494 THE FRESH- WATER LOCHS OF SCOTLAND 
The upper part of the loch^ which is outside the valley, follows the 
line of shatter-belt of the Fasagh fault. The valley in which the 
greater part of Loch Damh is situated formed an outlet for the 
large mass of ice that flowed into Loch Torridon. It is evident 
that the Lewisian Gneiss has resisted erosion more successfully 
than the Torridon arkoses. 
Davan. — In glacial deposits, 
Deaspoirt, nan. — Irregular rock-basin in Lewisian Gneiss ; one of a 
chain of similar rock-basins. 
Dee. — Rock-basin in granite, partly ponded by drift. 
Deighe fo Dheas, na. — Rock-basin in Lewisian Gneiss. 
Deoravat. — Rock-basin in Lewisian Gneiss. 
Derclach. — Small rock-basin in greywackes, -whose waters flow into 
Loch Finlas. 
Derculich, — Rock-basin in phyllites and limestone. 
Dhomhnuill Bhig. — Irregular rock-basin in Lewisian Gneiss. 
Dhu (Portsonachan Hill). — Resting partly on drift and partly on meta- 
morphic rocks. 
Dhugaill (Torridon basin). — Rock-basin in Torridon Sandstone along line 
of shatter-belt. 
Dhughaill (Carron basin). — -Ponded by moraines and fluvio-glacial 
material. The deepest part is probably a rock-basin lying in 
crystalline schists and Cambrian strata along the line of the Moine 
thrust-plane and the Glenmore fault. The lake evidently extended 
along the valley to Craig, but has been silted up by the alluvium 
of the Carron and its tributaries. 
DiBADALE. — Corrie rock-basin in Lewisian Gneiss. 
Dilate. — Small rock-basin in crystalline schists, draining into Loch 
Shell. 
DiTHREiBH, AN.— Vol. II. Part I. p. 331. 
DocHARD. — Rock-basin in crystalline schists. 
DocHART.— Vol. II. Part I. p. 13S. 
DoiNE.— Vol. II. Part I. p. 45. 
DoiRE Daraich, na.^ — ^Rock-basin in Lewisian Gneiss. 
DoiRE nam Mart. — Rock-basin in crystalline schists, probably along 
shatter-belt (see mite, Loch Arienas). 
Doon.— Typical rock-basin in Lower Silurian strata and granite. It has 
two distinct basins. The upper and deeper one lies in the granite, 
its barrier being composed of the belt of hornfels that crosses the 
loch near the Wee Hill of Craigmulloch ; the lower one is situated 
in Silurian strata, whose outlet is a tunnel driven through a well- 
glaciated i^ocke ?noidomiee of greyw^acke. The Gull Islands and the 
shores of the Ford of Moak consist of moraines, while the islands in 
Garpel Bay are roches inoutonnees. 
Dornal. — Ponded by boulder clay and moraines, resting on Silurian 
greywackes.
