' [Report 1145]

Alternative Names: CI40

Notes: Dimensions are estimates.

The NGRs of this group of caves (CI75, CI41 & CI40) are, as far as possible, consistent with photo 1, an aerial map layer and the latitudes and longitudes given in Report 1145. But they may need some modification because the aerial has the shoreline in shadow and a larger scale context photo would be really helpful.

Links and Resources:

One OS layer has a cave dot close to the above NGR, and also has 'caves'. Other layers have 'cave'.
