Rock rubble in the White Water Valley in the Tatras.

Painted in 1892, this study of boulder-strewn terrain in the White Water Valley (Dolina Białej Wody) of the Tatra mountains represents Gerson's sustained engagement with the geological drama of Poland's highest mountain range. The White Water Valley, on the Slovak side of the Tatras, offered a particularly rugged landscape of glacial debris and fast-moving streams that challenged painters accustomed to the softer scenery of the Polish lowlands. By the early 1890s, Gerson had been making regular painting expeditions to the Tatra region for decades and had developed a confident, quasi-geological approach to depicting rock formations, scree, and mountain water. This late-career canvas reflects the mature naturalist sensibility that distinguished his mountain work from earlier, more dramatically Romantic approaches to the same terrain. His treatment emphasizes direct observation of specific natural phenomena over the construction of picturesque or sublime effects.

Oil on canvas with a cool, high-altitude palette dominated by greys, blue-greens, and ochres. The handling of rock rubble and stream-worn stone is notably precise, suggesting extended direct observation. Gerson's mature technique uses controlled impasto for textured rock surfaces and more fluid brushwork for water and atmospheric passages.
