North Lunga Geo cave

Large entrance and a wide passage ~60m long. A blow hole exists at the back from which blasts out spray and smell of decaying seaweed as the swell rises. Bedrock and boulder floor throughout, approx 5m water depth. [SNH Report 102: Cave inventory p 124]

Notes: SNH Report 102 has HU 15372 60291 as the entrance location. However this plots a little way W and offshore on Canmore Aerial - so it may be that this location is where the dive boat was moored while the cave was swum into.

Current OS layer 10 on Canmore has two cave dots at HU 15400 60293 & HU 15402 60283. These probably correspond to the double entrance separated by a big pillar as shown in the Report 102 plan below.
SNH Report No. 102 Site Condition Monitoring: surveys of marine rocky environments in the Papa Stour cSAC July-August 2003 (ROAME No. F02AA409b) has this cave in its cave inventory as site 22.
Video by Ryan Leith in 2009. The entrance pillar is a bit smaller than in the sketch below.
