]]> Area distant from ridgelines, wide-open slope https://www.avalanches.org/glossary/#area-distant-from-ridgelines-wide-open-slope Mon, 18 Jul 2022 14:52:03 +0000 http://localhost/eaws/glossary/#area-distant-from-ridgelines-wide-open-slope

Mountain terrain unconnected to a ridgeline.

Further explanation:
Often refers to transitions from extremely steep to less steep terrain. Steep terrain and rocky steps not connected to the main ridge belong in this category. There is no clear boundary line between areas adjacent to or distant from a ridge, it is a transitional zone.
