The Dale area is located on the western shore of the Bíldudalsvogur bay, in the southern part of the Dalefjord. Its topography consists in the extensive summit plateau of the Dalefjal mountain, at 460 m a.s.l., and of a 300 m high headwall, that faces SE. The headwall is deeply carved with two 400 m wide gullies, the A-gil gully to the south and the B-gil gully to the north. Sediments transferred from the gullies have formed large colluvial fans below them, which can be followed down to the present shoreline. The A-gil cone is especially studied here, as the B-gil one encountered several man-made changes that considerably modified its surface. Between the two large basins several smaller gullies occur, named the M-gil gullies. Slope gradients vary from 20° to 65°. The Dale village (c. 300 inhabitants) is located on the narrow rim of land, along the shoreline (Fig. 2).

A subpolar oceanic climate, very variable with frequent temperature and precipitation changes, characterize the area. Mean annual air temperature is 1°C, and annual precipitation amount is 90 mm.

The Dale area is also prone to debris-flow and snow-avalanche activity.
