Lake Mashej, located in the Siberian Altai Mountains, is formed by a dam consisting of a terminal moraine with a covering rockglacier and lateral rockfall debris. Until its outburst in July 2012, the lake developed during the last 400 years up to its maximum extension. Dead tree trunks within the temporary inundated lake basin loged the extension of the lake by the point of time of their death and the environmental conditions within their anual records. By dendroecological analysis of the already sampled tree trunks the development of the lake and the related climatological and environmental signals will be decoded. A previous random test indicated a significant amount of data inherited in the tree rings. In addition to the development of the lake itself, the data might fill a significant gap on the knowledge of the natural environmental development of the area located between Europe and the heart of Central Asia.

马沙湖（Lake Mashej）位于西伯利亚阿尔泰山脉（Altai Mountains），由一个大坝组成，该大坝由冰a的末端组成，上面有覆盖的岩石冰盖和侧面岩石碎片。直到2012年7月爆发，该湖在过去的400年中发展到最大延伸。临时被淹没的湖泊湖中的死树树干将湖泊的延伸时间延伸到其死亡的时间点以及其动态记录中的环境状况。 通过对已经采样的树干的树突生态分析，将解码湖泊的发展以及相关的气候和环境信号。先前的随机测试表明在树环中继承了大量的数据。除了湖泊本身的发展外，数据还可能填补有关欧洲和中亚心脏中心地区自然环境发展的重要空白。
