What is recorded here

You can still picture the western edge of that lost lake, where people drove fire-hardened stakes into the mud and set conical alder traps between them. Fish swam in through the circular opening, became trapped in the narrowing weave, and never found their way back out. The lake vanished into bog and memory, but the weir remains the clearest proof that the place was not empty. It was a kitchen, a workshop, and a hunt conducted in patience rather than speed.

Located in a fairly level landscape at the W edge of what was probably a small lake (dims c. 1.5km NW-SE; c. 0.75m NE-SW) which is described as the ‘Logh and bog of Shrereene’ on the Down Survey (1656-8) barony map and as a ‘Marl Bed’ (max. dims c. 0.5km E-W; c 0.4km N-S) on the 1836 edition of the OS 6-inch map. The original lake was probably coterminous with Commons (Skreen by.) townland. Archaeological testing (04E0418) by J. Dempsey of Testing Area 4, Contract 2, prior to the construction of the M3 motorway identified four upstanding mounds of organic material and marl. Mound A (dims 10.05m N-S; 4.8m E-W; max. H 0.58m) was 2m ENE of Mound B (dims 6.7m x 4.7m; max. H 0.12m). Mound C (dims 4.5m x 4.1m; max. H 0.2m) was 5.6m SE of A while D (dims 1.3m x 1.05m; H 0.15m) was just 2m N of A (Dempsey 2004, 12-13). The area was fully excavated (E003064) by M. Mossop (Mossop M. and Mossop E. 2009) as Clowanstown 1 (excavations.ie 2006:1533) between September and December 2006 when it proved to be a complex area with a Mesolithic post-row structure and stone platform that had four associated fish-traps, together with four Neolithic mounds and excavated features. Four conical fish-traps were within peat layers in the central hollow and are amongst the earliest evidence of human activity. Two were close together at the bottom and two others were at higher levels c. 5m to the S. Each had a circular opening at one end and was made from one to two-year old withies that were mostly alder although some birch was present. At the closed end the withies were tied together externally, creating the conical form. The fish-traps were portable but they could also have formed part of a fixed weir. Twelve samples returned radiocarbon dates ranging between 5300-5000 cal. BC to 4990-4720 cal. BC (BETA 231947 to 231958) placing them in the later Mesolithic. Fish-trap No. 1 (L 1.15m; diam. 0.4m) is fairly typical and had a double twining at the opening. Two samples of its withies produced radiocarbon dates of 5210-4970 cal. BC (BETA 231954) and 4990-4730 cal. BC (BETA 231955). Fire-hardened stakes may have been used to hold the fish-traps in place but one was weighted with stones in the opening.
