ABSTRACT
The year of 1933 ended, and 1934 began memorably in Los Angeles County. The memorable event - a classic example of alluvial fan flooding in La Cañada Valley-was not a regional crisis (indeed it was highly localised) but it acquired a significance well beyond its area of damage. There are relatively few scientific accounts of it, but that by Troxell and Peterson (1937) is outstanding. Unless otherwise stated, most of the details in the following description are drawn from their study; other major sources include the work of Eaton (1936), Kraebel (1934), Taylor (1934), and Chawner (1935). There are some inconsistencies in the data in these papers, but they are not serious.
