本勘误表修正了21 Ne浓度报告中的一个错误，该错误影响了一批样本，这些样本包括基岩深度剖面，宇宙成因的10 Be、26 Al和21 Ne被建模，以限制爱国者山的年龄和暴露历史（手稿中的图8）。重新建模的宇宙成因核素数据使用校正后的21 Ne数据产生的表观暴露年龄为3.5-5.1 Ma。这纠正了Sugden等人（2017年）发表的2.1-2.6 Ma的年龄，并加强了原始论文的结论，即冰川纵倾线是前第四纪的，其侵蚀所需的气候条件最后发生在中新世中期。修订后的补充表1已更新，更正了21 Ne浓度，并一致报告了10 Be浓度。修订后的补充表2已更新了受影响批次样品的21 Ne暴露年龄。下面，我们描述了修改后的模型结果，并给出了修改后的图8。表1和表2、图8及其标题取代了原文中的内容。这些更正加强了原论文的结论。
This corrigendum fixes an error in the reporting of 21Ne concentrations, which affected one batch of samples that included the bedrock depth profile from which cosmogenic 10Be, 26Al and 21Ne were modelled to constrain the age and exposure history of the Patriot Hills (Fig. 8 in the manuscript). Re-modelling the cosmogenic nuclide data using the corrected 21Ne data yields an apparent exposure age of 3.5–5.1 Ma. This corrects an age published as 2.1–2.6 Ma in Sugden et al. (2017), and reinforces the conclusion of the original paper that the glacial trimline is pre-Quaternary and that the climatic conditions necessary for its erosion last occurred in the Mid-Miocene. The revised Supplementary Table 1 has been updated with corrected 21Ne concentrations and consistent reporting of 10Be concentrations. The revised Supplementary Table 2 has been updated with 21Ne exposure ages for the affected batch of samples. Below, we describe the revised model results and present a revised Fig. 8. Tables 1 and 2, Fig. 8 and its caption replace those in the original paper. The corrections reinforce the conclusions of the original paper.
