Longevity and growth of retrogressive thaw slumps. a Percent of all observed features remaining active for a given duration. Best-fit relation is for retrogressive thaw slumps >2 years old and for sample size >30 (upper solid line). Dotted lines are 95% confidence intervals. Lower solid line is sample size. All retrogressive thaw slumps were active for at least 3 years. b Measured area of sampled active retrogressive thaw slumps against age. Best-fit line was constrained through the origin. Dotted lines are 95% confidence intervals
