Point. Triangulation Station Mt. Pierce 2, established in 1928, now resides at the site of the original point, which was a tower constructed of iron bars believed destroyed by lightning.
