and Bhotan. Southwards the view is bounded by snowy mountains, and
the valley seems blocked up by the remarkable moraine-like spur which
I passed above Keadom.

Stupendous moraines rise 1500 feet above the Lachoong in several
concentric series, curving downwards and outwards, so as to form a
bell-shaped mouth to the valley of the Tunkrachoo. Those on the upper
flank are much the largest; and the loftiest of them terminates in a
conical hill crowned with Boodhist flags, and its steep sides cut
into horizontal roads or terraces, one of which is so broad and flat
as to suggest the idea of its having been cleared by art.

On the south side of the Tunkrachoo river the moraines are also more
or less terraced, as is the, floor of the Lachoong valley, and its
east slopes, 1000 feet up.* [I have since been greatly struck with
the similarity between the features of this valley, and those of
Chamouni (though the latter is on a smaller scale) above the Lavanchi
moraine. The spectator standing in the expanded part below the
village of Argentiere, and looking upwards, sees the valley closed
above by the ancient moraine of the Argentiere glacier, and below by
that of Lavanchi; and an all sides the slopes are cut into terraces,
strewed with boulders. I found traces of stratified pebbles and sand
on the north flank of the Lavanchi moraine however, which I failed to
discover in those of Lachoong. The average slope of these pine-clad
Sikkim valleys much approximates to that of Chamouni, and never
