Le Pouce (French: [lə pus]; English: "The Thumb") is the third highest mountain in Mauritius, at 812 meters (2664 feet).

[4] Le Pouce is the second highest peak in the Moka Range, which was formed ten million years ago from volcano eruptions.

He recorded in his journal: [On 2 May] I ascended La Pouce [sic], a mountain so called from a thumb-like projection, which rises close behind the town to a height of 2600 feet.

The centre of the island consists of a great platform, surrounded by old broken basaltic mountains, with their strata dipping seawards.

The central platform, formed of comparatively recent streams of lava, is of an oval shape, thirteen geographical miles across, in the line of its shorter axis.

There appears to me to be insuperable objections to this view: on the other hand, I can hardly believe, in this and in some other cases, that these marginal crateriform mountains are merely the basal remnants of immense volcanos, of which the summits either have been blown off, or swallowed up in subterranean abysses.
