Geology The top of the Tons river is in the Himalayan Crystalline complex. It then flows through Tethan Himalaya rocks before connecting to the Pabbar River in the Lesser Himalayan Sequence. The Tons flows into the Yamuna River after crossing into the Sub-Himalaya Sequence. In Art and Literature An engraving of a painting by William Purser depicting a rope bridge crossing the river in Fisher's Drawing Room Scrap Book, 1839 gave rise to the poetical illustration "Crossing the River Tonse by a Jhoola" by Letitia Elizabeth Landon. The poet echoes the three stranded rope in her three-lined verses.
