Directly off the Tunnocks path we got distracted as we came upon 3 shafts which were not on the GPS catalogue: we named them 2018-PF-01 (which we tagged; see our survey of the same day), 2018-PF-02 (which we tagged the next day with Wookey; undescended), and 2018-PF-03 (which Paul tagged some days later)</entrance_description>
