Superb new three dimensional exposures of the Miocene Lower Capistrano Formation near Dana Point, Southern California, show all the principal depositional environments of the upper parts of a deep-sea fan. Thick, massive, coarse sands deposited on the suprafan pass up into sands deposited in a shallow channel flanked by silts. Large blocks of these silts periodically slid into the channel. Later, a deeper channel with steep walls was cut through the silts, and was filled with sands. The channels are comparable to deep-sea fan-valleys. The whole succession shows a progression from more distal to more proximal depositional environments. The effect of various scales of channeling on turbidity current deposition can be seen.
