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.

位于西伯利亚阿尔泰山脉的Mashej湖是由一个由终碛组成的大坝形成的，该大坝覆盖着岩石冰川和侧向落石碎片。直到2012年7月爆发，该湖在过去400年中发展到最大程度。在临时淹没的湖盆内的死树干记录了湖泊的延伸，通过它们死亡的时间点和它们年度记录中的环境条件。 通过对已经采样的树干进行树木生态学分析，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，树木年轮中继承了大量的数据。除了湖泊本身的发展外，这些数据可能填补了对位于欧洲和中亚中心之间的地区自然环境发展的认识方面的一个重大空白。
