The Aneto, located on the Maladeta Massif (Central Pyrenees), is the largest glacier of the Pyrenees. The glacier is 675 m long, occupies an area of 48.64 ha and has a maximum altitude of 3269 m. In this study, we present a detailed area, volume, ice thickness, and Equilibrium Line Altitude reconstruction of the glacier for different periods (LIA, 1957, 1983, 2000, 2006, 2015, and 2017) and analyze its retreat. To estimate the glacier extent during the LIA, the moraines were mapped by using photo interpretation techniques whereas for the recent stages digital satellite images and aerial photographs were used. Moreover, we estimated the topography of the glacier using a simple steady-state model that assumes a perfectly plastic ice rheology, which allowed reconstructing the theoretical ice profiles of the glacier. To reconstruct the ice surface, a digital elevation model was created and combined with the bedrock topography in order to obtain the ice thickness of each stage. The results of the study reveal a considerable retreat of the Aneto Glacier since the LIA. The length of the glacier has reduced from 1970 to 675 m from LIA to2017, and its tongue has retreated from 2385 to 3029 m a.s.l. Furthermore, the glaciated area has been reduced from 245 to 48.64 ha from LIA to 2017 and the ELA has risen from 2919 to 3139 m a.s.l. The data obtained indicates that in the LIA–2017 period the glacier volume has been reduced from 82.57 m × 10⁶ m³ to 3.48 m × 10⁶ m³ and the maximum ice thickness from 95 to 27m. We also reconstructed the climatic conditions, showing an increase in temperature of ~1.14°C from LIA to 2017. These data reveal a vast retreat of the glacier since the LIA, which has accelerated since the 1980’s and even more since the year 2000.

阿内托（Aneto）位于比利牛斯山脉中部的马拉德塔地块（Maladeta Massif），是比利牛斯山脉最大的冰川。冰川长675 m，占地48.64公顷，最大海拔3269 m。在这项研究中，我们介绍了冰川在不同时期（LIA，1957，1983，2000，2006，2015和2017）的详细面积，体积，冰厚度和平衡线高度重建并分析了其退缩。为了估计LIA期间的冰川程度，通过使用照片解释技术来绘制rain的图，而在最近阶段，使用了数字卫星图像和航拍照片。此外，我们使用简单的稳态模型估算了冰川的地形，该模型假定了完美的塑性冰流变性，从而可以重建冰川的理论冰廓线。为了重建冰面，创建了一个数字高程模型，并将其与基岩地形相结合，以获得每个阶段的冰厚。研究结果表明自LIA以来Aneto冰川有相当大的退缩。从LIA到2017年，冰川的长度从1970年减少到675 m，而舌头的asl从2385减少到3029 m。此外，从LIA到2017年，冰川面积从245减少到48.64公顷，而ELA从2919至3139 m asl所获得的数据表明，在LIA–2017年期间，冰川体积已从82.57 m×10减小⁶  m ³到3.48 m×10 ⁶  m ³，最大冰厚从95到27m。我们还重建了气候条件，显示从LIA到2017年的温度升高了约1.14°C。这些数据显示自LIA以来冰川的大幅度退缩，自1980年代以来加速了，甚至自2000年以来更加加速。
