498 THE FRESH-WATER LOCHS OF SCOTLAND 
Gainmheich, — Valley rock-basins in Lewisian Gneiss and Torridon 
Sandstone. 
Gamhna. — Kettle-hole in fluvio-glacial materials. 
Garbh-Abhuinn, na. — Rock-basin in Lewisian Gneiss. 
Garbh-Abhuinn Ard, na. — Rock-basin in Lewisian Gneiss. 
Garbhaig.— Vol. IL Part I. p. 239- 
Garbh-Clachan, nan. — Rock-basin in Lewisian Gneiss. 
Garry (Ness basin). — Simple rock-basin down as far as Garbh Eilean^ 
below which there is a shallow expansion with a waterfall near the 
outlet. 
Garry (Tay basin). — Rock-basin in graniilitic schists along shatter-belt. 
The steep-sided valley in which it lies has been pirated from the 
Spey system by a tributary of the Tay. The great suite of 
moraines emanating from this valley^ traceable far down the Garry, 
shows what a powerful glacier must have occupied the site of this 
loch during the later glaciation. 
Gartmorn. — Artificial reservoir on boulder clay resting upon Upper 
Carboniferous strata. 
Garve.— Vol. II. Part L p. 289- 
Gead, an.— Vol. II. Part I. p. 353. 
Geal. — Typical delta loch cut off from Loch Lomond and enclosed in the 
advancing delta of the Falloch. Loch Buidhe at the head of Loch 
Lubnaig has a similar origin. 
Gealaich, na. — Moraine-dammed on quartzite and epidiorite. 
Geireann, nan. — Tidal loch ; probably a rock-basin along the strike of 
the Lewisian Gneiss. 
Geireann, nan (Mill). — Rock-basin in Lewisian Gneiss. 
Gelly — Partly artificial, in drift resting on Lower Carboniferous strata. 
Ghiuragarstidh. — Vol. II. Part 1. p. 240. 
Ghlinne-Dorcha, a'. — Rock-basin in Lewisian Gneiss. 
Ghobhainn, a'. — Rock-basin in Lewisian Gneiss. 
Ghriama, a'. — Rock-basin in Moine schists. 
Ghuilbinn. — Valley rock-basin in Strath Ossian. 
GioRRA. — Rock-basin in crystalline schists. 
GiRLSTA. — Rock-basin in crystalline schists and metamorphic limestones; 
may be partly due to solution. 
Gladhouse. — Artificial reservoir in wide valley carved out of Upper Old 
Red Sandstone and overlaid by boulder clay. 
Glass.— Vol. II. part I. p. 290. 
Gleann a' Bhearraidh. — Rock-basin along fault throwing down the Lower 
Old Red volcanic rocks of the Lorne volcanic plateau against the 
underlying sediments and crystalline schists. 
GoRM Loch Mor.— Vol. II. Part I. p. 307. 
Gown. — Ponded by moraines and fluvio-glacial gravels of the Achnasheen 
terraces. 
Grass Water. — Lying in boulder clay.
