[6] Despite a busy and challenging life managing Estancia Harberton and family on the Beagle Channel in the 1960s, Goodall found the time and energy to study and draw the natural history, flora and fauna of the surrounding area, and eventually of Tierra del Fuego as a whole.
[6][7] A self-described "beachcomber", Goodall also started collecting dolphin and whale specimens during this time, especially skulls, from local cetacean strandings.
[6] Goodall collected plants with several other notable botanists including Lincoln Constance, Alicia Lourteig, Theodore Robert Dudley, David Moore, and others.
In 1970, Goodall published a bilingual English-Spanish book, Tierra del Fuego, containing studies of the local flora and fauna, as well as historical information about the settlement of the area.
[citation needed] On a trip to western South America with a fellow teacher, Prosser visited the Tierra del Fuego area, having been inspired by Lucas Bridges' book Uttermost Part of the Earth.
[citation needed] Goodall and her husband continued to maintain Estancia Harberton for the remainder of her life, raising two daughters, Anne and Abby,[5] on the ranch and in the nearby city of Ushuaia.
Her husband, children, and six grandchildren[5] are the fourth, fifth and sixth-generation descendants, respectively, of Thomas Bridges, the builder of Estancia Harberton and an Anglican missionary credited with spreading Christianity in the Tierra del Fuego region.
