Description:
A dissected wedge of flat-topped valley-fill remnants lies to the southwest of Teeavan Hill in the Upper Owenrigh valley. An exposure of cross-bedded medium sand and pebble gravel foresets dips generally northwards at 20-25° [C672 042] with foreset heights reaching 200m O.D. The deposits feather laterally against the rising slopes of the surrounding hills or are truncated by a rock-cut meltwater channel. To the south, hummocky topography extends in a thinning wedge for about 1km. Post-depositional erosion has dissected the delta into three fragments separated by steep-sided rock-cut meltwater channels now occupied by the Cushcapal Water, Glenedra Water and the Altnaheglish River.
