   A small hole by a flat area gives entry to a roomy 20m shaft. Landing is on boulders with a slight draught. These have been dug as its position is directly over Rocky Horror in Cueva Hoyuca (107).
   The site could not be found in August 2019 nor in July and December 2021, April 2022 or December 2023 and January 2024, possibly due to heavy vegetation.

   This shaft may have first been found in 1979 while molephoning - see 1979 summer logbook p35 then p29 and p30. The 1981 BCRA Transactions does not mention "229" but the 1981 logbook, p6 has the "relocation" (and also 249 and 250 - numbers which apparently duplicated #0177 and #0178 when used in the 1981 publication).
