This is the sink point for the stream which enters the G.B. Cave at Boulder Chamber. Now blocked, the stream once followed a sizeable passage which ended in a choke and an impassable rift. UBSS commenced digging the site in 1921 and entered the cave in 1923.
Alternate Names: Tyning's Stream Swallet
Notes: Opened by UBSS in 1923 but entrance now blocked with debris.
