1789: sink
Riaño 30T 452568 4799701 (Datum: ETRS89. Accuracy code: M) Altitude 250m
Area position

Updated 26th September 2012

A sink at the end of a dry valley that takes a lot of water in wet weather. Choked with mud and branches with a "plug hole". The position was thought to be incorrect in 2012 but that would place it on the other side of a building. It is possible that this has been covered over. (See site 3727).
