International audience Retrogressive thaw slumps (RTS) result from the thermal destabilization of icerich permafrost as a consequence of increasing subsurface temperature • Experimental RTS were designed to simulate the thawing of ice-rich permafrost with vertical and horizontal ice layers • Our laboratory simulations show how ground ice heterogeneities influence RTS development Accepted Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.
