Köppen climate type:


Adjacent from Honda dealership downtown by the movie theater. {Off I-95 exit 3 near Arch Street?). This area was recently (2006) blasted to clear a space for construction. Very nice doubly-terminated crystals of albite can be found as well as nice gemmy blue-green to yellow beryl. The rock here is extremely hard, bring heavy tools. Property is for sale currently and although collecting is OK as long as no power tools are used, police have stopped by just because they were curious as to what people were doing there.
