Field trips to collect rocks, minerals and fossils are available to club members from a variety of sponsoring organizations. First, the club itself sponsors trips to local areas that can be visited as a one day excursion. Second, the club belongs to two organizations, the North Bay Field Trip committee and the California Federation of Mineralogical Societies, which sponsors collecting trips to more distant sites, that are often are multi-day excursions. Lastly, small groups of club members have impromptu trips to the Clear Creek Management area for agates and various minerals that occur during the cooler months. Before any of these trips, participants are briefed on the collecting and safety equipment needed, the degree of physical effort required, and the types of vehicles appropriate on the approach roads.
