A.C. Zecchell 1960 JOURNAL 2 mi. E Antioch, Contra Costa Co., California Feb. 21 to 2 mi. E Antioch & worked the (cont.) "PSE-A" (meaning??) Recreation Area. - A similar oak grove but furnished with picnic tables & fire places. Not much litter or boros but under a long board under it by digging up an inch or so soon - buckeye trees, found the 5th Antiochia. About 400-500 yards of grassy field separate the 2 oak groves where the limbs were connected (so both given same locality on maps). The field is muddy in places & is used, at one end, as a dump. Looked under some boros but saw no Antiochia. Besides these 2 areas only saw 2 other oak groves among which were scattered trees, worked one of these but got no boros. Locality outlines below.
