Abstract: Closure, temperature and inclination have been measured in a deep drill hole at Byrd Station, Antarctica. The deep hole was drilled to 1013 ft during the 1957-58 summer season, and was first fully instrumented in December 1958. The results of remeasurement in January 1960 and January 1961 indicate that temperatures in the uncased portion of the deep hole (below 150 ft) have stabilized; that the closure rate is increasing; and that insignificant inclination has occurred since the hole was drilled 3 years ago. Results of snow studies in January 1960 show that the present rate of accumulation at Byrd Station is between 14 and 15 cm of water equivalent per year.
