Location The Hanford Brook area is about 25 mi (40 km) northeastof Saint John, near the boundary between Saint John and Kings Counties. It can be reached by New Brunswick 111 and 820 from Saint John or by New Brunswick 111 from Sussex, which isabout 22 mi (35 km) to the north. The site (Fig. 1) is reached via a driveway, on the north sideof New Brunswick 111, that is about 0.9 mi ( 1.4 km) south of thebridge across Hammond River. You can (1) drive to the house atthe end of the lane and request permission to leave your vehicle in the landowner's yard; then proceed eastward across the field to Hanford Brook; or (2) park on the main road and walk along thelane and partly overgrown bush trail to the stream. In either case Stop 10 is the first low-relief outcrop to be encountered on thesouth bank, proceeding upstream and down stratigraphic section. Note: The water level in the stream is critical; if it is too high, much of the outcrop will be concealed. Therefore, the section isbest viewed in mid- to late summer. Other localities in Saint John where stratigraphically equivalentrocks can be seen are described in field trip guides by Patel (1972, 1973a).
