It is bounded on the north by [[Shaman Creek]] valley, on the south by [[Chakima Creek]] valley, on the east by [[Kakiddi Creek]] valley and on the west by the [[Big Raven Plateau]].<ref name="Souther">{{cite map|last1=Souther|first1=J.

The lower slopes of Cartoona Ridge are covered with [[felsenmeer]], [[till]] and [[glacial]] and [[fluvial]] [[outwash]], as well as [[solifluction]] deposits. The lowermost rock outcrops are [[Miocene]] [[alkali basalt]] flows of the [[Raspberry Formation]]. Overlying these rocks are Miocene [[comendite]]s and [[trachyte]]s of the [[Armadillo Formation]] which are in the form of [[pumice]], [[ash flow]]s, [[tuff]]s, [[lava]] flows and [[lava dome]]s. The Armadillo Formation at the westernmost end of Cartoona Ridge is overlain by [[Pliocene]] alkali basalt of the [[Nido Formation]].<ref name="Souther"/>
