Portal Pool is now effectively closed for the winter and the aim of this project is to complete a bypass to the Frozen Cascade by engineering a route from Sand Dig (in 100 Fathom Passage) to The Timeline. This will allow the 2009 extensions to be open for trips from next summer but please note that as Portal Pool and Diesel Duck sump during the winter (and also after heavy rainfall) that these passages will be only accessible for a maximum of 4-5 months a year.
The 2008 extensions have been open for trips since last November and there are 18 leaders for Charterhouse and include 2 leaders specifically for non CCC clubs. The 2008 extensions are not weather dependent.
