Keadeen Mountain is not obviously flat-topped either when seen from the N (Church Mtn) or from the contours on the map. Céide can also mean a path, way or a place of assembly, fair site, etc. One of these other meanings may be relevant in this case. As it is a townland name, it may not refer to the mountain originally.
Keadeen Mountain is the 191st highest place in Ireland. Linkback: https://mountainviews.ie/summit/186/
