<underground_description>A tight shaft which descends beside a wall of black ice to a small chamber. The way on is a small squeezy pitch-head over a boulder to another small chamber. A further small pitch head leads into Turbine Hall: another shaft which begins on an ice slope and drops into a straight hang. This larger hang lands on another ice slope. Here, a small rift at floor level has an awkward tight section and leads to a big shaft, Jabberwocky (surveyed at 64m vertical range).
<br>
<br>
At the base of Jabberwocky are three horizontal continuations. Purple Prickle Passage (west side, walking-size passage covered in popcorn) has been explored to its terminus (46m long) at a too-tight rift with voice connection to the main chamber (and contains a few C leads). Another passage drops below the waterfall at the opposite side of the chamber (the east), with continuing passage sloping downwards on the left and a horizontal passage doubling back to the right. At the south end of the chamber, there is a continuation up an unexplored climb. Around twenty metres up the wall of the shaft between the entrance to Purple Prickle Passage and the waterfall lead is a large window which potentially connects to a parallel shaft.</underground_description>
