[[File:Ground moraine 9004.jpg|thumb|Ground moraines create irregular, rolling topography near [[Gainesville, New York]].]]

Ground moraines are till-covered areas with irregular topography and no ridges, often forming gently rolling hills or plains,{{sfn|Jackson|1997|loc="ground moraine"}} with relief of less than {{convert|10|m||sp=us}}. Ground moraine is accumulated at the base of the ice as [[Till#Types of till|lodgment till]] with a thin and discontinuous upper layer of supraglacial till deposited as the glacier retreats. It typically is found in the areas between end moraines.<ref name=HiltJohnsonMenzies2002>{{cite journal |last1=Hilt Johnson |first1=W. |last2=Menzies |first2=John |title=Supraglacial and ice-marginal deposits and landforms |journal=Modern and Past Glacial Environments |date=2002 |pages=317–333 |doi=10.1016/B978-075064226-2/50013-1|isbn=9780750642262 }}</ref>

====Rogen moraines====
{{Main|Rogen moraine}}

Rogen moraines or ribbed moraines are a type of basal moraines that form a series of ribs perpendicular to the ice flow in an [[ice sheet]]. The depressions between the ribs are sometimes filled with water, making the Rogen moraines look like [[tigerstripe]]s on [[aerial photograph]]s. Rogen moraines are named after [[Lake Rogen]]<ref name=Moller>Möller, P., 2006. Rogen moraine: an example of glacial reshaping of preexisting landforms.

====de Geer moraines====
Closely related to Rogen moraines, de Geer moraines are till ridges up to 5m high and 10–50m wide running perpendicular to the ice flow. They occur in large groups in low-lying areas.<ref name = "nominate">{{cite report |title = The Kvarken Archipelago |url = http://whc.unesco.org/uploads/nominations/898bis.pdf |author = Metsähallitus (Forest and Park Services) |date = 16 July 2006 |access-date = 3 October 2021}}</ref> Named for [[Gerard De Geer]], who first described them in 1889, these moraines may have developed from crevasses underneath the ice sheet.<ref name = "nominate"/> The [[Kvarken Archipelago|Kvarken]] has a very high density of de Geer moraines.<ref>{{cite journal |last1=Kotilainen |first1=Aarno T. |last2=Kaskela |first2=Anu M. |last3=Bäck |first3=Saara |last4=Leinikki |first4=Jouni |title=Submarine De Geer Moraines in the Kvarken Archipelago, the Baltic Sea |journal=Seafloor Geomorphology as Benthic Habitat |date=2012 |pages=289–298 |doi=10.1016/B978-0-12-385140-6.00017-7|isbn=9780123851406 }}</ref>
