Last Wednesday evening, after spending most of the day with a group from Macclesfield in Mouldridge Mine, and with my DCA "Gasman" hat on, I decided that, having only just recently measured the air quality in Lathkill Head Cave, and Lathkill Head Upper Entrance, it might be a good idea to do the same in the only other entrance - Garden Path.
Lathkill Head Cave
In response to a report of high CO2 levels in Lathkill Head Upper Entrance, a small group of us (Ann Soulsby, Christine Wilson, Andy Chapman and me) descended the cave, and, using the DCA CO2 meter, Ann measured the atmosphere at various locations. The following was reported back to DCA.
Foot of rope in Waiting Room: 1.55%
Top of choke at the bottom of Waiting Room: 1.70%
