504 THE FRESH-WATER LOCHS OF SCOTLAND 
remains of the lower raised beaches are found at intervals nearly 
up to the head of the loch, so that during their formation the ice 
had retreated from the whole valley. 
Since that time, Loch Lomond has been silted up to some extent 
by the Fruin and the Endrick near its foot, and by the Falloch at its 
head, and the delta of the Falloch has isolated a part of the lake, 
thus forming the Geal or White Loch, a typical delta lake. 
LosGAiNN MoR, AN. — Rock-basin in schists and epidiorite, with morainic 
material along its banks. Its lower end has been silted up by 
streams entering it from the south. 
LosGANAN, NAN. — A mere pool in drift. 
Lowes (Tay basin). — Ponded by drift resting on schistose grits. 
Lowes (Tweed basin). — ^Upper end of St Mary's Loch, and separated 
from it by deltas (see St Mary's Loch). 
LoYNE. — A chain of shallow rock-basins in Glen Loyne, partly silted up. 
LuBNAiG. — Vol. n. Part L p. 45. 
LuiCHART.— Vol. IL Part I p. 288. 
LuNDiE (Glen Garry). — Irregularly shaped loch, partly a rock-basin and 
partly ponded by moraines. 
LuNGARD. — Typical valley rock-basin in crystalline schists near the head 
of Glen Cannich, 
LuNN DA Bhra. — Shallow lake with moraines practically on the watershed. 
Lure. — Ponded by drift resting on Silurian greywackes and shales. 
LuRGAiN.— Vol II. Part I. p. 190. 
Lyon. — Valley rock-basin in crystalline schists along line of Tyndrum 
fault. 
Maberry. — In boulder clay and moraines overlying Silurian greywackes 
and shales. 
Magillie. — Kettle-hole in fluvio-glacial deposits. 
Mama. — Rock-basin in schists, separated from Loch na Creige Duibhe 
by delta of Allt Dearg. 
Maol a' Choire.— Vol. IL Part I. p. 19I. 
Maree. — Composite rock-basin, partly along the Glen Docherty shatter 
belt, and partly in Lewisian Gneiss and Torridon Sandstone outside 
of this line of disturbance. The horizontal displacement of the 
geological structure lines in the neighbourhood of Kinlochewe, and 
the shattering of the rocks are prominent features of this disruption. 
It also has a down-throw of 1000 feet to the north-east. It enters 
the lake at its head, and runs near the northern shore to a point 
opposite Eilean Subhainn, where it leaves the loch and traverses 
the precipitous slope behind Ardlair. Beyond that mansion-house 
it once more enters the lake, passes down the River Ewe to within 
a mile of Poolewe, and extends north-west to Camas Mor east of 
the Rudh' Re. 
The soundings show that the lake contains three basins. The 
upper one, extending from the head of the loch to a point opposite
