The project continues with recent additions including a volumetric survey of Titan and a re-survey from Speedwell's Main Rising to Whirlpool Rising.
Dave Nixon has completed the volumetric survey of Titan (using a Disto X and Trimble Recon PDA). This will be integrated this into the main Castleton area survey but in addition it will allow Titan's volume to be accurately calculated for the first time.
The splays were taken at 5m intervals while descending the main upper and lower pitches, and from Horne's Gully ascending to the east.
