Sròn a' Choire Ghairbh's main geographical feature is the Coire Glas which has the small Loch a' Choire Ghlais within its upper recesses. The mountain is horse shoe shaped and throws down two ridges on either side of the corrie, the lengthy east ridge is five kilometres long and goes over the two subsidiary tops of Sean Mheall (888 metres) and Meall nan Dearcag (693 metres) before descending to the Kilfinnan Burn at the north end of Loch Lochy. Another ridge called Meall a' Choire Ghlais goes north and then north east along the other side of Corrie Glas, it loses very little height for two kilometres before descending steeply and rockily to the Beallach Easain (548 metres) which connects it to the Corbett Ben Tee.
