This number used to be allocated, before Easter 2018, to "a series of 4 choked shafts along a wooded depression" with grid reference 30T 452755 4798025 (Datum: ETRS89). These four, and more, were documented in April 2018. See sites 4740, 4741, 4742, 4743, 4744 and 4745.

Site 0351 is now a single hole - a 3m deep spiral down to a tiny, leaf-covered floor with no draught.
