From the Guidebook:
The Hay Tree is an old, 50
foot high camphor tree standing in the middle of a grassy
area in downtown Paramount. The tree is a rare remnant
of the city’s once thriving dairy and hay industry.
The towns of Hynes and Clearwater, which later incorporated
to become Paramount, were in the middle of Los Angeles
County’s extensive region of dairy farms that thrived
during the first half of the twentieth century. Hynes-Clearwater
was the “Hay Capital” of the world from about
1930 to about 1960. There are no other properties in Paramount
that are linked to the hay industry except for this tree.
