Geology and Vegetation
That disposition of the big geological formations sticks to a distinctive north-south pattern of the short Gipuzkoan valleys ending up in the Bay of Biscay. The present area stands on the westernmost end of the Pyrenees, where outcrops of slate, sandstone, conglomerates, red silt and other materials can be found, largely from the Paleozoic Era and Mesozoic Era.
The vegetation landscape is split in two distinctive sides, the first one locating on the Eastern slopes and the second on the Western part. On the former patches of autochthonous forest and vegetation abound, while on the latter (especially on the way down to Leitzaran) pine tree used for logging (aka Pinus radiata) prevails. There are noticeable grassland strips for grazing sheep and horses interspersed with forest.

Famous quotes containing the word vegetation:
“I would not have every man nor every part of a man cultivated, any more than I would have every acre of earth cultivated: part will be tillage, but the greater part will be meadow and forest, not only serving an immediate use, but preparing a mould against a distant future, by the annual decay of the vegetation which it supports.”
—Henry David Thoreau (1817–1862)
