Alphine Twister Cave

Lime Creek Cave and Alphine Twister Cave contain sand to cobble-sized fill derived from igneous and metamorphic rock (Ft). In Alphine Twister, these deposits overlie a bedrock floor, and are 1 m (3 ft) below the cemented Fml deposit. In Lime Creek Cave, these sediments are cemented by calcite and are, in turn, overlain by reworked fill (Fml). This relationship is contrary to what is observed in Alphine Twister Cave where the Fml deposit appears to be older. This may indicate that there were two episodes of Fml deposition, separated by an episode of Ft deposition.

Alphine Twister Cave has evidence of a second major period of stream activity that downcut and reworked earlier deposits. Current deposition may be characteristic of the quiescent phase of sedimentation. A perennial stream flows in the lower part of the cave and transports silt and sand-sized materials. The upper part of the cave is characterized by calcite accumulation, breakdown, and organic fill brought in by animals. 

Flowstone and calcite cement were used as indicators of relatively low energy. In active stream passages, older calcite-cemented sediments are actively being incised. Presumably, the calcite could have been deposited in the stream paths only during full glacial conditions when streamflow would have been minimal (Ford, 1979). In Alphine Twister, calcite speleothems are currently being deposited in parts of the cave away from active streams.
