Chapman Ave., then right on Bradford Ave [total driving time 5-10 minutes].

Field Trip to Santa Catalina Island SATURDAY, JUNE 27 The field trip will be to Santa Catalina Island, and will be led by Professor Doug Eernisse. We will observe wildlife, including subtidal mollusks, on the way to the island. Once on the island, you can choose one or more of the following activities: snorkel, kayak, hike in the hills, visit the USC Wrigley Marine Center and touch tank, and have a picnic. The $25 fee for the field trip includes lunch as well as docking fee and rental costs of snorkeling gear (including wetsuit) and kayak. Those who have already paid the $50 field trip fee will receive $25 back or you can elect to sponsor a student. Notes on the boat trip: there will be some rocking and rolling, so if you get motion sickness at all you should probably take motion sickness medication before the boat trip to and from the island. Also, make sure you bring appropriate shoes, as no open-toed shoes or sandals are allowed on the boat. In case of emergency you can contact Michael Vendrasco or Doug Eernisse via cell phone (MV: 562-645-2644; DE: 714-747-2048). DEPARTURE SCHEDULE 6:00 AM - depart from CSUF at the loading dock of the DBH building on its west end, with free parking available in nearby Lot C. OR 7:00 AM - meet at the Southern California Marine Institute (Terminal Island near City of San Pedro). Directions are at the bottom of this page, map on following page. Vanpool: If you registered and paid for the field trip by May 30, you are guaranteed a spot in the vanpool. If you would like to ride in the vanpool or can offer a ride, let Michael Vendrasco and Doug Eernisse know. Late registrants wishing to ride in the vanpool will be put on a waiting list.

5:00 PM – Back on mainland.

DIRECTIONS TO SOUTHERN CALIFORNIA MARINE INSTITUTE (from campus, take I-57 about 1.5 miles south to I-91 West, then drive 22 miles to the 110 Harbor Freeway south, and follow directions below)

FROM THE 110 HARBOR FREEWAY Take the 110 Harbor Freeway south towards San Pedro. Exit at Rt. 47, the Vincent Thomas Bridge. Cross the bridge and exit at Ferry Street (the first exit coming down off the bridge), and turn left (onto Ferry) at the signal. Turn right onto Terminal Way (second signal). After one signal and two stop signs, the road curves left and becomes Seaside Avenue. After the curve, you’ll see water on the left, after which SCMI is the first building, a tan two-story with a reddish fence along the street. Public parking is on the street (east side only). FROM THE 710 LONG BEACH FREEWAY Take the 710 Long Beach freeway south to Terminal Island (right two lanes when freeway splits). Then continue on to the Gerald Desmond bridge (Ocean Blvd) by staying to the left. Cross the bridge, continuing on Ocean Blvd then exit at Ferry Street about 3 miles (just before the Vincent Thomas bridge, which you don’t want to cross). The offramp will turn left under the bridge onto Ferry Street. Continue on Ferry, and at the third signal turn right onto Terminal Way. After one signal and two stop signs, the road curves left and becomes Seaside Avenue. After the curve, you’ll see water on the left, after which SCMI is the first building, a tan two-story with a reddish fence along the street. Public parking is on the street (east side only). See map on following page.

SOUTHERN CALIFORNIA MARINE INSTITUTE (SCMI) 820 South Seaside Ave., Terminal Island, CA 90731.

Modified Google Earth image showing location of SCMI, for trip attendees who wish to drive themselves to harbor. Map width = 1.25 km. HINTS FOR FINDING SCMI IF YOU GET LOST:  Stay on Terminal Island - between the Vincent Thomas Bridge and the Gerald Desmond Bridge.  The Terminal Island Correctional Institution, and the Coast Guard are past SCMI on South Seaside Ave. So follow any signs to these that you see. If you reach them, you have gone too far. If you are lost ask for directions to these two landmarks!  Call Mike or Doug or SCMI at (310) 519-3172.

CSUF Campus Map Talks will be held in KHS (Kinesiology and Health Science) 199. Workshops, the opening reception, and the auction and reprint sale will be held in MH (McCarthy Hall) 237. If you find yourself on campus with nothing to do for a few hours, the Fullerton Arboretum is a nice place to visit. Parking is free in the dirt lot right outside the Arboretum (NW corner).
