Abstract
In this report the area mapped north of the San Gabriel Mountains in the Lang and Humphreys Quadrangles is considered primarily from the structural point of view. A portion of this area at the head of Tick Canyon was mapped by Y. Bonillaas in 1933. During the year 1934-5, Mr. C. Dawson and the writer extended this work independent of the other.
W.S. Kew in Bulletin 753 of the U.S.G.S. has described much of the geology of the area. O.H. Hershey has described the Escondido formation outcropping in Tick Canyon, in the Amer. Meol. Vol. 29, p356. Brief descriptions of the borax deposits in Tick Canyon are found in Econ. Geol. Vol. 16, 1921 and U.S.G.S. Prof. Paper 158, 1931.
