Langbank East crannog was noticed on aerial photos in the early 1970s, and at that time piles were apparently sometimes seen protruding through the sand.
An investigation in 1997 revealed a low mound of stones that had been scattered irregularly. At the highest point was a roughly rectangular feature in stone. To the north of the main crannog site were what appeared to be stone-edged roughly circular pools which held water at low tide.
Between the crannog and the shoreline are two parallel lines of stones which have been interpreted as either a causeway of some kind, or a delineated trackway.
The RCAHMS list the location of this crannog as unverified. However the location of Langbank East crannog seems to be visible on the Google Maps aerial view as a circular dark patch, just to the south of the quoted co-ordinates, at NS 4050 7310 (55.925118,-4.554155).
