Definition

“A central crack or trough flanked by two raised edifices, up to a few hundred meters high and less than 5 km wide” (Kattenhorn and Hurford 2009).

Synonyms

Doublet ridge; Ridge; Ridge pair; Trough-bounding ridge pair

Note

Double ridge is the most common type of ridge on Europa: the term ‘ridge’ usually refers to double ridge.

Description

(Seen as triple band in Voyager images) A ridge pair with a continuous, V-shaped medial trough whose depth is less than the height of the ridges. They are 100s m wide on average, though in some cases are up to less than 5 km across (Kattenhorn and Hurford 2009; Greeley et al. 2000). Double ridges are the most ubiquitous morphology on Europa and run almost linearly with generally uniform morphological characteristics for up to more than 1,000 km (Prockter and Patterson 2009 and references therein). The majority of ridge slopes are <20° (Coulter and Kattenhorn 2010; Coulter 2009) and display mass-wasting features (e.g., Head et al. 1999). The...
