I have long been interested in modern and ancient alluvial fan deposits because they are directly linked to contributing watersheds and, thus, convey information about tectonic and climatic influences on sediment production and transport. I have studied Pleistocene-Holocene alluvial fan deposits in Death Valley, Walker Lake, Panamint Valley, and the Imi'n Tanout region of Morocco.  I have an extensive database on early Jurassic alluvial fan rocks from the Hartford basin (Conn-Mass.) as well as other Pangean-breakup rifts.   I am currently using previously unrecognized alluvial fan rocks in the central part of the Hartford basin to describe the existence and location of incipient sub-regional half-graben formed during an early stage of basin evolution.
