More about this marker. Although the marker references El Tejon Parlor No. 239 NSGW, El Tejon 239 is a parlor of the Native Daughters of the Golden West (NDGW). How the ones who placed the plaque allowed this to stand is anyone's guess.
This location was plaqued as an E Clampus Vitus historical marker in October of 1963, but that specific marker is no longer there. The location of the 1963 marker can be seen in the 2011 photo, the white concrete spot on
the right.
In 2012 E Clampus Vitus completely rebuilt and reset the base of the markers which had eroded away as can be seen in the 2011 and 2013 photos. They dedicated the latest granite and ceramic plaque, thus replacing the 1963 plaque at that time.
Regarding Walker's Pass. This site was designated California Historical Landmark No. 99 in 1932.
This site was designated a National Historic Landmark in 1961.
Statement of Significance:
Named for Joseph R. Walker, a fur trapper and guide. Native Americans showed the still remote pass to Walker in 1834, and he led the first immigrant wagon train into California through this pass in 1843.
Note: Early map makers marked the wrong pass as Walkers Pass, and the mistake persists today. This is not the pass used by Walker.
