The Tick Canyon Formation (Tt) or Tick Canyon strata, is an Early Miocene geologic formation in the Sierra Pelona Ridge of the San Gabriel Mountains in Los Angeles County, California.
[2] The Tick Canyon Basin drains into the Santa Clara River.
[2][4] The Tick Canyon strata was deposited on land mostly by streams and consists of green sandstones, coarse-grained conglomerates, and red claystones.
[4] North of the Tick Canyon Fault, the beds are almost vertical.
[2] It preserves vertebrate fossils of the Lower Miocene subperiod of the Miocene epoch, in the Neogene Period of the Cenozoic Era.
