5005: Tractor Tyre Shaft
Barrio la Mina 30T 445703 4799917 (Datum: ETRS89. Accuracy code: M) Altitude 268m
Length 15m Depth 9m
Area position

   A tractor or wagon tyre blocked this hole when it was found in the summer.
   A 4m pitch leads to two ways on. Down is a tight vertical squeeze to a choke. Horizontal is a low crawl through loose boulders which then becomes too small.
   Just up the slope a few metres are two overtight rifts.
