This is a notebook diary kept by Leo Luckman recording Tasmanian Caverneering Club trips (following the Club's inaugural meeting of 13/9/1946). The first trip was to the cliffs at Taroona for rope practice (12/10/1946). The details and times of the trips are described, along with some drawings and diagrams which illustrate the text. There is also a list of caves entered and "places to investigate". Leo Luckman was the club's first vice-president.

These records are part of the holdings of the Tasmanian Archives
