Nope. But interesting not on the glacier and lake.

"Around 1920 the Stein Glacier completely covered
the present position of the lake (Fig. 2b). In 1924 the glacier
began to retreat. Subsequently the glacier’s surface strongly
decreased until the terminal moraine started to dam the melt-
water masses (Fig. 2c). "
